ALASKA VOLCANO OBSERVATORY INFORMATION STATEMENT
U.S. Geological Survey
Monday, May 8, 2017, 4:31 PM AKDT (Tuesday, May 9, 2017, 00:31 UTC)
51°47'21" N 178°47'46" W,
Summit Elevation 5161 ft (1573 m)
Current Volcano Alert Level: NORMAL
Current Aviation Color Code: GREEN
The magnitude 6.0 earthquake that occurred this morning at 09:00 AKDT (17:00 UTC) near Gareloi volcano was part of an ongoing swarm of shallow earthquakes that has been active between Gareloi and Tanaga Islands since April 30. At this time, the event and ongoing swarm appear to be tectonic in nature, and there is no indication that the earthquakes are related to volcanic activity. Convergence between the down-going and overriding plates produces deformation in the upper plate which results in shallow crustal earthquakes. Aftershocks are also typical of such events. AVO will continue to monitor the volcanoes closely for indications of volcanic activity.

OTHER ALASKA VOLCANOES
Information on all Alaska volcanoes is available at : http://www.avo.alaska.edu.
AVO scientists conduct daily checks of earthquake activity at all seismically-monitored volcanoes, examine web camera and satellite images for evidence of airborne ash and elevated surface temperatures, and consult other monitoring data as needed.
