[S-SS13] Crustal Structure

Mon. May 25, 2026 10:45 AM - 12:15 PM Exhibition Hall Special Setting (6) (Exhibition Hall 7&8, Makuhari Messe)

Chairperson:Nakatani Yukihiro(Graduate School of Science and Engineering, Kagoshima University), Miura Seiichi(Japan Agency for Marine-Earth Science and Technology)

This session aims to cover seismological and geophysical studies on the Earth's crust and uppermost mantle. Contribution to the seismological and geophysical structure of the crust and processes that develop in the crust which includes 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.This session is a Japanese/English session for presentation and discussion in Japanese because many similar sessions are English session. Moreover, this session is also for the presentation/discussion of Japanese name project without English name. We welcome the presentation from local to global scale with Japanese and English language.
