Description: From Neal and others, 1996: "On April 5-6, 1993, seven earthquakes were located in the general vicinity of Mount Churchill, a late Holocene volcano in the eastern Wrangell Mountains and the source of the White River Ash (Richter and others, 1995). Analysis of the seismicity by AVO seismologists indicated a tectonic rather than volcanic source. The tectonic nature of the earthquake swarm was mentioned in the weekly update of April 9, 1993."
