Alaska volcano eruption eases after emitting massive ash cloud

An eruption of the Shishaldin Volcano in Alaska has “gradually declined,” according to the Alaska Volcano Observatory.

However, low-level ash emissions below 10,000 feet above sea level continue and a significant ash plume was produced Tuesday morning, reaching a height of around 30,000 feet. 

The plume has since detached, but remained visible between 60-280 miles away from the volcano. 

The National Weather Service issued a SIGMET for the cloud. SIGMETs are brief descriptions of the development and occurrence or expected occurrence in time and space of specified en-route weather phenomena which may affect the safety of all aircraft operations, according to the agency. 

Unimak Island has about 65 residents northeast of the volcano in the community of False Pass. 

Shishaldin Volcano began erupting on July 11, with strongly elevated surface temperatures reported at the summit.
