The energy of volcanic earthquakes sharply increased during 2-4 May, and then decreased on 5 May. The average number of volcanic earthquakes declined from 35-49 events per day in early-to-mid May, to 14 events per day in mid-to-late May. The number of events continued to decline through the beginning of June.
The number of local tectonic earthquakes also decreased significantly from an average of 67-71 events per day in early-to-mid May, to 2-17 events per day the latter half of May, to about 2 events per day in early June.
Based on the visual observations and decline in seismicity, CVGHM lowered the Alert Level to 2 (on a scale of 1-4).
