This electronic supplement contains annotated topographic contour maps and hillshades generated from raw and filtered B4 LiDAR data, corresponding field photographs, and data tables comparing LiDAR-based and field-based slip measurements for individual geomorphic features along the Clark fault.
The B4 LiDAR Project collected LiDAR point cloud data of the southern San Andreas and San Jacinto Faults in southern California. Data acquisition and processing were performed by the National Center for Airborne Laser Mapping (NCALM) in partnership with the USGS and Ohio State University through funding from the EAR Geophysics program at the National Science Foundation (NSF). Optech International contributed the ALTM3100 laser scanner system. UNAVCO and SCIGN assisted in GPS ground control and continuous high rate GPS data acquisition. A group of volunteers from USGS, UCSD, UCLA, Caltech and private industry, as well as gracious landowners along the fault zones, also made the project possible.
For more information about the B4 Project, please visit "http://earthsciences.osu.edu/b4/Site/Welcome.html". The B4 LiDAR dataset is available in many formats via "http://www.opentopography.org" for neotectonic and paleoseismic research.
Clark Fault Offsets.kmz. This downloadable Google Earth index file (KMZ) contains the locations of offset features along the Clark strand of the San Jacinto Fault.
Note: All hillshades and topographic maps were created with raw or filtered B4 LiDAR data.
