Volcanic Cone Collapses and Tsunamis

  • An unstable volcano is a potential source for a Tsunami.

  • Weakened and fractured material may give way and cause a collapse.

  • The most common cause is intrusion of magma, which causes a detachment.

  • Injection of magma into the interior of the volcano causes the volcanic cones to inflate, and the magma pushes out part of the volcano. Magma filling steep faults and fractures can provide a lubricated surface along which collapse may take place. The pore pressure within a volcano may increase owing to the presence of intruding magma, the volcano being squeezed by geological (tectonic) stresses; extra water within the volcano caused by increased rainfall, or a change in the local drainage system.

  • Earthquakes that "shake" the volcano.

  • Weakening of the volcano caused by heat and hot fluids in the interior of the volcano that alter hard volcanic rocks into soft clay.

  • Slippage along the surface on which the volcano is built, caused by a low-angle fault or lubricants such as clays or injected magma.

  • The volcano becomes too steep and high, regular volcanic eruptions pile more and more volcanic materials onto the upper slopes of the volcano which then is susceptible to collapse through gravity.

    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.

    On Wednesday, significant Piezomagnetic activity was observed and inferred to be associated with the Western Garlock fault zone near Mojave, CA. The ULF and MT activity observed during the period of yesterday's eruption at Mount Saint Helens was nomimal. It's rare to observe an anomaly during an actual event. It usually occurs over a period of days leading up to either an earthquake or volcanic eruption. However, there may be residual stress changes now taking place, including that which was observed for the recent offshore moderate seismic activity that preceded the eruption. The other factor is the change to an extremely low peak frequency infrasonic harmonic when compared to recent observations. The lowest frequencies are inferred to be associated with an increase in deep crustal stress along the Pacific and North American Plate Boundary.

    Currently, there is another observed burst in piezomagnetic activity that appears to be associated with the predicted high Spring-tides, which are now in effect.

    MT ULF UPDATE: March 11, 2005

    Note: The San Jacinto Fault Alert along with Inland Empire advisory continues to stay in effect. There was no detected infrasonic resonant harmonic activity below 2 Hz on Friday. The ULF and MT activity level was moderate during the past 24 hours. The inferred mean average unclamping level was unchanged during the past 24 hours. The ULF mean average significantly decreased (negative) for the fourth consecutive day. All daily charts were updated to reflect the latest analysis.

    The most recent ULF activity appears to be associated with the Northern California Coast and includes a long period with detected pulsed ULF signal burst activity. ULF activity significantly increased during the evening hours and appears to have significantly increased after a micro quake epicentered near Petrolia, CA. The offshore and coastal region should now be under an advisory. Previous areas with precursor ULF signal burst activity with pulsations was the Adobe Hills Volcanic field, east of Mono basin and the Long Valley Caldera (Mammoth Lakes, CA) just prior to a vigorous seismic swarm. The recently observed increase in Piezomagnetic activity from along the Garlock Fault Zone may have been an indication of a stress nucleation event out of the ECSZ /Mojave Desrt Block and into the Eastern Sierras and the Central California Coastal region. Infrasonic Harmonic activity was also increasing along with a change towards having several large spikes in harmonic content. The disturbance in infrasonic activity appears to be associated with the Pacific and North American Plate boundary. Within 48 hours after I reported a signifcant change in having an unusually low frequency resonant infrasonic harmonic at 0.17 Hz there was a notable eruption at the Colima Volcano, Mexico.

    MT ULF UPDATE: March 12, 2005

    Note: The San Jacinto Fault Alert along with Inland Empire advisory continues to stay in effect. There was infrasonic resonant harmonic activity below 2 Hz on Saturday. The Peak (Crustal) Infrasonic Resonant Harmonic Frequency was measured at 1.43 Hz (-72.82 dBv). The ULF and MT activity level was moderate during the past 24 hours.

    A long period with detected pulsed ULF signal burst activity continued during Saturday. Increased ULF activity is apparently related to current stress changes along the Pacific and North American plate boundary in Southern California. So the region from the Salton Sea to the Cajon Pass along the San Andreas fault needs to be prepared just in case this long period of ULF pulsation is a precursor to another earthquake.

    A long period with detected pulsed ULF signal burst activity continued during Sunday. The increase in ULF activity is apparently related to a crustal stress change taking place along the Pacific and North American plate boundary in Southern California. Today's small earthquake epicentered north of Palomar Mountain appears to be related to it. Yesterday, I was concerned that deep crustal stress had nucleated out of the Gulf of California and into the region from the Salton Sea to the Cajon Pass along the plate boundary. Today's peak at 0.11 Hz in the infrasonic resonant harmonic is an indication that the tectonic stress in Mexico associated with the recent increase in volcanic unrest at Colima may be related to this increase in stress to the north. Tonight, the long duration ULF pulsations are just as vigorous as they were 24 hours ago. The infrasonic harmonic activity is ping ponging between the Gulf of California and the Long Valley Caldera according to the frequency vs. latitudes being observed. Today, there were several key frequencies related to this and centered from the Eastern Sierras to Central Mexico, with an emphasis towards the stronger harmonics being for Central Mexico to Southern California, and with lower amplitude as they ascend towards the Mammoth Lakes to Mono Lake region.

