Constraints on temporal clustering of earthquakes, Eastern California Shear Zone

We are currently focusing on the strike-slip faults of the sastern California shear zone (ECSZ). It is an ideal natural l aboratory because of its recent seismicity, accessibility, excellent geologic exposure and availability of high quality seismic and geodetic data. Our goals are to characterize the temporal and spatial record of earthquake occurrence along major faults of the ECSZ. Our research is aimed at collecting paleoseismic data that will (1) enable us to better understand the apparent earthquake clustering observed in the ECSZ from our earlier research, (2) evaluate the repeatability of earthquake ruptures and segmentation within the ECFZ, and (3) assess the discrepancy between geodetic and geologic deformation rates using slip rates inferred from recurrence intervals determined from paleoseismic studies.
