[S-SS10] Active faults and paleoseismology

Fri. May 29, 2026 1:45 PM - 3:15 PM Exhibition Hall Special Setting (6) (Exhibition Hall 7&8, Makuhari Messe)

Chairperson:Koarai Mamoru(Earth Science course, College of Science, Ibaraki University), Soeda Yoshio(West Japan Engineering Consultants,Inc.)

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.
