OT Collection Name: August 24, 2014 South Napa Earthquake
Short Name: NAPA_2014
Collection Platform: Airborne Lidar
The August 24, 2014, South Napa earthquake (M6.0) produced significant damage resulting from shaking, fault rupture, fault afterslip, and ground deformation. Lidar data were collected to aid specialized work on the South Napa earthquake including: (1) fault afterslip, especially in the Browns Valley residential neighborhood; (2) shaking and correlation to damage such as red- and yellow-tagged structures, especially in the downtown Napa area; (3) seismic hazards of the West Napa Fault System, especially in residential areas; and (4) geospatial analysis and imagery support (such as post-processing of lidar and other imagery that has already been acquired).
Airborne lidar data and imagery were collected on September 9, 2014 as part of multi-agency/institutional response to the August 24, 2014 South Napa Earthquake. Details of the scientific response to this earthquake including the lidar acquisition can be found in Hudnut et al., 2014: USGS Special Open-File Report 2014-1249. Data were collected and initially processed by Towill and are available both as raw files and products as initially delivered by the vendor, as well as the USGS re-processed version of re-classified point clouds and 0.25 meter DEM's from the USGS HDDS Explorer. Point clouds available from USGS and OpenTopography were reclassified (metadata) by the US Geological Survey; this re-processing was funded by FEMA. Orthoimagery were collected by Towill on September 9, 2014, and by Google on August 24, 2014.
