Seismic hazard assessment in Australia is based on the fundamental assumption that past earthquake activity is the key to what we might expect in the future. However, the instrumental record spans only 100-150 years and our historic record is not much more than 200 years. In recent times, high resolution digital elevation models (DEMs) have emerged as an important tool for finding and characterising earthquake related geomorphology, and particularly fault scarps. We present the results of a reconnaissance investigation of two DEM datasets covering a large portion of southwest and central Western Australia.
