Small earthquake epicenters near the Anza seismic gap define a 20‐km quiescent segment of fault bounded to the northwest and southeast by areas of relatively high seismicity. The ANZA seismic network was installed to monitor micro-earthquakes occuring near the San Jacinto fault zone near the town of Anza in Riverside County, California. Citation Li, Y., & Vernon, F. L. (2001). San Jacinto Fault Zone - Characteristics - Anza Seismic Gap. In a 1975 study, one of these (a 40 km (25 mi) stretch) was labeled the "Anza to Coyote Mountain slip gap", and was further refined in a 1984 paper by seismologists Christopher Sanders and Hiroo Kanamori to include only a smaller 20 km (12 mi) section near the town of Anza. 5876 sanders and l
