Turley said their first thought was that the bubbles were from something decomposing in the ponds or from tidal action, but theyd never seen them before and thought the bubbles remarkable enough to report them to Cameron, who is Tlingit and from Sitka. A poorly documented eruption occurred in 1945, also producing a lava dome that was partially destroyed in the 1974 eruption. The eruptions do not pose a threat to any nearby community due to the location of the Aleutian island chain, an 800-mile stretch of islands that ring the Bering Sea. Three remote Alaska volcanos are each in a state of eruption, one producing lava and the other two blowing steam and ash. Hearing a volcano, or any sound, so far away from its origin is a pretty rare phenomenon, said David Fee. The 2001 eruption also produced a lava flow and hot avalanche that reached the sea. Other volcanoes have had similar amounts of deformation without erupting, Coombs said, noting that the ground around Laguna del Maule in Chile has been bulging outward even more quickly than Edgecumbe, and for a longer period, without an eruption. It definitely has moved up, said Cheryl Cameron, a state geologist who works at the volcano observatory. Active lava. We expect additional shallow seismicity and other signs of unrest, such as gas emissions, elevated surface temperatures, and surface deformation to precede any future eruption, if one were to occur. Turley said their first thought was that the bubbles were from something decomposing in the ponds or from tidal action, but theyd never seen them before and thought the bubbles remarkable enough to report them to Cameron, who is Tlingit and from Sitka.
