I employ various tools to study active faults: mapping fault excavations, analysis of lidar data, GIS analyses, marsh stratigraphy, and macro- and microfossil analyses. Several of the faults I am working on are unique in that they have very short, but very tall scarps - short rupture length, big displacements. For example, one scarp is about three kilometers long and has 8 meters of throw on it, likely in one event. This type of atypical surface rupture is common here in the Pacific Northwest and on some faults in Japan.
I’ll add more project specific information at a later date.
