    Airborne lidar survey of surface ruptures and ground failure features associated with the 4 and 5 July 2019 Ridgecrest Earthquake sequence. As of 06/12/2020: This new release adds data over Naval Air Weapons Station China Lake, and now covers the main surface fault ruptures of both the M 6.4 and M 7.1 Ridgecrest earthquake sequence. In addition, all data have now been classified by NCALM
