Rupture zone of the 2013 Sea of Okhotsk quake mapped in pink; each ring inside the outline represents 2.2 meters of slip. Blue dots are aftershocks, each about magnitude 4. Large round symbols show the orientation of the slip motion for the 8.3 quake and two earlier earthquakes in 2008. Dashed contour lines show the top of the subducting Pacific plate. Arrows show the motion of the rock during the rupture. The land on the east is the west coast of the Kamchatka Peninsula.
