|(11) Volcanic Activity Summary:||A short-lived eruption of Bogoslof volcano began June 13 at 01:47 UTC (17:47 AKDT June 12) and lasted about 9 minutes according to seismic and infrasound data. No ash cloud has been detected in satellite data yet but a single lightning stroke has been observed, thus volcanic ash emissions are likely occurring. Winds are to the southeast and no ashfall is expected on communities.
We are evaluating the magnitude of this eruptive episode and activity may resume at any time. The Aviation Color Code remains at ORANGE and the Volcano Alert Level remains at WATCH at present. AVO is evaluating all data sources and will update this report as more information becomes available.
