[S-CG52] Intraslab and intraplate earthquakes

2018年5月22日(火) 10:45 〜 12:15 A03 (東京ベイ幕張ホール)

コンビーナ:北佐枝子(建築研究所)、大内智博(愛媛大学地球深部ダイナミクス研究センター)、Thomas P. Ferrand (東京大学地震研究所、共同)、岡崎啓史(海洋研究開発機構)、座長:Thomas Ferrand(ENS)、岡崎啓史(海洋研究開発機構)

The purpose of this session is to share recent advances of geo-scientifical studies for intraslab (intraplate) earthquakes. We seek to formulate future directions of the interdisciplinary study of the occurrence of intermediate-depth intraslab earthquakes from the viewpoint of seismology, geodynamics and mineral physics. We welcome presentations from a wide variety of scientific disciplines, including seismology, seismotectonics, geodynamics, mineral and rock physics, other geophysics, geology, and numerical modeling. Studies for outer-rise earthquakes, shallow-depth intraplate earthquakes and deep earthquakes are also welcomed because it is important to know the characteristics of shallow-depth intraslab earthquakes and deep earthquakes for understanding for the generation process of intermediate-depth intraslab earthquakes.
