Tectonic geomorphology and earthquake geology of the 1857 reach of the San Andreas Fault: a new look from Airborne Laser Swath Mapping

The above image is an aerial photograph (that is rectified to 4 cm pixels) taken from our balloon system. Brian Campbell and Ramon Arrowsmith took the photo over the San Andreas Fault in the Carrizo Plain in June, 2006. It was rectified to and draped over a 25 cm digital elevation model produced from B4 project airborne lidar survey data gridded using the GEON LiDAR Workflow (GLW) (http://www.geongrid.org/science/lidar.html). The GLW is a tool for the distribution and processing of LiDAR point cloud data (see: http://lidar.asu.edu/ for more information on this project). Note the stream channel offset 15 meters along the San Andreas Fault in the middle of the photo.

This research is supported by the Southern California Earthquake Center and the National Science Foundation through the the GEON project.
