Historical Cone Collapses in the Southwest Pacific

Ritter (PNG) 1888. Major cone collapse without signs of volcanic eruptions

led to the formation of a Tsunami 12 to 15 meters high on nearby islands. An early missionary

map shows the positions of villages in western New Britain that no longer exist. Several

hundred people were probably killed.



Ambae (Vanuatu) 1913. A lateral collapse after a large earthquake generated a landslide that

Caused possibly about 50 deaths.



White Island (New Zealand) 1914. This volcano located 48 kilometers offshore from the

North Island has a horse-shoe shaped crater just above sea-level. Part of the crater rim

collapsed along a fault on or about September 10th and fell to the crater floor. There were 11

fatalities. No Tsunamis were reported.



Ruapehu (New Zealand) 1953. The upper portion of Ruapehu's crater wall failed on Christmas

Eve releasing more than 1 million cubic meters of Crater Lake waters. The collapse was

relatively small but resulted in a devastating lahar that swept away a railway bridge as the

main Wellington-Auckland express train was crossing and 151 lives were lost in what has

become known as the  Tangwai Disaster.



Tinakula (Solomon Islands) 1966. A landslide of unknown cause slipped into the sea from

the high wall of an ancient avalance amphitheater. There may have been a Tsunami but no

lives were lost.



Lopevi (Vanuatu) 1975. A landslide associated with a lava flow from the summit crater

plunged into the sea. No Tsunami was recorded but the residents have now been permanently evacuated.

MT ULF UPDATE: June 1, 2005

Note: The San Jacinto Fault Alert along with Inland Empire advisory continues to stay in effect. There was moderate infrasonic harmonic resonant activity below 2 Hz on Wednesday. The Peak (Crustal) Infrasonic Harmonic Resonant Frequency was measured at 1.43 Hz (-71.24 dBv). The ULF and MT activity level was low to moderate during the past 24 hours. The inferred mean average unclamping level was higher. The ULF mean average was decreased (negative). The MT peak reading was measured at 10.0 units of regional lithospheric stress. The MT mean average was measured at 8.1 units.

All daily charts were updated to reflect the latest analysis.

General Discussion:
Infrasonic resonant harmonic activity was extremely active during the past 24 hours. There was peak activity at 0.94 Hz, 1.20 Hz, and within a range from 1.3 Hz to 1.8 Hz. There were no detected ULF suppression incidents. The strong infrasonic resonant harmonic frequency appears to be associated with deep crustal stress in Baja California, Mexico, and further north into Southern California. There was a scattering of infrasonic activity between 18:00 and 23:00 UTC, which was associated with a seismic swarm epicentered north of Yucca Valley, CA. which may be related to the high crustal stress along the Pacific & North American Plate Boundary. Tonight's seismic activity in Central California near Avenal (east of Parkfield) appears to be related to this same high crustal stress now occurring to the southeast along the Mojave Desert Block. Late in the reporting period, I observed a strong MT pulsation (10.00) for a micro quake epicentered 8 miles northwest of Parkfield, CA along the plate boundary in Central California. Regarding the recent landslide at Laguna Beach, CA, I recently read a newspaper article about a geologist who stated shortly after the last deadly mudslide in Ventura County, that if we were to have a strong earthquake, that it would trigger many similar landslides throughout Southern California because of all the record rainfall. So, if you are living in an area prone to hillside slope failure you should be prepared to move to a safer place after a felt strong earthquake.

Statement Summary:
It is inferred that the strong infrasonics are related to a rise in deep crustal stress along the Pacific & North American Plate Boundary in Southern California. The current infrasonics are inferred to be associated with high crustal stress along the San Andreas fault zone from Southern California to Central California and may also now be affecting the Owens Valley from Bishop to Coso Junction, CA as it nucleates north, and outside of the Mojave Desert Block, and west along the Garlock fault zone into the Central California Coastal region near San Simeon, CA (Pine Mountain-Big Pine faults). Also, appears to be affecting crustal stress levels as far north as The San Francisco Bay area. The San Jacinto fault zone and the Anza Seismic Gap was the focus of some of the most recently detected anomalies. We may now potentially be within 30 days of the next strong seismic event epicentered in Southern California. So, continue to stay on alert.