    M3.6 2005/03/14 20:23:07 UTC 34.423N 118.669W d:14.3 km ( 6 mi) WNW of Valencia, CA

    A long period with detected pulsed ULF signal burst activity continued during Monday. The increase in ULF activity is apparently related to a crustal stress change taking place along the Pacific and North American plate boundary in Southern California. Today's small earthquake epicentered north of Los Angeles, appears to be related to it. Tonight, the long duration earth-induced sub-ionospheric ULF pulsations are dissipating in intensity. The situation that appears to have taken place is another nucleation of deep crustal energy out of the ECSZ and towards the Garlock Fault/Southern Owens Valley between the Lenwood and Blackwater faults where the new plate boundary is in its early stages of formation. We can expect events of this nature from time to time as stress nucleates around the locked big bend along the San Andreas fault zone.

Note: 1.0 Hz is inferred to be the infrasonic resonant frequency for the San Andreas fault in Southern California. The ULF and MT activity level was moderate during the past 24 hours. The inferred mean average unclamping level was slightly lower during the past 24 hours. The ULF mean average slightly decreased (negative). All daily charts were updated to reflect the latest analysis.

    Tonight, the long duration earth-induced sub-ionospheric ULF pulsations are once again active for a period. It's related to crustal stress changes now taking place along the Pacific and North American plate boundary in Southern California. The wrenched and compressed ECSZ/Mojave Desert block is nucleating stress northwest along it's active strik-slip faults towards the Southern Owens Valley and the Garlock Fault zone, where a new plate boundary is in its early stages of development from east of Barstow to Little Lake, CA. Secondary earthquakes will be quite active whenever there is observed nucleation of stress. The monitoring effort is critical to forecasting whenever there is a threat of increased seismic activity in the Inland Empire, Los Angeles Basin, Santa Barbara Channel, and the Mojave Desert Block. Further north, it affects the Eastern Sierras and usually dissipates in the region near the Long Valley Caldera. Otherwise, it nucleates west along the Garlock fault zone towards Wheeler Ridge and the Central Coast of California (San Simeon) via the Big Pine fault, which is inferred to be a continuation of the Garlock Fault on the Pacific side of the plate boundary. Increasing stress along the long overdue San Jacinto fault tends to step over to the Elsinore fault where it usually nucleates northwest towards the region between Yorba Linda and Val Verde, CA. This is going to be a repeating pattern that you will become quite familiar with as the changes progress. It's a crustal stress pattern that I've studied and reported upon now for at least the past five years.

    Tonight, long duration (earth-induced) sub-ionospheric ULF pulsations are again extremely active. There is no change since the latest small earthquake epicentered near Borrego Springs, CA. Currently watching for the nucleation of crustal stress out of the border region with Northern Baja, Mexico. Increased ULF activity was observed from near Anza, and Borrego Springs (San Jacinto Fault Zone), CA. Since ULF pulsations have not decreased in intensity, I believe that the Anza Seismic Gap (San Jacinto fault) is at an extremely high crustal stress level, and it could next nucleate further north towards the Cajon Pass and the Inland Empire region, or step over towards the Elsinore fault zone. So please stay on alert!

    M3.4 2005/03/23 00:07:06 UT 33.882N 118.451W d:11.2 km ( 3 mi) W of Manhattan Beach, CA

    The previously reported long duration (earth-induced) sub-ionospheric ULF pulsations have progressed to an erratic mode along with high amplitude piezomagnetic bursts. The major change was observed shortly prior to the Santa Monica Bay M3.4 earthquake. Tonight, there was a strong piezomagnetic burst which was associated with a micro quake epicentered at Mount Saint Helens Volcano, WA. The step over of crustal stress out of the San Jacinto fault zone (Anza/Borrego Springs, CA) may have also affected the offshore region west of Santa Monica, CA. With these observed high level ULF signal bursts taking place in an even further erratic way, I think it would be best to stay on alert for the next several days as we approach the Lunar-Tidal changes associated with the next Full Moon. The most recent check for the MT reading was at a high 10.0 units of regional lithospheric stress, which is a full point higher than it was at 7:00 PM PST. (03:00 UTC).

