Seafloor observations indicate spatial separation of coseismic and postseismic slips in the 2011 Tohoku earthquake

Abstract

Postseismic slip of the 2011 Tohoku earthquake in Japan has occurred on the plate interface, but quantifying the slip has been difficult due to a lack of seafloor data. Here, the authors use seafloor and terrestrial data and show that areas of co- and postseismic slip are spatially separated.