Note: The San Jacinto Fault Alert along with Inland Empire advisory continues to stay in effect. There was moderate infrasonic harmonic resonant activity below 2 Hz on Thursday. The Peak (Crustal) Infrasonic Harmonic Resonant Frequency was measured at 1.85 Hz (-73.23 dBv). The ULF and MT activity level was low to moderate during the past 24 hours. The inferred mean average unclamping level was higher. The ULF mean average was increased (positive). The MT peak reading was measured at 9.1 units of regional lithospheric stress. The MT mean average was measured at 8.4 units.

All daily charts were updated to reflect the latest analysis.

General Discussion:
Infrasonic resonant harmonic activity was active during the past 24 hours. There was peak activity at 0.94 Hz, and 1.85 Hz. There were no detected ULF suppression incidents. The moderate infrasonic resonant harmonic frequency appears to be associated with deep crustal stress in Baja California, Mexico, and further north into Southern California. Today's seismic swarm activity epicentered in Central California appears to now be related to high levels of deep crustal stress occurring to the southeast along the Mojave Desert Block.

Statement Summary:
It is inferred that the strong infrasonics are related to a rise in deep crustal stress along the Pacific & North American Plate Boundary in Southern California. The current infrasonics are inferred to be associated with high crustal stress along the San Andreas fault zone from Southern California to Central California and may also now be affecting the Owens Valley from Bishop to Coso Junction, CA as it nucleates north, and outside of the Mojave Desert Block, and west along the Garlock fault zone into the Central California Coastal region near San Simeon, CA (Pine Mountain-Big Pine faults).

MT ULF UPDATE: June 3, 2005

Note: The San Jacinto Fault Alert along with Inland Empire advisory continues to stay in effect. There was strong infrasonic harmonic resonant activity below 2 Hz on Friday. The Peak (Crustal) Infrasonic Harmonic Resonant Frequency was measured at 0.88 Hz (-68.35 dBv). The ULF and MT activity level was low to moderate during the past 24 hours. The inferred mean average unclamping level was higher. The ULF mean average was increased (positive). The MT peak reading was measured at 9.3 units of regional lithospheric stress. The MT mean average was measured at 8.2 units.

All daily charts were updated to reflect the latest analysis.

General Discussion:
Infrasonic resonant (fundamental) harmonic activity was active during the past 24 hours. There was peak activity at 0.84 to 0.92 Hz. There were no detected ULF suppression incidents. The moderate amplitude infrasonic resonant frequencies appear to be associated with deep crustal stress in Baja California, Mexico, and further north into Southern California along the plate boundary.

Statement Summary:
It's inferred that the strong infrasonic resonant frequencies are related to a general rise in deep crustal stress along the Pacific & North American Plate Boundary in Baja, and Southern California. The current infrasonic harmonics are associated with high crustal stress along the San Andreas fault zone( Mojave Desert Block) from Southern to Central California, that may also affect the Southern Owens Valley as it nucleates north, and west along the Garlock fault zone towards the Central California Coastal region near San Simeon, CA (Pine Mountain-Big Pine faults). Also, appears to be affecting crustal stress levels as far north as San Francisco Bay, and most recently within Central California near Avenal and Parkfield, CA. We may now potentially be within 20 to 30 days of the next strong seismic event epicentered in the Southern California region. The next New Moon will arrive on June 6, 2005. So, continue to stay on alert.

