Anomalous Seismicity in the San Diego Coastal Region

Abstract

This short note documents recent seismic activity in the coastal region adjacent to San Diego. Seismic activity in the region has increased dramatically since 1983 when compared with previous historic activity. Similar increases in seismicity, that occurred prior to significant earthquakes in California, are also documented. It is speculated that the tectonic style in the continental borderland off of San Diego is very similar to that in the Basin and Range province.
