Central San Andreas Fault

Our research documenting the distribution of creep at Dry Lake Valley on the creeping section of the San Andreas Fault has been published. This is an exciting piece of work to get out, as it represents several years of work documenting surface fracturing and quantitatively estimating creep magnitude recorded in the fractures, and using SfM photogrammetry to make a very high quality point cloud of the land surface that Dr. Chelsea Scott (Arizona State University) differenced against LiDAR collected 10 years previously to quantify the distribution of deformation along and across the fault.
