The eruption of Alaska's Pavlof volcano continued Monday, spouting fountains of lava and a plume of volcanic ash more than 11 kilometres into the atmosphere, the Alaskan Volcanic Observatory reported.
The ash cloud spread more than 650 kilometres to the north-east, over Alaska's interior, and triggered an aviation warning.
No casualties or property damage were reported from the eruption of the snow-covered volcano on the remote Alaska Peninsula, 953 kilometers south-west of Anchorage.
The nearest community, Cold Bay, is 60 kilometers south-west of the volcano.
With more than 40 past eruptions, Pavlof is one of the most active volcanos of the Aleutian arc, the Alaskan Volcanic Observatory said. Last active in 2014, the volcano sprang back to life Sunday afternoon.
Alaska has 52 active volcanoes.
