7.3 Earthquake Strikes Off Japan; Little Damage Reported: AIR
December 7, 2012
[snip]
Dr. Lai commented, ?The Japan Trench is one of the most seismically active subduction systems on earth. On average, more than one earthquake of magnitude 7 occurs in this 800-km long subduction zone every decade. In the last four decades alone, 12 events of M7 or larger have occurred within 250 km of today?s event. Other large historic earthquakes to have occurred here include a M8.5 event in 1896, a M8.1 event in 1933, and a M7.5 earthquake in 1915.?

?Today?s earthquake?which occurred along the subducting slab of the Japan Trench interface?is likely associated with stresses due to the ?bending or unbending? of the crust in this tectonic region and/or evolving stresses due to the earlier Tohoku event. Today?s event is also possibly associated with normal or reverse faults in the lower to middle crust, as the direction of earthquake-related plate movements reveal. The nature of today?s earthquake is rather unusual since so-called ?bending or unbending? events are rarely observed in subduction zone areas.?..
