Detailed Description

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.
