ANCHORAGE, Alaska – The Latest on the eruption of Alaska's Pavlof Volcano (all times local):
11:30 a.m.
An ash cloud from an Alaska volcano rose to 37,000 feet and stretched Monday more than 400 miles into interior Alaska.
Pavlof Volcano, one of Alaska's most active volcanoes, erupted Sunday afternoon.
The Alaska Volcano Observatory says activity continued Monday.
Pavlof Volcano is 625 miles southwest of Anchorage on the Alaska Peninsula, the finger of land that sticks out from mainland Alaska toward the Aleutian Islands.
Lighting was detected over the volcano, and pressure-sensor data indicated sustained ash emissions.
Satellite date indicates the size of the ash cloud and its northeast flow.
Geologist Chris Waythomas of the U.S. Geological Survey says Pavlof can erupt for hours to days or erupt intermittently for longer periods of time.
The Federal Aviation Administration has issued a notice to pilots on the ash threat.

The U.S. Geological Survey reports that a volcano on the Alaska Peninsula erupted Sunday afternoon and sent ash 20,000 feet into the air.
The agency says the Pavlof Volcano, which is 625 miles southwest of Anchorage, erupted at 4:18 p.m. local time. The agency says the eruption also led to tremors on the ground.
The USGS has raised the volcano alert level to "Warning."
The agency says the volcano, which is about 4.4 miles in diameter, has had 40 known eruptions and "is one of the most consistently active volcanoes in the Aleutian arc."
The USGS says that during a previous eruption in 2013, ash plumes rose 27,000 feet. Other eruptions have generated ash plumes as high as 49,000 feet.
The community closest to the volcano is Cold Bay, which is about 37 miles southwest of it.