General Discussion:
Infrasonic resonant (fundamental) harmonic activity was active during the past 24 hours. There was peak activity at 1.50 to 1.66 Hz. The moderate amplitude infrasonic resonant frequencies appear to be associated with deep crustal stress in Baja California, Mexico, and further north into Southern California along the plate boundary. the latest observations were related to the border region where I detected an overnight increase in MT precursor activity related to micro quakes near Borrego Springs, Ocotillo, and Mexicali, Mexico.

Statement Summary:
It's inferred that the strong infrasonic resonant frequencies are related to a general rise in deep crustal stress along the Pacific & North American Plate Boundary in Baja, and Southern California. The current infrasonic harmonics are associated with high crustal stress along the San Andreas fault zone( Mojave Desert Block) from Southern to Central California, that may also affect the Southern Owens Valley as it nucleates north, and west along the Garlock fault zone towards the Central California Coastal region near San Simeon, CA (Pine Mountain-Big Pine faults). Also, appears to be affecting crustal stress levels as far north as San Francisco Bay, and most recently within Central California near Avenal and Parkfield, CA. The latest observations are indicating that crustal stress is also high in Northern Baja, Californa, Mexico. We may now potentially be within 20 to 30 days of the next strong seismic event epicentered in the Southern California region. The New Moon arrives on June 6, 2005. So, continue to stay on alert.

MT ULF UPDATE: June 6, 2005

Note: The San Jacinto Fault Alert along with Inland Empire advisory continues to stay in effect. There was strong infrasonic harmonic resonant activity below 2 Hz on Monday. The Peak (Crustal) Infrasonic Harmonic Resonant Frequency was measured at 0.79 Hz (-68.75 dBv). The ULF and MT activity level was low to moderate during the past 24 hours. The inferred mean average unclamping level was slightly lower. The ULF mean average was decreased (negative). The MT peak reading was measured at 8.7 units of regional lithospheric stress. The MT mean average was measured at 8.2 units.

All daily charts were updated to reflect the latest analysis.

General Discussion:
Infrasonic resonant (fundamental) harmonic activity was strong and active during the past 24 hours. There was peak activity at 0.79 Hz. The moderate amplitude infrasonic resonant frequencies appear to be associated with deep crustal stress in Baja California, Mexico, and further north into Southern California along the plate boundary. the latest observations were related to an inferred increased level of in the nucleation of deep crustal stress out of the Mojave Desert Block / ECSZ near Ludlow, CA, which is apparently also affecting the high crustal stress zone in South-Central California near the Tehachapi / Grapevine region from Taft to Frazier Park, CA. A revised alert was issued which was based upon this latest observation. There was also an observed high frequency ULF signal burst at the time of the inferred nucleation incident, indicating that deep crustal energy is now rising towards the surface in the ECSZ.

Statement Summary:
It's inferred that the strong infrasonic resonant frequencies are related to a general rise in deep crustal stress along the Pacific & North American Plate Boundary in Baja, and Southern California. The current infrasonic harmonics are associated with high crustal stress along the San Andreas fault zone( Mojave Desert Block) from Southern to Central California, that may also affect the Southern Owens Valley as it nucleates north, and west along the Garlock fault zone towards the Central California Coastal region near San Simeon, CA (Pine Mountain-Big Pine faults). Also, appears to be affecting crustal stress levels as far north as San Francisco Bay, and most recently within Central California near Avenal and Parkfield, CA.

MT ULF UPDATE: June 7, 2005

Note: The San Jacinto Fault Alert along with Inland Empire advisory continues to stay in effect. There was moderate infrasonic harmonic resonant activity below 2 Hz on Tuesday. The Peak (Crustal) Infrasonic Harmonic Resonant Frequency was measured at 0.156 Hz (-71.84 dBv). The ULF and MT activity level was low to moderate during the past 24 hours. The inferred mean average unclamping level was unchanged. The ULF mean average was basically unchanged. The MT peak reading was measured at 8.8 units of regional lithospheric stress. The MT mean average was measured at 8.1 units.

All daily charts were updated to reflect the latest analysis.

