USA, California, Walnut Creek: 1970-2019

Summary

The Walnut cluster is named after the town of Walnut Creek in northern California, U.S.A. It includes the South Napa 6.0 Mw event on August 24, 2014 and several other events with magnitude 5+. All events are recorded at least to far-regional distances and most have teleseismic observations. All events have depth control from near-source or local-distance readings. A kernel of events with especially good data were relocated with free depth to refine the crustal model. Very near-source readings, less than about 15 km epicentral distance, exhibit more scatter than usual in this cluster, likely due to the extreme variability of crustal structure and topography in the source region.
