(CNN) — Alaska’s Pavlof Volcano, which erupted suddenly over the weekend, continued to rumble and fling ash into the sky on Monday, the Alaska Volcano Observatory said.

The ash plume is now 37,000 feet high and trails some 400 miles to the northeast over the Alaskan interior, the observatory said. Aviation alerts were up in the region.

Mariners, pilots and residents in nearby Cold Bay saw lava flowing from the top of the volcano throughout the night, the observatory said.

The volcano began erupting suddenly on Sunday, the observatory said. It’s the first eruption for the volcano since 2014.

Pavlof, which is about 7 miles in diameter and located 592 miles southeast of Anchorage, is described by the center as “one of the most consistently active volcanoes in the Aleutian Arc.” In the past, it has sent ash plumes as high as 49,000 feet, according to the observatory.
