Earthquake Geology

Director Kerry Sieh’s principal research interest is earthquake geology, which uses geological layers and landforms to understand the geometries of active faults, the earthquakes they generate, and the crustal structure their movements produce. His early work on the San Andreas fault led to the discovery of how often and how regularly it produces large earthquakes in southern California.

More recently, his group has begun a study of the earthquake geology of Myanmar and New Guinea. Current research is especially focused on the subduction megathrust that produced the devastating giant Aceh-Andaman earthquake and Indian Ocean tsunami of 2004.

The basaltic Bolaven volcanic field covers 11,000 km2 of southern Laos and has erupted often in the past half-a-million years. Nonetheless, the exposure of populations and infrastructure to its volcanic hazards is unknown.

This project is a multi-lateral collaboration between several EOS researchers and colleagues at other research institutions to study the tectonics and earthquakes of Southeast Asia.
