[S-SS12] Crustal Structure

Thu. May 30, 2019 3:30 PM - 5:00 PM A05 (TOKYO BAY MAKUHARI HALL)

convener:Kazuo Nakahigashi(Tokyo University of Marine Science and Technology), Chairperson:Tsuruga Kayoko(Tokyo University of Marine Science and Technology), 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.