General Discussion:
Infrasonic resonant (fundamental) harmonic activity was moderate in activity during the past 24 hours. There was peak activity at 0.156 Hz. The moderate amplitude infrasonic resonant frequencies appear to be associated with deep crustal stress along the plate boundary. There were a couple more micro quakes epicentered close to the location near Ludlow where I inferred that a nucleation of crustal stress had taken place from out of the ECSZ / Mojave Desert Block, which apparently is also affecting the high crustal stress point in South-Central California near the Tehachapi / Grapevine region, and Taft to Frazier Park, CA. The level of MT related piezomagnetic activity was moderate with some indications that it was also associated with the Mojave Desert Block/ ECSZ. and we need to stay on alert as this situation continues into mid-week.

Statement Summary:
It's inferred that the strong infrasonic resonant frequencies are related to a general rise in deep crustal stress along the Pacific & North American Plate Boundary in Baja, and Southern California. The current infrasonic harmonics are associated with high crustal stress along the San Andreas fault zone( Mojave Desert Block) from Southern to Central California, that may also affect the Southern Owens Valley as it nucleates north, and west along the Garlock fault zone towards the Central California Coastal region near San Simeon, CA (Pine Mountain-Big Pine faults). Also, appears to be affecting crustal stress levels as far north as San Francisco Bay, and most recently within Central California near Avenal and Parkfield, CA. The latest observations are indicating that crustal stress is also high in Northern Baja, Californa, Mexico. We may now potentially be within 15 to 25 days of the next strong seismic event epicentered in the Southern California region.

General Discussion:
Infrasonic resonant (fundamental) harmonic activity was moderate in activity during the past 24 hours. Yesterday's peak activity at 0.156 Hz appears to be related to the strongest eruption in the past twenty years at the Colima Volcano in Cental Mexico. Also, this is the second time in recent days that this particular frequency has increased in its amplitude just prior to a strong eruption at the Colima volcano. Yesterday's nucleation of crustal stress out of the ECSZ / Mojave Desert Block, manisfested itself in a couple of micro quake along the Central Garlock Fault Zone near Randsburg, CA. That particular period of time was also accompanied by a series of infrasonic pulses during the late afternoon period and just prior to 5PM local time. The level of MT related piezomagnetic activity was also moderate to strong with some indications that it was also associated with the Mojave Desert Block/ ECSZ. We need to stay on alert as this situation continues into mid-week.

Statement Summary:
It's inferred that the strong infrasonic resonant frequencies are related to a general rise in deep crustal stress along the Pacific & North American Plate Boundary in Baja, and Southern California. The current infrasonic harmonics are associated with high crustal stress along the San Andreas fault zone( Mojave Desert Block) from Southern to Central California, that may also affect the Southern Owens Valley as it nucleates north, and west along the Garlock fault zone towards the Central California Coastal region near San Simeon, CA (Pine Mountain-Big Pine faults). Also, appears to be affecting crustal stress levels as far north as San Francisco Bay, and most recently within Central California near Avenal and Parkfield, CA. The latest observations are indicating that crustal stress is also high in Northern Baja, Californa, Mexico. We may now potentially be within 20 days of the next strong seismic event epicentered in the Southern California region.

MT ULF UPDATE: June 9, 2005

Note: The San Jacinto Fault Alert along with Inland Empire advisory continues to stay in effect. There was moderate infrasonic harmonic resonant activity below 2 Hz on Thursday. The Peak (Crustal) Infrasonic Harmonic Resonant Frequency was measured at 1.20 Hz (-70.00 dBv). The ULF and MT activity level was low to moderate during the past 24 hours. The inferred mean average unclamping level was unchanged. The ULF mean average was decreased (negative). The MT peak reading was measured at 8.6 units of regional lithospheric stress. The MT mean average was measured at 8.0 units.

All daily charts were updated to reflect the latest analysis.

