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.
Sieh received his undergraduate degree in geology from the University of California, Riverside in 1972 and his Ph.D. degree in geology from Stanford University in 1977. He was a professor of geology at the California Institute of Technology from 1986 to 2009. Sieh is a member of the United States National Academy of Sciences (since 1999).
