The alert level for Bogoslof Volcano has been downgraded to “normal” after more than three months of inactivity.

The Alaska Volcano Observatory made the announcement Wednesday, although scientists say remote monitoring makes it difficult to determine if the eruption is really over.

While Bogoslof exploded more than 40 times in the last year, the AVO says all signs now point to another period of quiet.

Meanwhile, scientists have upgraded the alert level for Shishaldin Volcano on Unimak Island.

They issued a low-level “advisory," citing weeks of increased seismic activity. That means Shishaldin is showing signs of unrest, but it doesn’t indicate an imminent eruption.
