[S-SS26] Crustal Structure

Sun. May 22, 2016 9:00 AM - 10:15 AM 201A (2F)

Convener:*Koichiro Obana(Research and Development Center for Earthquake and Tsunami, Japan Agency for Marine-Earth Science and Technology), Chair:Yoshio Murai(Institute of Seismology and Volcanology, Faculty of Science, Hokkaido University), Yojiro Yamamoto(Japan Agency for Marine-Earth Science and Technology)

The aim of this session is to cover seismological and geophysical studies on the Earth's crust. Contribution on seismological and geophysical structure of the crust, processes that develop in the crust which include earthquakes, volcanoes and geological descriptions of the crust are welcomed. We also welcome theoretical and methodological studies that will serve as basics in such explorations.
