Measuring Earthquake-Generated Surface Offsets from Lidar

David Haddad, a PhD student at Arizona State University and one of the most frequent users of OpenTopography, recently sent along a PDF document that he has prepared on his recent work using lidar data accessed via OT to constrain meter-scale offsets along strike-slip faults in southern California. David's document provides an overview of the workflow involved in calculating surface slip offsets using LiDAR-derived DEMs and is a nice tutorial on how to access data from OT.

Death Valley - Fish Lake Valley Lidar Update

There has been some discussion recently regarding the status of the Death Valley-Fish Lake Valley lidar dataset collected on behalf of Principle Investigator Dr. James Dolan (USC) under the National Science Foundation GeoEarthScope project. These lidar data cover the Death Valley-Fish Lake Valley (DV-FLV) fault system on the California-Nevada border and are the last of the EarthScope funded lidar data to be made available through OpenTopography.
