Alert as Alaska volcanoes spew lava

Lava flowed Tuesday from two Alaskan volcanoes, with authorities placing both on the second-highest alert levels because "sudden explosions ... are possible with little or no warning."

The volcanoes are Pavlof and Cleveland, both in the Aleutian Island range southwest of mainland Alaska. The Alaska Volcano Observatory has issued a watch due to heightened activity, plus an orange code regarding how they might affect planes in the area.

At Pavlof, the higher of the two summits at 8,261 feet, the observatory reported "eruptive activity" that followed "an increase in seismic activity."

Lava has been spotted about 0.3 of a mile (half a kilometer) down the volcano's north flank.

Unlike Cleveland, Pavlof is not on an island but rather is connected to the Alaskan mainland.
