    I just looked on Google Earth, and this quake occurred offshore, on the same narrow shelf as the Honshu quakes, but obviously, much further south. Is this new to this area? I know for a long time people have questioned why quakes have not been moving up and down the fault, remaining centered near Honshu. ?????????

    I know. That is the first link I check. The answer is no. This is new. It does not appear to be directly related to volcanic activity. i.e. it's on the move. I like the hybrid feature of the link, but the full application is a lot more fun. Either way, the Pacific plate is most distinct.

    LOS ANGELES (LALATE) – Today’s Japan earthquake has not prompted a tsunami advisory for the southern section of the country. A Japan earthquake struck today April 11, 2011 in a substantially different region of the country than previous earthquake activity. Most quakes have been centered off the east coast of Honshu, generally east of Yamagata, Sendai and Fukushima; they have typically been roughly three hundred miles north east of Tokyo. Today’s quake, however, struck south of Tokyo. Local news Saturday is not reporting any damages nor injuries currently.


    Shortly before 10 pm local time Saturday, the Kyushu section of Japan suffered a 6.1 magnitude earthquake. Local news reports that the quake was centered east of the Kyushu section of the country, only thirteen miles below the earth’s surface. The quake struck roughly one hundred miles south of Miyazaki and east of Kagoshima.

    The quake was roughly five hundred miles from Seoul, South Korea and six hundred miles south west of Tokyo.

    Following the quake, the Japan Meteorological Agency did not issue to news as Tsunami Warning nor Tsunami Advisory. Just last week, following the country’s powerful 7.4 magnitude quake, the Agency issued a brief “Tsunami Warning” for the Miyagi Pref. and a “Tsunami Advisory” for the Pacific Coast of Aomori Pref, Iwate, Fukushima, and Ibaraki.

    Low-frequency earthquakes in Shikoku, Japan, and their relationship to episodic tremor and slip
    David R. Shelly1, Gregory C. Beroza1, Satoshi Ide2 and Sho Nakamula3


    Top of pageNon-volcanic seismic tremor was discovered in the Nankai trough subduction zone in southwest Japan1 and subsequently identified in the Cascadia subduction zone2. In both locations, tremor is observed to coincide temporally with large, slow slip events on the plate interface downdip of the seismogenic zone2, 3, 4, 5, 6, 7. The relationship between tremor and aseismic slip remains uncertain, however, largely owing to difficulty in constraining the source depth of tremor. In southwest Japan, a high quality borehole seismic network allows identification of coherent S-wave (and sometimes P-wave) arrivals within the tremor, whose sources are classified as low-frequency earthquakes. As low-frequency earthquakes comprise at least a portion of tremor, understanding their mechanism is critical to understanding tremor as a whole. Here, we provide strong evidence that these earthquakes occur on the plate interface, coincident with the inferred zone of slow slip. The locations and characteristics of these events suggest that they are generated by shear slip during otherwise aseismic transients, rather than by fluid flow. High pore-fluid pressure in the immediate vicinity, as implied by our estimates of seismic P- and S-wave speeds, may act to promote this transient mode of failure. Low-frequency earthquakes could potentially contribute to seismic hazard forecasting by providing a new means to monitor slow slip at depth.

    Thank You Troy - Actually I WAS awake at 3 :30 Am - awakened by hail and rain and thunder and lightening - did NOT feel earth rumbling, but it was a powerful thunder and lightning and we do not usually get this - I had the thought - well we're getting the cesium and xenon raining down on us now, and the sound of the thunder and rumbling was so strange I wondered if they were doing HAARP earthquake as well. Your timestamp said 3:33 AM - - too bizarre...

    Per the report, Western Colorado is quite seismically active -

    _________________

    Prepared by the Earthquake Subcommittee
    Colorado Natural Hazards Mitigation Council


    Introduction

    Colorado is comprised of areas with low to moderate potential for damaging earthquakes, based on research by geologists and geophysicists who specialize in seismology. There are about 90 potentially active faults that have been identified in Colorado, with documented movement within the last 1.6 million years. However, there are several thousand other faults that have been mapped in Colorado that have not been sufficiently studied to know whether they are capable of generating earthquakes or not. It is not possible to accurately estimate the timing or location of future dangerous earthquakes in Colorado. The lack of an adequate network of seismometers in Colorado makes it difficult to detect and locate earthquakes. Moreover, the historical record is quite short (~150 years). Nevertheless, the available seismic hazard information can provide a basis for a reasoned and prudent approach to seismic safety.


    Faulting

    Sudden movement on faults is responsible for large earthquakes. By studying the geologic characteristics of faults, geoscientists can often determine when the fault last moved and estimate the magnitude of the earthquake that produced the last movement. In some cases, it is possible to evaluate how frequently large earthquakes occurred on a specific fault during the recent geological past.


    Geological studies in Colorado indicate that there are about 90 faults that moved during the Quaternary Period (the last 1.6 million years) and should be considered potentially active. The Sangre de Cristo Fault, which lies at the base of the Sangre de Cristo Mountains along the eastern edge of the San Luis Valley, and the Sawatch Fault, which runs along the eastern margin of the Sawatch Range, are two of the most prominent potentially active faults in Colorado. Not all of Colorado’s potentially active faults are in the mountains and some can not be seen at the earth’s surface. For example, the Cheraw Fault, which is in the Great Plains in southeast Colorado, appears to have had movement during the recent geologic past. The Derby Fault near Commerce City lies thousands of feet below the earth’s surface but has not been recognized at ground level.


