Summary

LiDAR is an exceptional tool for preserving and characterizing the geometric details of a fault scarp. Filtering allows for removal of vegetation and the imaging of a bald earth. Fault breaks in a trench wall, unseen by natural color imagery, may be observable by manipulating the spectral content and intensity of the LiDAR scan. Deploying LiDAR in the field is easy and routine, and the apparatus is highly portable.
