Low-level volcanic tremor was detected in seismic data over the past day. Three volcanoes on a remote Alaskan island chain have been erupting simultaneously for almost two weeks. Risk isnt just the likelihood of an eruption, Coombs said. 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. The most recent significant period of eruption began in February 2001 and produced 3 explosive events that generated ash clouds as high as 39,000 ft (11.8 km) above sea level. Research carried out by the Alaska Volcano Observatory in collaboration with the Alaska Satellite Facility used mathematical modeling based on satellite imagery to determine that this recent increase in seismic activity had been caused by the upward thrust of moving magma deep under the earth's surface. Cleveland volcano forms the western portion of Chuginadak Island, a remote and uninhabited island in the east central Aleutians. No eruptive activity was observed over the past week and no explosions have been detected since December 7, 2022. AVO noted that there was no indication that an eruption of Aniakchak was imminent, or that one will 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. Thats why you can hear the bass from a concert or stereo much further away, Fee explained. 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. Activity has been detected under a dormant volcano near Sitka, Alaska. This Act renamed Mount Cerberus to Mount Young in honor of long-time Alaska Congressman Don Young. Our latest update is really just saying, Hey, this unrest is still going on. A new information update, released Friday, shows the earthquakes have continued, hikers have observed gas bubbling from the ground near the volcano, and satellite radar measurements show the ground around the volcano bulging upward. 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. These explosions also launch debris onto the slopes of the cone producing hot pyroclastic avalanches and lahars that sometimes reach the coastline. No historical eruptions are known from Takawangha; however, field work shows that recent eruptions have occurred and it is possible that historic eruptions attributed to Tanaga may instead have come from Takawangha. Infrasound measurements from the @alaska_avo confirm that it was . Edgecumbe in Sitka in this 2011 photo. These stations will use GPS to track the volcanos continued expansion, and their seismographs will allow scientists to triangulate the small earthquakes that take place within the volcano as magma moves around. "This lava fountain is kind of unusual for Great Sitkin, but its been fairly passive at this point," said Chris Waythomas, a geologist with the Alaska Volcano Observatory. The current period of seismic unrest began in October 2022. It might not erupt.

Kasatochi Island (Aleut: Qanan-tanax; Russian: ), also known as Kasatochi volcano, is an active stratovolcano and part of the Andreanof Islands subgroup of the Aleutian Islands of southwestern Alaska. The fact that the explosion happened beneath the sea likely contributed to the explosiveness, but not how far the sounds traveled, Fee said. Low-frequency sounds typically travel greater distances than audible sounds because they lose energy at a lower rate. The eruption started almost two weeks ago and have steadily grown stronger, but they do not yet pose a concern to experts. And then they may fall dormant again between eruptions, as the magma cools down. Lingit Aani Kaa Kei Nas.ax Haa Yoo Xatangi. I guess I trust the science on it, Kluting said. The fact that Alaskans could hear any kind of sound was indicative of just how large this volcanic eruption really was, he said.

Its initial eruption produced a plume of volcanic ash and . Minor steaming from the summit crater was observed over the past week but is considered to represent background activity for Cleveland. The eruption destroyed much of the volcanic peak . near the volcano, and satellite radar measurements show the ground around the volcano bulging upward. 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. Officials at the observatory have been paying greater attention to Edgecumbesince April last year, when a swarm of small earthquakes brought attention to the volcano, which had been considered dormant. Numbers represent total earthquakes near that volcano for that week. AVO monitors Aniakchak with a local network, which consists of six seismometers, a web camera, and a single infrasound sensor, as well as satellite remote sensing data and regional infrasound and lightning networks. The latest of the trio of supervolcano eruptions created the park's huge crater, measuring 30 by 45 miles across (48 by 72 kilometers). Early data suggests the volcanic . A steep-sided lava dome, emplaced during the most recent significant eruption in 1974, occupies the center of the crater. Of these volcanoes, about 90 have been active within the last 10,000 years (and might be expected to erupt again), and more than 50 have been active within historical time (since about 1760, for Alaska). about 150 years ago. The most recent eruption began in December 2021, with gas, steam, and ash plumes rising about 12 kilometers (7.5 miles) into the air. These occur without warning and typically generate small clouds of volcanic ash that are a hazard in the immediate vicinity of the volcano, though more significant ash emissions are possible.
