The 2011 off the Pacific coast of Tohoku Earthquake: Coseismic Slip Distribution Model
Crustal Deformation and Fault Model obtained from GEONET data analysis
Crustal Deformation and Fault Model
We constructed a distributed slip model using coseismic surface displacement data observed by the GPS Earth Observation Network System (GEONET) for the 2011 off the Pacific coast of Tohoku Earthquake. The vertical displacement calculated using our slip model suggests that large subsidence occurs along the Pacific coast.
GSI manually collected GPS data which were unavailable due to the suspension of a data transmission system just after the earthquake. We used these data to revise the preliminary model presented on March 14, 2011.
