Scientists have upgraded the alert level at one of Alaska's most active volcanoes after increased volcanic unrest.

Starting last week, satellites detected an increase of gas emissions and elevated surface temperatures at Cleveland Volcano, which is located on an uninhabited island in the central Aleutians, west of Umnak Island.

The data indicates a potential for increased eruptions, according to Dave Schneider, a geophysicist with the Alaska Volcano Observatory, so the AVO has raised the aviation color code to "yellow" and the alert level to "advisory."

A magnitude-7.8 Aleutian earthquake late Tuesday night prompted tsunami warnings in communities across coastal Alaska, from Homer to Unalaska.  

Sand Point is a fishing community of about a thousand people, located about 550 miles southwest of Anchorage in the eastern portion of the Aleutian Chain. Earthquake damage closed both its city docks, which it uses to land the M/V Tustumena ferry and freight boats, and damaged the road to the harbor.

Through last week, U.S. commercial airlines — distinct from the smaller bush planes that carry Alaskans to rural villages — had gone a full decade with just one paying passenger dying in an accident.

That changed last Thursday when a PenAir flight with 42 people crashed off the end of the runway in Unalaska, killing David Oltman, 38, of Wenatchee, Washington.

Now, the family that founded PenAir is raising questions about the safety standards of the new owners that bought the company out of bankruptcy last year.

Mother Nature didn't deliver on Tuesday night's forecast of four to eight inches of snow.

The National Weather Service canceled Unalaska's winter weather advsory after midnight, although the island did receive strong winds and some in-town snow accumulation.

Forecasters say snow is likely again on Wednesday. But as of noon, they had reduced their prediction of possible accumulation from three inches to less than a half inch.
