[S-SS14] Active faults and paleoseismology

Mon. May 26, 2025 9:00 AM - 10:30 AM Exhibition Hall Special Setting (6) (Exhibition Hall 7&8, Makuhari Messe)

convener:Mamoru Koarai(Earth Science course, College of Science, Ibaraki University), Suguru Yabe(National Institute of Advanced Industrial Science and Technology), Kiyokazu Oohashi(National Institute of Advanced Industrial Science and Technology ), Kyoko Kagohara(Yamaguchi University), Chairperson:Mamoru Koarai(Earth Science course, College of Science, Ibaraki University), Kyoko Kagohara(Yamaguchi University)

Geologic and historic information on seismic cycles and on the magnitude and source faults of past earthquakes is essential information to understand future large earthquakes. The study of past faulting and seismicity is an important issue for an interdisciplinary community of seismologists, geologists, geomorphologists, archaeologists, and historians.
