A M4.7 earthquake hit near the Redoubt volcano and the Iliamna volcano on May 1, 2016 at 20:38:45 (UTC).
Both volcanic peaks are active stratovolcano in the volcanic Aleutian Range of the U.S. state of Alaska. Redoubt has erupted four times since it was first discovered: in 1902, 1966, 1989 and 2009 and nothing big at Iliamna yet.
According to USGS, a M4.7 earthquake hit 45km SSW of Redoubt Volcano, Alaska on May 1, 2016 at a depth of 130.6 km (81.2 mi).
The above map also shows that the earthquake actually struck near the Iliamna volcano as well.
Both stratovolcanoes are situated in the largely volcanic Aleutian Range in southwest Alaska. Mount Iliamna is covered by a glacier.
According to Wikipedia, fumaroles produce nearly constant and vigorous plumes of condensate and minor amounts of sulfurous gases. These plumes have resulted in numerous pilot reports and early historical accounts of “eruptions” at Iliamna Volcano. Is it waking up?
