The goal of this study is to collect geologic data that can be used to evaluate the fault slip history and earthquake potential of the northern San Jacinto Fault Zone. This will allow us to estimate earthquake hazards and understand the kinematic relations between the San Jacinto and San Andreas fault zones in the region.

Using a combination of field mapping, analysis of B4 LiDAR data, geochronology, and trenching we are working to determine the structure and kinematics of the fault zone, estimate the Quaternary slip-rate, and document the paleoseismology for the northern San Jacinto.

The map below shows the study area and the location of the Mystic Lake paleoseismic site where we have documented 11 events in the upper 3m (1800 yBP). See the recent BSSA papers on the publications page.
