Makushin volcano (Fox Islands, USA) - Smithsonian / USGS Weekly Volcanic Activity Report for 30 May-5 June 2001 (New Activity / Unrest)

Since July 2000 AVO has detected a slight increase in the number of small earthquakes beneath Makushin. The earthquakes generally ranged in depth between 0 and 8 km and were too small to be felt by humans (M0-1.5). The seismic activity was not considered to be an immediate precursor to eruptive activity.
Similar fluctuations in earthquake activity have been observed at a number of Aleutian volcanoes that did not result in an eruption. The Concern Color Code remained at Green.
