Stronger 6.2 earthquake strikes off the northeast coast of Japan

November 24, 2011 TOKYO – A 6.2 magnitude earthquake struck off the northeast coast of Japan near Hokkaido. It is the second large quake to strike near the Japanese mainland in 24 hours. The depth of the earthquake was 42.3 km (26.3 miles). The epicenter of the stronger earthquake was 122 km (75 miles) SSW of Obihiro, Hokkaido, Japan and 734 km (456 miles) NNE of Tokyo, Japan. Given the location and volcanic origins of the Japanese islands- it is highly improbable that the islands could survive the massive turbulence from sudden dramatic shifts in tectonic plates along these powerful subduction drains. The Japanese islands lie in one of many dangerous Benioff seismic zones in the Pacific Ring of Fire. A Wadati–Benioff zone (also Benioff–Wadati zone or Benioff zone or Benioff seismic zone) is a deep active seismic area in a subduction zone. These dangerous zones are often lined by deep volcanic trenches. Differential motion along these zones produces deep-seated earthquakes- the foci of which may be as deep as 700 kilometers (430 mi). They develop beneath volcanic island arcs and continental margins above active subduction zones. They can be produced by slip along the subduction thrust fault or slip on faults within the subducting plate, as a result of bending and extension as the plate is dragged into the Earth’s mantle. –The Extinction Protocol  地震日本

    They just keep on getting clobbered by these things, and two in a day? I’ll have to look up the news…

    What is the latest news on Mt. Fuji? The last I remember hearing was that there was some activity after the 9.0 in March. I’m just wondering if all this recent activity is affecting it?

    I just hope that half of Japan does not sink into the ocean…

    Science Daily – November 17th
    New research, published this week in the journal Applied Physics Letters, suggests that ozone gas emitted from fracturing rocks could serve as an indicator of impending earthquakes.
