The Alaska Volcano Observatory has lowered the aviation alert level for an erupting volcano on the Alaska Peninsula.
The observatory says the threat level for the Pavlof (PAV-lawf) Volcano 625 miles southwest of Anchorage is now at the orange watch level rather than the red warning level.
The observatory in an announcement Tuesday night says Pavlof continues to erupt but seismic tremors have diminished since an ash cloud shot into the air Monday afternoon. The tremors have remained steady at the lower level for 12 hours.
The observatory says a plume from the volcano is now in two parts and the higher plume is mostly steam and gas with little ash that could threaten aircraft.
The observatory warns that with an ongoing eruption, conditions can change rapidly.
