[H-CG37] [JJ] Active fault and disaster mitigation learned from 2016 Kumamoto earthquake

Sun. May 21, 2017 10:45 AM - 12:15 PM A02 (Tokyo Bay Makuhari Hall)

convener:Yasuhiro Suzuki(Nagoya University), Hiroyuki Fujiwara(National Research Institute for Earth Science and Disaster Prevention), Yoshiaki Hisada(Kogakuin University, School of Architecture), Toshitaka Kamai(Disaster Prevension Research Institute, Kyoto University), Chairperson:Yoshiaki Hisada(Kogakuin University, School of Architecture), Chairperson:Yasuhiro Suzuki(Nagoya University)

The 2016 Kumamoto Earthquake was a large, hazardous inland earthquake generated by the reactivation of the Futagawa-Hinagu Fault located at the center of the Kyushu province, Japan. It occurred twenty-one years after the 1995 Kobe Earthquake that prompted the Japanese government to start devising comprehensive countermeasures against the active fault. The Kumamoto Earthquake has posed many problems to the fields of seismology, active fault research, and earthquake engineering, as well as to disaster prevention strategies against active faults. This session aims to share the current interdisciplinary understanding and unsolved questions, and to discuss necessary future research paths and potential countermeasures. It covers the following subjects: earthquake damage, behavior of earthquake faults, strong ground motion, ground disaster, building code and related regulations, disaster support or recovery system, disaster education etc.
