The Aleutian Islands' still-rumbling Bogoslof volcano is once again under higher alert levels after the latest of several eruptions there in the past week.

Alaska Volcano Observatory posted a Tuesday afternoon update slightly lowering the alert level to "watch" for Bogoslof, about 60 miles west of Unalaska, and its aviation color code to orange. The volcano had been at "warning" and red," the observatory's highest alert levels, since an eruption Monday afternoon.

Seismic data and satellite images showed an "ash-producing eruption" and cloud at the volcano just after 2 p.m. Monday, following at least three last week that reshaped much of low-lying Bogoslof Island.
