1. 13:30-13:45<\/p>\n\n\n\n
TITLE: Research Project of the Miura Peninsula Fault Zone and Sagami Trough<\/p>\n\n\n\n
AUTHOR: *Tatsuya ISHIYAMA\uff65Hiroe MIYAKE\uff65Eiji KURASHIMO\uff65Takashi FURUMARA\uff65Shinichi SAKAI and Masanobu SHISHIKURA (GSJ, AIST)<\/p>\n\n\n\n
SUMMARY: We overview results of multidisciplinary researches on Miura Peninsula fault zone and Sagami trough, including the MEXT project \u201cComprehensive Research Project for the Miura Peninsula Fault Zone\u201d.<\/p>\n\n\n\n
2. 13:45-14:00<\/p>\n\n\n\n
TITLE: Seismic Source Characterization in the Marmara Sea Using Distributed Acoustic Sensing<\/p>\n\n\n\n
AUTHOR: *Ji ZHANG\uff65Aitaro KATO, Ahmet Anil DINDAR(MARTEST Research and Training Center, Gebze Technical University) and Wei WANG(Key Laboratory of Earth and Planetary Physics, Institute of Geology and Geophysics, Chinese Academy of Sciences\/College of Earth and Planetary Sciences, University of Chinese Academy of Sciences)<\/p>\n\n\n\n
SUMMARY: We used distributed acoustic sensing (DAS) on a pre-existing fiber-optic cable to locate small seismic events and image the rupture process of a large earthquake in the Marmara Sea.<\/p>\n\n\n\n
3. 14:00-14:15<\/p>\n\n\n\n
TITLE: Revealing Widespread Non-Double-Couple Earthquakes in Tottori, Japan<\/p>\n\n\n\n
AUTHOR: *Ji ZHANG\uff65Aitaro KATO, Wei WANG(Key Laboratory of Earth and Planetary Physics, Institute of Geology and Geophysics, Chinese Academy of Sciences\/College of Earth and Planetary Sciences, University of Chinese Academy of Sciences), Shin\u2019ichi SAKAI, Satoshi MATSUMOTO(Institute of Seismology and Volcanology, Faculty of Sciences, Kyushu University) and Yoshihiro ITO(Disaster Prevention Research Institute, Kyoto University)<\/p>\n\n\n\n
SUMMARY: We conduct full moment tensor (MT) inversions to systematically identify and quantify non\u2013double-couple (NDC) events, which are consistent with fluid-assisted rupture processes and complex fracture structures.<\/p>\n\n\n\n
4. 14:15-14:30<\/p>\n\n\n\n
TITLE: Structural barriers control the spatial extent of slow earthquake slip<\/p>\n\n\n\n

Tokyo), Yusuke YAMASHITA(Miyazaki Municipal Univ.), Hiroko SUGIOKA(Kobe Univ.), Atikul Haque FARAZI (Barishal Univ.), Shukei OHYANAGI\uff65Yoshihiro ITO(Kyoto Univ), Ryuta ARAI\uff65 Eiichiro ARAKI\uff65Gou FUJIE\uff65Yasuyuki NAKAMURA\uff65Takashi TONEGAWA(JAMSTEC), Ryosuke AZUMA\uff65Ryota HINO(Tohoku Univ.) Kimihiro MOCHIZUKI\uff65Shunsuke TAKEMURA\uff65Tomoaki YAMADA and Masanao SHINOHARA<\/p>\n\n\n\n
5. 14:30-14:45<\/p>\n\n\n\n
TITLE: Depth distribution and b-value characteristics of volcanic earthquakes occurring before, just before, and after the 2008 Shinmoe-dake eruption<\/p>\n\n\n\n
