The Alaska Volcano Observatory (AVO) has lowered the alert levels for two Aleutian volcanoes.

Bogoslof is back at the intermediate "watch" level, following a powerful eruption Tuesday night.

The volcano hasn’t produced ash since that three-hour blast and its seismicity has died off, but scientists say Bogoslof could blow again with little warning.

Meanwhile, Cleveland Volcano -- 45 miles west of Nikolski -- has been quiet since a small eruption last month.

Satellite data shows that lava has cooled within the crater, so the AVO has downgraded Cleveland to a low-level "advisory."
