Exciting news! We're transitioning to the Statewide California Earthquake Center. Our new website is under construction, but we'll continue using this website for SCEC business in the meantime. We're also archiving the Southern Center site to preserve its rich history. A new and improved platform is coming soon!

Ridgecrest earthquake sequence NCALM airborne lidar datasets released via OpenTopography

Date: 03/27/2020

On Behalf of Ken Hudnut, U.S. Geological Survey:
--------------------------------------------------------------------

We are pleased to announce the release of two new 2019 lidar datasets, collected by the National Center for Airborne Laser Mapping (NCALM) and funded by the U.S. Geological Survey (USGS) and the U.S. National Science Foundation (NSF), covering 293 km2 of the region impacted by the 2019 Ridgecrest earthquake sequence in southern California. The datasets cover a portion of the main surface fault ruptures of both of the M 6.4 and M 7.1 Ridgecrest earthquake sequence, as well as the areas of non-tectonic ground deformation near Trona and Argus, CA including the fragile geological features called the Trona Pinnacles. An additional portion of the surface fault rupture coverage area is expected to be made available pending its approval for public release.

The data are now available via links contained in the data announcement from OpenTopography:

Please let me know if you have any questions or would like a preprint of our team's SRL paper. *

Many thanks to all co-authors and everyone else involved in making this possible.

Stay safe & healthy, and enjoy the data!

Sincerely,

Ken
