From: Slip distribution of the 2011 off the Pacific coast of Tohoku Earthquake inferred from geodetic data
Coseismic horizontal displacement vectors associated with the 2011 earthquake and configuration of the subducting Pacific plate used for analysis in this study. Dots inside the source region are knots of B-splines used for the slip distribution. Red triangles, blue and black squares show the ocean-bottom pressure gauges, the seafloor geodetic sites and GPS sites of GEONET, respectively.
