The high, isolated massif of Sheveluch volcano (also spelled Shiveluch) rises above the lowlands NNE of the Kliuchevskaya volcano group. Besides this brief swarm, overall seismicity was low. Additional ash-producing events could occur again with little warning. Fox News Flash top headlines are here. In October, they found something new gas bubbling through several ponds on the east side of the island. The movement doesn't mean an eruption will happen soon or even at all from Southeast Alaska's most prominent volcano, but it's significant enough that the observatory has . 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. Mount Edgecumbe is now considered a high risk volcano, one step below the states very high risk volcanoes: Augustine, Spurr, Redoubt, Akutan and Makushin. I think theyre doing due diligence and following through and they believe theres going to be lots of warning if we ever get to that point, and it may never happen..

Many posted on social media seeking answers. Great Sitkin Volcano is a basaltic andesite volcano that occupies most of the northern half of Great Sitkin Island, a member of the Andreanof Islands group in the central Aleutian Islands. They said theyre not concerned by the volcanos movement or the distant prospect of an eruption. Small eruptions producing minor ash deposits within the vicinity of the active north crater of Mount Young and ash clouds usually under 10,000 ft (3 km) above sea level have characterized the recent periods of activity. An undersea volcano erupted in spectacular fashion near the Pacific nation of Tonga on Saturday, sending large waves crashing across the shore and people rushing to higher ground. The Alaska Volcano Observatory is planning to install a series of seismic instruments on Mount Edgecumbe near Sitka after preliminary measurements showed magma moving deep below the Mount Fuji-shaped volcano. Crustal seismicity in this region can be attributed to the Kodiak Shelf Fault Zone and to the volcanic arc. Satellite images and web camera views were mostly cloudy during the last 24 hours. Hannah Dietterich, a research. Great Sitkin, a stratovolcano with a caldera and dome, is about 1,150 miles southwest of Anchorage.

A series of eruptions about 14,000 years ago spread volcanic ash across Southeast Alaska that may have helped melt the glaciers that covered the region at the time. Seismicity remains above background levels and is characterized by weak, low-frequency earthquakes. No significant activity was seen in mostly to partly cloudy web camera or satellite imagery. The current period of seismic unrest began on August 24, 2022. In Tonga it sent tsunami waves crashing across the shore and people rushing to higher ground. That eruption produced at least one ash cloud that likely exceeded an altitude of 25,000 ft (7.6 km) above sea level. Waythomas called the Great Sitkin eruption as "fairly passive," but he said if activity increases, Adak could get ashfall from Great Sitkin, located on an island about 27 miles (43.45 kilometers) away. Ash clouds were rising just above the volcanos 8,261-foot summit, drifting about 6 miles to the south before dissipating, Waythomas said.