    Several piezomagnetic bursts were detected during the past 24 hours. The strongest one (10.00 units) appeared to be associated with a micro quake epicentered at Mount Saint Helens Volcano, WA. It's interesting to note that another strong piezomagnetic burst appeared to be associated with a swarm of micro quakes epicentered in Hawaii. With the current changes now taking effect, I think it would be best to stay on alert for the next several days as we approach the Lunar-Tidal changes associated with the next Full Moon. The latst observation indicates that ULF pulsations have now ended, and I'm waiting to see if they return again.

    The latest offshore activity in Southern California appears to be related to the Full Moon Lunar-Tidal changes. Also a small seismic swarm near Borrego Springs may be related to this gravity induced change in lithospheric stress between 05:00 and 05:10 UTC, which was approximately 10 minutes after the predicted maximum high tide (4.82 ft.) at Newport Beach, CA.

    The small earthquake (M3.6) near Parkfield, CA also appears to be Lunar-tidal related. With a timing of approximately 90 minutes prior to the predicted highest tide (4.88 ft.) along the Central California coast at San Simeon.

    ULF activity was observed coming from Borrego Springs and near Yucaipa, CA. However, the activity continues at an extremely low level compared to recent past. Local Infrasonic resonant activity also is at a low level. THe ULF mean average is in a steady state of fluctuation and hasn't broken out to either higher or lower point in the past week. MT activity also is staying mostly in a range from 8.5 to 8.7 Units of regional lithospheric stress. Today I completed an analysis for the March 23, 2005 Piezomagnetic Burst , which was detected from here in Southern California.

    Note: The San Jacinto Fault Alert along with Inland Empire advisory continues to stay in effect. There was infrasonic resonant harmonic activity below 2 Hz on Monday. The Peak (Crustal) Infrasonic Resonant Harmonic Frequency was measured at 1.84 Hz (-75.42 dBv). The ULF and MT activity level was low to moderate during the past 24 hours. The inferred mean average unclamping level was lower during the past 24 hours. The ULF mean average was relatively unchanged. All daily charts were updated to reflect the latest analysis.

    Todays' important global seismic event was yet another great earthquake in the Sumatra Indonesia region, which was caused by a nucleation of stress from the Decmber 26, 2004 Mw9.2 earthquake. A small MT precursor was detected about 20 minutes prior to the main shock. A report should be ready within the next week. Otherwise the North American and Pacific Plate ULF activity was lackluster during the past 24 hours. No unclamping incidents were detected prior to the latest great earthquake. It was not unexpected that another strong earthquake would occur in the region already devastated. Mega Thrust Earthquakes usually occur in clusters(as pointed out in my recent interview on Dreamland), and related to the later stages of the current Solar cycle.

    The most significant MT activity was detected begining just prior to today's M6.4 earthquake epicentered in Northern Sumatra, Indonesia. The Piezomagnetic burst (precursor) appears to have nucleated crustal stress into the Eastern Sierras near the Long Valley Caldera. At least two micro quakes were observed to have been related to the piezomagnetic burst, which increased the level of unrest within the Volcanic Tablelands, Hilton Creek Fault, and northeast of the Long Valley Caldera's resurgent dome. The vector of this crustal stress is aligned NE along the Hilton Creek fault, which is inferred to be the location of a magma dyke intrusion that was caused by four M6.0 earthquakes that occurred in 1980, a week after the major eruption of Mount Saint Helens Volcano, WA. No one really knows what is the source of this unrest, except to say that strong Volcanic and Seismic events, including the Lander's and Hector Mine earthquakes created a definite increase in seismic activity at the caldera. The most recent eruption in the region was about 250 years ago at Mono Lake, CA. I'll have another report for this triggered unrest completed later in the week. It's important to realize that detection of this latest piezomagnetic burst is direct evidence for the theory of far-field stress triggering of both volcanic and seismic events, worldwide.

    Regarding Donations for GeoSeismic Labs

    Donations made by direct contribution are important to help keep the lab operating through the year. One item that needs emphasis is the annual operating cost related to being a public corporation within the state of California; a fee which is 800 Dollars, and paid for the privilege of being a public entity. Last fiscal year, I directly paid to the State Secretary approximately 2 Thousand Dollars in Franchise Tax Fees to keep the lab solvent and fully chartered within the State of California. Your donations will basically cover the cost of keeping the web site operating 24/7. The depth of my research is increasing exponentially as events occur and I focus upon them. My 365 days of ground-breaking reports, will keep you informed and prepared for the future.


    IMPORTANT:
    For those who elect to send a personal check or postal money order
    Please send an email request to the address listed on my website for special instructions.

    Also, All credit card funded donations using the automatic Paypal donation button will automatically be rejected unless you request easy to follow alternate instructions via email and follow them completely. Thank you,
