| Research Abstract |
We studied inter-, pre-, and co-seismic process of mega-quake in the Nankai subduction zone. The main topics are (A) slow deformation on the shallow plate interface around accretionary prism, (B) dynamic rupture in geometrically complex fault system, and (C) earthquake cycle including preparation stage of a mega-quake. We successfully constructed a new comprehensive model for physical processes of mega-earthquakes in subduction zone, in a wide frequency range, through the modeling of slow earthquakes and the 2011 Tohoku-Oki earthquake.
