Title: Using bare-earth LiDAR imagery to reveal the Tahoe - Sierra frontal fault zone Lake Tahoe, California.


This video provides a visual example of how airborne LiDAR (Light D etection And Ranging) imagery penetrates dense forest cover to reveal an active fault line not detectable with conventional aerial photography. The video shows an aerial perspective of the range front Mt. Tallac fault, which is one of five active faults that traverse the base of the steep mountains west of Lake Tahoe, California. The USGS has recently published a report in the Bulletin of the Geological Society of America that details the seismic hazards of the Tahoe -Sierra frontal fault zone mapped with the new technology.
