LiDAR data can offer a high resolution, near field dataset for analyzing fault motion. Single scan and multiple scan case studies will be presented at two points along the San Andreas- the Elizabeth Tunnel, in the south, and Napa Valley, in the north. The Elizabeth Tunnel is part of the Los Angeles aqueduct and was built between 1907 and 1911 and only one LiDAR data set is available for the tunnel. However, the tunnel location, roughly 87 m under the surface, offers a unique observation site for movement along the fault. Conversely, multiple LiDAR data sets are available both before and after the Napa earthquake on August 24, 2014. Various analysis methods that can be used to measure fault displacement in multiple scan LiDAR data sets will be presented and compared.
