[SCG57-05] Aftershock observation of the 2016 Central Tottori Earthquake

*Yoshihisa Iio1, Satoshi Matsumoto2, Takashi Iidaka3, Eiji Kurashimo3, Shin'ichi Sakai3, Yusuke Yamashita1, Aftershock observation group of the 2016 Central Tottori Earthquake (1.Disater Prevention Research Institute, Kyoto University, 2.Kyushu University, 3.Earthquake Research Institute, University of Tokyo)

Keywords:stress, strength of fault, Central Tottori Earthquake, aftershock, focal mechanism

We installed a seismic observation network with 69 high-gain short period seismometers in the aftershock area of the 2016 Central Tottori Earthquake, in order to clarify the stress field and fault strength in the aftershock area. We can determine very precisely focal mechanisms using this dense seismic data.
