Three volcanoes located in remote parts of Alaska are all currently in different states of eruption.
The volcanoes Semispopchnoi, Great Sitkin, and Pavlov are located in the Aleutian Islands. The Great Sitkin volcano has been producing lava. The Semisopochnoi and Pavlov volcanoes have been producing ash clouds.
Located nearly 600 miles southwest of Anchorage, Pavlov is a stratovolcano, covered in snow and ice. According to the Aleutian Island arc of active and dormant volcanoes, Pavlov is one of the state’s most active.
Approximately 1,500 miles southwest of Anchorage, sits the Great Sitkin stratovolcano adorned with a caldera and dome. There have been reports of witnesses seeing a lava fountain at the volcano.
“The fact that they just happen to walk outside and see it was really great,” Chris Waythomas, a geologist with the Alaska Volcano Observatory, stated. “This lava fountain is kind of unusual for Great Sitkin, but it’s been fairly passive at this point.”
Semisopochnoi Volcano is found on an uninhabited island on the western end of the Aleutian Islands. Semisopochnoi produced an impressive ash cloud that reached about 10,000 feet high, Waythomas said. The volcano has been erupting intermittently before.
The three volcano eruptions happened about a week after an 8.2 magnitude earthquake in Alaska. It was the strongest earthquake to hit Alaska in decades.
