LiDar, faults, and earthquake studies

I recently came across another regional earthquake-related blog that was new to me. Groundswell was created to increase awareness and spread information about seismicity, earthquake research and mitigation efforts in the southwestern US.

Groundswell had a post about LiDar and fault studies. LiDar - light detection and ranging - is a very precise way of obtaining digital elevation models from aircraft using laser beams reflected from the Earth's surface.

Groundswell linked to a video from the website OpenTopgraphy, "A Portal to High-Resolution Topography Data and Tools," an NSF supported facility based at the University of California, San Diego.

Here is that video:
