Fig. 4.From: Centroid-moment-tensor analysis of the 2011 off the Pacific coast of Tohoku Earthquake and its larger foreshocks and aftershocksMaps showing (left) focal mechanisms of the mainshock and conforming aftershocks, and (right) non-conforming aftershocks. The focal mechanisms are plotted at the centroid locations, and their size is proportional to the moment magnitude. Yellow hexagon in left map shows mainshock epicenter. Plate boundaries are from Bird (2003).Back to article page
