Bogoslof Island is currently under close monitoring by the Alaska Volcano Observatory after a series of explosive eruptions in the uninhabited island. Experts are keeping an eye on the volcano in the eastern Aleutian islands through seismic monitors and satellite imagery.
Bogoslof Island Eruptions
The first eruption of the volcano in Bogoslof Island was noticed through satellite imagery and the pilots who were flying near the area on Dec. 21. The 10-kilometer ash plume appeared during the initial eruption but the volcanic activity did not last for a long time. The second big explosion that produced a 10.6-kilometer ash plume happened the day after, Dec. 22.
Given the isolated location of the island in the Bering Sea, the volcanic activity is only monitored through satellite imagery. A Red warning was issued after the eruption of the volcano but this was later lowered to an Orange warning after the diminished activity. Scientists do not know whether the eruption is isolated cases or if this is just the beginning in a series of eruptions.
Changes In The Aleutian Islands
Right now, volcanologists are interested in the changes brought about by the eruption of the volcano. The last recorded eruption was back in 1992 as reported by Wired. However, it was the eruptions in 1796 and 1883 that led to the formation of a new dome.
Based on the observations of the AVO scientists Michelle Coombs, the eruption of the Bogoslof volcano already produced new land although it also destroyed part of the island. As reported by KUCB, the scientists also observed that there is a new vent which is located "offshore of the little island." Due to the lack of local seismic monitoring, it would be difficult to predict the volcano's behavior.
The volcano may be in an isolated location but it can affect air traffic especially air crafts from Asia to North America. Bogoslof Island eruption is still under close monitoring to ensure everyone's safety.
