Structural controls on the Mw 9.0 2011 Offshore-Tohoku earthquake
Joint seismic tomography exploiting P and S wave arrivals conducted before the 2011 Offshore Tohoku earthquake reveals an area comparable to the faulting surface for the 2011 March 11 event with different properties from other areas along the shallow part of the subduction zone. The differences are revealed by using a measure R of the relative variations in shear wavespeed and bulk-sound speed. Within the faulting area there are patches on the subduction zone with slightly reduced S wavespeed,...[Show more]
