Alaska’s Pavlov Volcano, which erupted Sunday afternoon, originally sent ash 20,000 feet into the air, according to the USGS.
However, the volcano continues rumbling and flinging ash into the sky today (Monday), the Alaska Volcano Observatory said.
The ash plume is now 37,000 feet high, the observatory said.
The USGS hasraised the aviation warning to “Red.”
Mariners, pilots and residents in nearby Cold Bay saw lava flowing from the top of the volcano throughout the night, the observatory said.
The Pavlof Volcano, on the Aleutian Islands, is located about 600 miles southwest of Anchorage.
According to the USGS, the volcano has had 40 known eruptions and “is one of the most consistently active volcanoes in the Aleutian arc.”