General Discussion:
Infrasonic resonant (fundamental) harmonic activity was moderate in activity during the past 24 hours. As the result of an in depth re-analysis, I'm revising the inferred location for a series of strong infrasonic pulsations to be coming from within the Inland Empire instead of the ECSZ and the Garlock fault zone. The series of strong pulsations are indicating that deep crustal stress over the past 72 hours has increased along the San Jacinto fault zone near Colton, Beaumont, and Idyllwild, CA. Also, the Anza Seismic Gap may also be involved in this significant increase in deep harmonic activity from the San Jacinto fault in the Inland Empire. So, keep on an alert status until further notice.

Statement Summary:
It's inferred that the strong infrasonic resonant frequencies are related to a general rise in deep crustal stress along the Pacific & North American Plate Boundary in Baja, and Southern California. The current infrasonic harmonics are associated with high crustal stress along the San Andreas fault zone( Mojave Desert Block) from Southern to Central California, that may also affect the Southern Owens Valley as it nucleates north, and west along the Garlock fault zone towards the Central California Coastal region near San Simeon, CA (Pine Mountain-Big Pine faults).

All daily charts were updated to reflect the latest analysis.

General Discussion:
On Friday, there was one period with strong fundamental Infrasonic Harmonic Frequency activity from between 5:00PM and 8:00PM local time, which appears to be related to a micro quake epicentered in the Pine Mountain-Mettler Region of South-Central California. Earlier, I observed a typical scattering pattern of the infrasonic wave activity prior to a micro quake epicentered several miles north of Yucca Valley, CA (ECSZ).

Statement Summary:
It's inferred that the strong infrasonic resonant frequencies are related to a general rise in deep crustal stress along the Pacific & North American Plate Boundary in Baja, and Southern California. The current infrasonic harmonics are associated with high crustal stress along the San Andreas fault zone( Mojave Desert Block) from Southern to Central California, that may also affect the Southern Owens Valley as it nucleates north, and west along the Garlock fault zone towards the Central California Coastal region near San Simeon, CA (Pine Mountain-Big Pine faults). Also, appears to be affecting crustal stress levels as far north as San Francisco Bay, and most recently within Central California near Avenal and Parkfield, CA. The latest observations are indicating that crustal stress is also high in Northern Baja, Californa, Mexico. We may now potentially be within 3 weeks of the next strong seismic event epicentered in the Southern California region. There is a greater propensity for an event of this magnitude during an upcoming extremely low transit of the Full Moon, where it won't even become visible above the horizon at Fairbanks, Alaska. The low path of the Full Moon is also going to give us some unusually high spring tides at mid-latitudes during Perigee. So, that could be the catalyst for triggering an area which is known to be overdue for having its next major earthquake. Note: Perigee arrives 32 hours after the next Full Moon, which is on June 21st.

MT ULF UPDATE: June 12, 2005

Note: The San Jacinto Fault Alert along with Inland Empire advisory continues to stay in effect. There was moderate infrasonic harmonic resonant activity below 2 Hz on Sunday. The Peak (Crustal) Infrasonic Harmonic Resonant Frequency was measured at 1.28 Hz (-70.24 dBv). The ULF and MT activity level was low to moderate during the past 24 hours. The inferred mean average unclamping level was slightly higher. The ULF mean average was basically unchanged. The MT peak reading was measured at 8.7 units of regional lithospheric stress. The MT mean average was measured at 8.0 units. There was a geomagnetic transient excursion which was detected early in the period that caused a geomagnetic storm which peaked during a period with high seismic activity in Southern California.

All daily charts were updated to reflect the latest analysis.

