Two volcanoes in Alaska are still erupting, while one in Chile that erupted on Saturday has stopped, although another one threatens to erupt again.
In Alaska both Mount Cleveland and the Okmok volcano are erupting, but seismic activity at the Okmok decreased Sunday after more activity was recorded beginning on Friday. While in Chile, the Llaima volcano erupted on Saturday, then stopped, while the Chaitén volcano there could be ready to erupt again.
Okmok is located on Umnak Island.
The United States National Weather Service on Sunday issued a 24-hour ash-fall advisory, which expires at noon Monday, for Umnak Island and the southwest part of Unalaska Island.
In Chile, authorities issued a state of alert for villages near the 9,400-foot Llaima volcano. It is one of Chile's most active and since 1640 it has had 38 large eruptions. Chaitén had a major eruption on May 2, forcing the evacuation of nearby villagers who still haven't returned.
Llaima is located 400 miles south of Santiago. Chaitén is located 745 miles south of Santiago.
