Airborne lidar survey of surface ruptures and ground failure features associated with the 4 and 5 July 2019 Ridgecrest Earthquake sequence. This dataset covers the non-tectonic Trona Pinnacles & Argus surface disturbance area. This region is not along the primary tectonic surface rupture , but was collected as part of a larger data collect which covers the areas impacted by the Ridgecrest earthquake.