General Discussion:
On Sunday, there was a moderate earthquake epicentered within the Anza Seismic Gap near Anza, California. It appears that the trigger for this already high crustal stress zone was a transient geomagnetic excursion that was detected early in the reporting period. The ensuing geomagnetic storm peaked out just prior to its switch into negative bz territory. The storm appears to have caused enough of a stress increase along the San Jacinto fault zone to have caused a M5.6 seismic event. If not for the storm, the area would have been delayed for a while longer. There was very little change detected after the M5.6 and the situation appears to be the same at last check. The danger comes next when the high spring tides arrive during the next Full Moon and Perigee, 32 hours later. The area from South-Central to Southern California should remain on alert for a chance that another geomagnetic disturbance could change the time schedule again, as it did on Sunday. One interesting factor was that infrasonic resonant harmonics were quite active for several hours prior to the Anza Earthquake, also indicating that the region was already under high lithospheric stress prior to the arrival of the trigger mechanism. Crustal stress now appears to have nucleated further northwest towards the Cajon Pass. The Riverside to Lytle Creek Seismic Gap should be considered at high risk, according to the infrasonics. The Inland Empire should now be on Full Alert at this time. Maybe it would be an excellent idea to schedule an earthquake drill at work or at school. We definitely are in the middle of something happening at both the north and south ends of the San Bernardino Valley region. Other faults which need to be monitored are the Southern San Andreas, Helendale, Eastern Sierra Madre-Cucamonga, Rialto-Colton, Banning, and the entire San Jacinto fault zone should now be at the focus of this short term alert.

Epilog:
Begining on June 6, 2005 until June 9, 2005 I detected a series of high amplitude infrasonic resonant harmonic pulsations that were from three specific areas in the Inland Empire. Colton, Beaumont, and Idyllwild were the specific targets of a similar infrasonic disturbance, which peaked out just prior to the June 9, 2005 M3.1 earthquake at Anza, CA. I immediately stepped up my analysis of all anomalies. My conclusion as published on June 10, 2005 was that the San Jacinto fault was at an immediate high risk for having a major earthquake within the next three weeks, and included the Anza Seismic Gap as the inferred to be at high risk epicentric location.

All daily charts were updated to reflect the latest analysis.

General Discussion:
On Monday, There was a ULF suppression incident which was associated with a M2.8 micro quake epicentered near Anza, CA. There was a moerate strength infrasonic harmonic (1.28 Hz) which appeared to be associated with the Northern Mojave Desert Block. The danger comes next when the high spring tides arrive during the next Full Moon and Perigee, 32 hours later. as it did last Sunday. Crustal stress now appears to have nucleated further northwest towards the Cajon Pass. The quiescent Riverside to Lytle Creek Seismic Gap should be considered at high risk, according to the infrasonics. The Inland Empire should now be on Full Alert at this time. Maybe it would be an excellent idea to schedule an earthquake drill at work or at school. We definitely are in the middle of something happening at both the north and south ends of the San Bernardino Valley region. Other faults which need to be monitored are the Southern San Andreas, Helendale, Eastern Sierra Madre-Cucamonga, Rialto-Colton, Banning, and the entire San Jacinto fault zone should now be at the focus of this short term alert. Activity associated with the Northern Mojave Desert Block and the Garlock Fault appears to have nucleated west to the Frazier Park region, where there was a M2.6 micro quake that was epicentered close to the San Andreas Fault at the Grapevine and Wheeler Ridge. That is another area which is at high risk during the next two to three weeks, as we approach some of the highest tides of the year during a Full Moon.

Statement Summary:
It's inferred that the strong infrasonic resonant frequencies are related to a general rise in deep crustal stress along the Pacific & North American Plate Boundary in Baja, and Southern California. The current infrasonic harmonics are associated with high crustal stress along the San Andreas fault zone( Mojave Desert Block) from Southern to Central California, that may also affect the Southern Owens Valley as it nucleates north, and west along the Garlock fault zone towards the Central California Coastal region near San Simeon, CA (Pine Mountain-Big Pine faults). Also, appears to be affecting crustal stress levels as far north as San Francisco Bay, and most recently within Central California near Avenal and Parkfield, CA. The latest observations are indicating that crustal stress is also high in Northern Baja, Californa, Mexico. We may now potentially be within 3 weeks of the next strong seismic event epicentered in the Southern California region. There is a greater propensity for an event of this magnitude during an upcoming extremely low transit of the Full Moon, where it won't even become visible above the horizon at Fairbanks, Alaska. The low path of the Full Moon is also going to give us some unusually high spring tides at mid-latitudes during Perigee. So, that could be the catalyst for triggering an area which is known to be overdue for having its next major earthquake. Note: Perigee arrives 32 hours after the next Full Moon, which is on June 21st. The area from South-Central to Southern California should remain on alert for a chance that another severe geomagnetic disturbance could trigger yet another moderate to strong seismic event.

