Finding Faults

Looking for Faults in NW Washington

This article discusses looking for faults in the Olympic Peninsula of Washington State. These are not the faults of the offshore Cascadia fault zone but they are associated with structural damage and some deaths. Because of the terrain and the abundant vegetation, faults are difficult to find but LIDAR is proving very useful.
