Abstract (Summary)

Detailed tectonic geomorphic mapping was conducted along the Claremont fault, the northern segment of the San Jacinto fault zone in southern California, using both LiDAR data and field observations. The field area was a 13 km section of the Claremont fault southeast of Lorna Linda, California. 133 fault-related geomorphic features were identified, and of those 57 were determined to be tectonically offset or deflected streams. These data, along with paleosiesmic data from another site, suggest that there is evidence for eight earthquakes preserved in these tectonically deflected streams. Of these potential eight earthquakes, this study was primarily concerned with the last two ground rupturing earthquakes to occur on the Claremont fault because of the quality and quantity of the data collected for these two events. The data show an average displacement for the most recent earthquake of 4.0 m and an average displacement for the penultimate earthquake being 2.5 m.
