From Dixon and others (2015): "Starting on March 29, Korovin Volcano experienced a 2-week-long swarm of small earthquakes located 2-4 km (1.2-2.4 mi) northwest of the summit of Korovin. Earthquake activity peaked on April 10, with a rate of 10 earthquakes per hour, and the swarm ended by April 12 (fig. 45 in original text). Throughout 2013, AVO noted isolated tremor at Korovin. In comparison, this tremor released about one-third of the energy level of tremor associated with a 2006 period of unrest at Korovin. The Aviation Color Code and Volcano Alert Level remained UNASSIGNED/UNASSIGNED throughout the year."