Note: The San Jacinto Fault Alert along with Inland Empire advisory continues to stay in effect. There was moderate infrasonic harmonic resonant activity below 2 Hz on Tuesday. The Peak (Crustal) Infrasonic Harmonic Resonant Frequency was measured at 1.11 Hz (-70.04 dBv). The ULF and MT activity level was moderate during the past 24 hours. The inferred mean average unclamping level was higher. The ULF mean average was basically decreased (negative). The MT peak reading was measured at 11.2 units of regional lithospheric stress, and was the highest recorded reading since November 28, 2004. The MT mean average was measured at 8.1 units. There was a double piezomagnetic burst at approximately 13:00 UTC, which was simultaneous with the MT Peak reading. Infrasonic activity was extremly active during the second half of the reporting period.

All daily charts were updated to reflect the latest analysis.

General Discussion:
On Tuesday, There were no detected ULF Suppression Incidents. However, there was a moderate strength infrasonic harmonic (1.11 Hz) which appeared to be associated with the Southern Mojave Desert Block. There were two separate periods with a series of detected infrasonic pulsations which were observed from along the plate boundary. Some beginning prior to the M7.0 earthquake epicentered in Northern California. The high intensity of infrasonics being detected at the time of the major earthquake may have also been associated with an inferred extremely high level of deep crustal resonant energy now in place along the Pacific & North American Plate Boundary in Northern, Central, and Southern California. The coming Full Moon related high Spring Tides at Perigee should prove to be quite interesting as they affect what's already stressed to the maximum. Also, any kind of solar induced CME arrival can dramatically increase the stress level within a short period of time. I suggest we take the next several days quite seriously, and prepare for a potential major earthquake epicentered in Southern California. As far as the M3.9 at the Geysers in Northern California, I detected a long period with a high frequency ULF burst, which began at the same time as the earthquake epicentered at ClearLake, CA. Evidently, a nucleation of deep crustal stress had taken place, which affected the Geysers Geothermal Field located in Northern California (Content Expanded and Revised on June 15, 2005).

Statement Summary:
It's inferred that the strong infrasonic resonant frequencies are related to a general rise in deep crustal stress along the Pacific & North American Plate Boundary in Baja, and Southern California. The current infrasonic harmonics are associated with high crustal stress along the San Andreas fault zone( Mojave Desert Block) from Southern to Central California, that may also affect the Southern Owens Valley as it nucleates north, and west along the Garlock fault zone towards the Central California Coastal region near San Simeon, CA (Pine Mountain-Big Pine faults).

General Discussion:
On Wednesday, There was a period with ULF Suppression. There was a moderate strength infrasonic harmonic (1.15 Hz) which appeared to be associated with the Southern Mojave Desert Block. There was a late period with intense infrasonic activity associated with a small offshore earthquake epicentered near Petrolia, in Northern California. One small infrasonic pulsation was observed a few hours prior to it.

Statement Summary:
It's inferred that the strong infrasonic resonant frequencies are related to a general rise in deep crustal stress along the Pacific & North American Plate Boundary in Baja, and Southern California. The current infrasonic harmonics are associated with high crustal stress along the San Andreas fault zone( Mojave Desert Block) from Southern to Central California, that may also affect the Southern Owens Valley as it nucleates north, and west along the Garlock fault zone towards the Central California Coastal region near San Simeon, CA (Pine Mountain-Big Pine faults).

