*****************************
1. 13:30-13:45
TITLE: Mechanism of interseismic subsidence of the Northeast Japan forearc
during the late period of a gigantic earthquake cycle
AUTHOR: *Ryohei SASAJIMA(Kyoto University),
Bunichiro SHIBAZAKI(Building Research Institute), Hikaru IWAMORI,
Takuya NISHIMURA(Kyoto University) and Yoshihiko NAKAI(Building Research Institute)
SUMMARY: We present the mechanism of the observed subsidence of
the Northeast Japan forearc during ~100 years before the 2011 Tohoku earthquake.

2. 13:45-14:00
TITLE: The 2015 Gorkha earthquake: earthquake reflection imaging of
the source fault and connecting seismic structure with fault slip behavior
AUTHOR: *Eiji KURASHIMO, Hiroshi SATO, Shin’ichi SAKAI, Naoshi HIRATA,
Ananta Prasad GAJUREL･Danda Pani ADHIKARI(Tribhuvan University),
Krishna Prasad SUBEDI (NAST), Hiroshi YAGI(Yamagata University) and
Bishal Nath UPRETI (NAST)

3. 14:00-14:15
TITLE: Stress change before and after the 2011 M9 Tohoku-oki earthquake
AUTHOR: Thorsten W. BECKER(The University of Texas at Austin), *Akinori HASHIMA,
Andrew M. FREED(Purdue University) and Hiroshi SATO
SUMMARY: We show that the F-net moment tensor catalog indicates systematic changes
in crustal stress in the years leading up to the 2011 M9 Tohoku-oki earthquake,
due to the co-seismic effect, and for the last few years due to viscous relaxation.
