No major explosions at Bogoslof in over a month, researchers say

By  | 

UNALASKA, Alaska (KTUU) - After a months-long eruption that began in mid-December, Bogoslof Volcano on the Aleutian chain has been quiet for the last two weeks, according to reports from the Alaska Volcano Observatory.

According to an AVO report issued Friday, the last major explosive event recorded at Bogoslof was on March 8 and a smaller one on March 13. Since then, data from satellites and other sensors has shown little activity on the island.

While the volcano has been quiet, researchers say that could still change.

“Though the volcano is currently quiet, renewed activity could occur at any time and could include additional explosive events and/or effusion of a lava dome.

AVO says it’s continuing to monitor Bogoslof with satellite imagery, pressure sensors from Umnak Island and seismic data from Unalaska.

Several large explosions at Bogoslof earlier this year created ash clouds as high as 30,000 feet, prompting numerous aviation warnings. Researchers say the activity even changed the shape of the island.