Note: Perigee arrives 32 hours after the next Full Moon, which is on June 21st. The area from South-Central to Southern California should remain on alert for a chance that another severe geomagnetic disturbance could trigger yet another moderate to strong seismic event.

MT ULF UPDATE: June 16, 2005

Note: The San Jacinto Fault Alert along with Inland Empire advisory continues to stay in effect. There was moderate infrasonic harmonic resonant activity below 2 Hz on Thursday. The Peak (Crustal) Infrasonic Harmonic Resonant Frequency was measured at 1.42 Hz (-71.53 dBv). The ULF and MT activity level was low to moderate during the past 24 hours. The inferred mean average unclamping level was lower. The MT mean average was measured at 8.4 units. The MT Peak Reading was 8.9 Units of regional lithospheric stress.

General Discussion:
On Thursday, There was a period with ULF Suppression. There was a moderate strength infrasonic harmonics (0.15 Hz, 0.94 Hz, and in a band from 1.16 to 1.60 Hz). There was an afternoon period with intense infrasonic activity associated with a moderate magnitude earthquake epicentered at Yucaipa, in Southern California. Several related infrasonic pulsations was observed. I'm also keeping an eye on the increase in seismic activity to the north of the Mojave Desert Block at Ridgecrest, CA. A special report is now in the works regarding this incident.

Statement Summary:
It's inferred that the strong infrasonic resonant frequencies are related to a general rise in deep crustal stress along the Pacific & North American Plate Boundary in Baja, and Southern California. The current infrasonic harmonics are associated with high crustal stress along the San Andreas fault zone( Mojave Desert Block) from Southern to Central California, that may also affect the Southern Owens Valley as it nucleates north, and west along the Garlock fault zone towards the Central California Coastal region near San Simeon, CA (Pine Mountain-Big Pine faults). Also, appears to be affecting crustal stress levels as far north as San Francisco Bay, and most recently within Central California near Avenal and Parkfield, CA. The latest observations are indicating that crustal stress is also high in Northern Baja, Californa, Mexico. We may now potentially be within 3 weeks of the next strong seismic event epicentered in the Southern California region. There is a greater propensity for an event of this magnitude during an upcoming extremely low transit of the Full Moon, where it won't even become visible above the horizon at Fairbanks, Alaska. The low path of the Full Moon is also going to give us some unusually high spring tides at mid-latitudes during Perigee. So, that could be the catalyst for triggering an area which is known to be overdue for having its next major earthquake. Note: Perigee arrives 32 hours after the next Full Moon, which is on June 21st.

General Discussion:
Thursday evening, There was a period with sub-ionospheric induced ULF Suppression beginning less than 2 hours prior to the M6.7 epicentered in Northern California. There were a few sporadic infrasonic pulsations detected, and inferred to be coming from the Borrego Springs and Ocotillo Wells region of Southern California. As reported yesterday, A nucleation of deep crustal stress out of the ECSZ was headed towards the Garlock fault zone, and into the Southern Sierras between Coso and Lake Isabella, CA.

On Friday, I detected two large geomagnetic excursions (spikes) which were related to two separate micro quakes epicentered north of Walker Pass, Southern Sierras. Special reports regarding this incident, Yucaipa's M4.9, and the M6.7 epicentered in Northern California are still in the process of being edited for release. Generally, recently detected Infrasonic Harmonic Crustal Resonant Frequency activity appears to have went deep again, which means that the crustal stess is festering at depth along the Pacific & North American Plate boundary. So, other parameters such as the piezomagnetic (MT), ULF, and Geomagnetic Anomalies are going to become quite important to keeping track of when it begins to surface here again and affect the secondary faults. However, it's a very short reprieve that also indicates another buildup is in progress. Meanwhile, theres a run on disaster preparation supplies. The word on the streets is, "to expect a larger earthquake than what we've so far experienced."