    Several potentially active faults in Colorado are thought to be capable of causing earthquakes as large as magnitude 6½ to 7¼. In comparison, California has hundreds of hazardous faults, some of which can cause earthquakes of magnitude 8 or larger. The time interval between large earthquakes on faults in Colorado is generally much longer than on faults in California.


    Past and Possible Future Earthquakes

    More than 500 earthquake tremors of magnitude 2½ or higher have been recorded in Colorado since 1867. More earthquakes of magnitude 2½ to 3 probably occurred during that time, but were not recorded because of the sparse distribution of population and limited instrumental coverage in much of the state. For comparison, more than 20,500 similar-sized events have been recorded in California during the same time period. The largest known earthquake in Colorado occurred on November 7, 1882 and had an estimated magnitude of 6½. The location of this earthquake was in the northern Front Range west of Fort Collins.



    COLORADO’S LARGEST HISTORIC EARTHQUAKES

    (Records date back to 1867)

    * = magnitude estimated for older earthquake; based on historical felt reports

    Although many of Colorado’s earthquakes occurred in mountainous regions of the state, some have been located in the western valley and plateau region or east of the mountains. The most economically damaging earthquake in Colorado’s history occurred on August 9, 1967 in the northeast Denver metropolitan area. This magnitude 5.3 earthquake, which was centered near Commerce City, caused more than a million dollars damage in Denver and the northern suburbs. This earthquake is believed to have been induced by the deep injection of liquid waste into a borehole at Rocky Mountain Arsenal. It was followed by an earthquake of magnitude 5.2 three months later in November 1967. Although these events cannot be classified as major earthquakes, they should not be discounted as insignificant. They occurred within Colorado’s Front Range Urban Corridor, an area where nearly 75% of Colorado residents and many critical facilities are located. Since March 1971, well after the initial flurry of seismic activity, 15 earthquakes of approximate magnitude 2½ or larger have occurred in the vicinity of the northern Denver suburbs. At least two published articles propose that a magnitude 6.0 earthquake is possible on the Derby fault. Such an earthquake would cause more than $10 billion dollars damage.


    Relative to other western states, Colorado’s earthquake hazard is higher than Kansas or Oklahoma, but lower than Utah, and certainly much lower than Nevada and California. Even though the seismic hazard in Colorado is low to moderate, it is likely that future damaging earthquakes will occur. It is prudent to expect future earthquakes as large as magnitude 6.5, the largest event of record. Calculations based on the historical earthquake record and geological evidence of recent fault activity suggest that an earthquake of magnitude 6 or greater may be expected somewhere in Colorado every several centuries.
    Summary and Conclusions

    Based on the historical earthquake record and geologic studies in Colorado, an event of magnitude 6½ to 7¼ could occur somewhere in the state. Scientists are unable to accurately predict when the next major earthquake will occur in Colorado, only that one will occur. The major factor preventing the precise identification of the time or location of the next damaging earthquake is the limited knowledge of potentially active faults. Given Colorado’s continuing active economic growth and the accompanying expansion of population and infrastructure, it is prudent to continue the study and analysis of earthquake hazards. Existing knowledge should be used to incorporate appropriate levels of seismic safety in building codes and practices. The continued and expanded use of seismic safety provisions in critical and vulnerable structures and in emergency planning statewide is also recommended. Concurrently, we should expand earthquake monitoring, geological and geophysical research, and mitigation planning.


    The information contained herein is intended to provide general information to the public and should not be used for site-specific engineering purposes. Seismic hazard assessment for a particular location should incorporate an appropriate engineering evaluation.


    Further Published Information
    The Colorado Geological Survey has several publications on Colorado earthquakes and potentially active faults, and maintains a reference collection on Colorado seismicity that includes reports by consultants or agencies.

    Daily tremors good for Fiji
    Avinesh Gopal
    Wednesday, March 09, 2011

    TREMORS in the Fiji Group are recorded almost every day by seismologists but they're often minor to moderate in size and cannot be felt on the earth's surface.

    The epicentre of the tremors is between 400 and 500 kilometres within the earth's inner crust and most measure around three on the Richter scale.

    "It's good to have small ones like that because the energy is released from right down below," Sefanaia Seru, a seismologist with the Mineral Resources Department, said.

    "We normally record tremors every day but most are minor to moderate in size and people can't feel it on the surface because it's deep down.

    "There are actually two major active fault lines - one is above the Yasawa Group and extends to Taveuni while the other is in the South of Kadavu.

    "In reality, we can't forecast earthquakes like cyclones and even seismologists globally can't predict it - that's the major problem.

    "Only when it happens then we can tell and how frequently it happens is all a matter of timing."

    Mr Seru said Fiji was unfortunate to sit on the Pacific Ring of Fire, which includes Vanuatu and the Tonga region.

    "Because the trench where the two big tectonic plates meet is far from us, the Tonga and Vanuatu trenches are the tsunami triggering zones and if there's a tsunami from there then we in Fiji have sufficient time to be warned," he said.

    "We have active fault lines in Fiji that can generate a tsunami like in 1953 but the probability is low."

    Mr Seru said the only way people could prepare themselves from an earthquake was by strengthening buildings and reinforcing their houses.

    "For a tsunami, people in low-lying areas should have their own evacuation routes to higher ground whenever there is a warning," he said.

    The last quake last night was at 22:22:22 UTC. I saw that just as I was asking myself if once again the quakes stopped before midnight, and picked up again, later.

    Zack Covell is concerned because it is an 11/11 day, and he cannot get through to HAARP's Alaska ".edu" server.
