Worldview-2 satellite image of Bogoslof volcano collected on March 11, 2017 at 22:15 UTC (1:15 PM AKST). Eruptive activity on March 8 produced large changes in the shape and size of the island. The most active vent for the explosive activity is located under the water in the center of the island, and it was greatly enlarged by the March 8 event. The western coastline has grown, and a new vent was produced on the north shore of the island. Image data provided under Digital Globe NextView License.


An ongoing earthquake swarm has been detected at Bogoslof over the past day. No significant volcanic activity has been detected in infrasound or mostly clear satellite data during the last 24 hours. The current swarm follows two previous swarms on March 10 and 11 that did not lead to significant eruptive activity. Occasional earthquakes were occurring at Bogoslof overnight March 11-12. The rate of earthquakes increased to one every 10 minutes at approximately 5:00 AKDT March 12 (13:00 UTC), signaling the beginning of the ongoing swarm. AVO is monitoring the current activity closely and will provide updates as warranted.
