Belle Philibosian
The focus of my research is to understand the earthquake cycle, using techniques drawn from the fields of active tectonics and paleoseismology. In various projects I have employed imagery- and LiDAR-based fault mapping, paleoseismic trenching, GPS and InSAR observations, and coral microatoll paleogeodesy. I pursue the dual goals of scientific understanding and hazard assessment of earthquakes.

San Andreas fault earthquake chronology and Lake Cahuilla history at Coachella, California
The southernmost ~100 km of the San Andreas fault has not ruptured historically. It is imperative to determine its rupture history to better predict its future behavior. This paleoseismic investigation in Coachella, California, establishes a chronology of at least five and up to seven major earthquakes during the past ~1100 yr. This chronology...

Photomosaics and Logs of Trenches on the San Andreas Fault near Coachella, California
Valley in southern California east of Dillon Road and south of Avenue 44. Three benched trenches, a total of more than 950 m, were excavated across the fault zone as part of an Alquist-Priolo fault investigation study. These trenches exposed a thick section of latest Holocene lacustrine, fluvial, and shoreline deposits. Only the central and...
