1. 13:30-13:45
TITLE: Toward high-resolution study of megathrust: a new approach from
passive source study
AUTHOR: *Takeshi AKUHARA・Masanao SHINOHARA・Kimihiro MOCHIZUKI,
Yusuke YAMASHITA・Shukei OHYANAGI and Farazi Atikul HAQUE (Kyoto Univ.)
SUMMARY: We have deployed a dense OBS array and developed an analysis method
for high-resolution study of the megathrust.

2. 13:45-14:00
TITLE: New progress in building Pacific Array: an international collaboration
to image mantle dynamic processes across the Pacific basin
AUTHOR: *Hitoshi KAWAKATSU, James B. GAHERTY (Columbia University),
Hisashi UTADA, Sang-Mook LEE・Younghee KIM (Seoul National University)
and Zachary EILON (UC Santa Barbara)
SUMMARY: This is the same as the presentation given at AGU2019 in San Francisco,
but will be given in Japanese.

3. 14:00-14:15
TITLE: Experimental study of effects of partial melting on polycrystal
anelasticity: toward quantitative interpretations of seismic low velocity
and high attenuation near subduction zones
AUTHOR: *Hatsuki YAMAUCHI and Yasuko TAKEI

4. 14:15-14:30
TITLE: Compliant Volcanic Arc and Backarc Crust in Southern Kurile Suggested by
Interseismic Geodetic Deformation
AUTHOR: *Yuji ITOH, Kelin WANG (Pacific Geoscience Centre,Geological Survey of Canada),
Takuya NISHIMURA (Disaster Prevention Research Institute, Kyoto University)
and Jiangheng HE (Pacific Geoscience Centre, Geological Survey of Canada)
SUMMARY: Margin-normal variation in compliance of an upper plate in the southern
Kurile subduction zone (i.e., eastern Hokkaido) is constrained by
interseismic GNSS (Itoh et al., 2019, GRL).
