This animation shows the 9.0
This animation shows the 9.0 magnitude earthquake that struck off the coast of Japan's Tōhoku-Oki region on 11 March 2011 and the first six months of its aftershocks.
For animations of the resulting tsunami, please see:
"flat earth" (Mercator) - Tsunami Animation: Tohoku, Japan 201...
"rotating globe" - Tsunami Animation: Tohoku, Japan 201...
This sequence will allow you to compare the more typical background level of seismic activity in Japan with the elevated levels of activity resulting from the great earthquake and its aftershocks. You will also be able to see the size and shape of the "rupture zone"--the portion of the fault that moved during the great earthquake--as revealed by the cluster of aftershocks. Also look for the 7.2 magnitude foreshock that preceded the 9.0 magnitude mainshock two days earlier on March 9.
