|Effects of Subducted Seamounts on the Source Process of the 1946 Nankai Earthquake, SW Japan|
Takane Hori, Toshitaka Baba, Phil Cummins, Yoshiyuki Kaneda
We hypothesize that the complexity of the source process of the 1946 Nankai earthquake is mainly caused by the subduction of the seamounts. We carried out incremental stress field calculation for a seamount subduction using FEM. The results indicates that we may explain some of the characteristics of the source process considering the stress perturbation caused by the seamount subduction.
