Eruptive activity continued this week at the active north crater of Mount Cerberus, now known as Mount Young. A tsunami advisory was issued for parts of the U.S. Pacific coast Saturday morning after an undersea volcano erupted in spectacular fashion near Tonga. Contact Editor Andrew Kitchenman for questions: info@alaskabeacon.com. . But the implication is that dormant volcanoes might erupt again," Pyle said. The massive eruption, larger than the one on 14 January, generates an enormous amount of energy. 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. Numbers represent total earthquakes near that volcano for that week. In December 2021, a volcano in the Kingdom of Tonga, known as Hunga Tonga-Hunga Ha'apai, began erupting in an event that culminated in an explosion so powerful it sent atmospheric ripples circling the planet multiple times. The 2001 eruption also produced a lava flow and hot avalanche that reached the sea. Its also based on how close a volcano is to homes, businesses and structures. Due to a reduction of volcanic unrest at Cleveland Volcano over the past few months, on Thursday Alaska Volcano Observatory downgraded the Aviation Color Code and Volcano Alert Level from YELLOW/ADVISORY to UNASSIGNED/UNASSIGNED. Meanwhile, Pavlof Volcano on the Alaska Peninsula is also producing ash clouds. The activity from the Hunga Tonga-Hunga Ha'apai volcano continued into Saturday morning with another, less powerful 10- to 15-minute-long eruption, according to the Tonga Geological Service. In an October paper published in the journal Geophysical Research Letters, scientist Ronni Grapenthin noted that the ground on the east side of the volcano was bulging outward at a rate faster than any other volcano in Alaska. Carefully reviewed, detailed narratives over longer time periods are published as reports of the Bulletin of the Global Volcanism Network available through volcano profile pages. February 27, 2023 by James Brooks, Alaska Beacon. Pavlof Volcano is a snow- and ice-covered stratovolcano located on the southwestern end of the Alaska Peninsula about 592 mi (953 km) southwest of Anchorage. Tsunami waves surged ashore the coast of Tonga on Jan. 15 after the Hunga Tonga-Hunga Haapai volcano erupted about 40 miles north of the Pacific nation.

Satellite images were mostly cloudy during the last 24 hours. The volcano has been erupting sporadically since 2018 and activity has been characterized by eruption of ash to heights usually less than 10,000 ft (3 km) above sea level. They said theyre not concerned by the volcanos movement or the distant prospect of an eruption. But for all the devastation that it caused, it wasn't actually that big an eruption, compared to those of the last century. It's easy to understand why: one of those volcanoes has had a major eruption within living memory (Mount St. Helens in 1980) and the Cascades loom over some major population centers along the. Officials at the observatory have been paying greater attention to Edgecumbe since April last year, when a swarm of small earthquakes brought attention to the volcano, which had been considered dormant. So far, none of the small communities near the volcanoes have been affected, Chris Waythomas, a geologist with the Alaska Volcano Observatory, said Thursday. Pavlov last erupted in 2016, dropping some ash on another community, Nelson Lagoon. Scientists will often record really low-frequency sound waves around the world following big volcanic eruptions or explosions, but its quite rare to be able to hear them audibly, he said. Infrasound measurements from the @alaska_avo confirm that it was indeed coincident with the volcanic pressure wave. The observatory on Thursday received reports from people in the community of Adak of a lava fountain at the summit of the Great Sitkin volcano. Rapid detection of an ash-producing eruption may be possible using a combination of seismic, infrasound, lightning, and satellite data. As a result, many have described it as being "dormant.". Lava continued to erupt within the summit crater of Great Sitkin Volcano this week. Legal Statement. The observatory on Thursday received reports from people in the community of Adak of a lava fountain at the. On 7 August 2008, Kasatochi began erupting explosively with an ash plume reaching 45,000 feet. Ash clouds were rising just above the volcanos 8,261-foot summit, drifting about 6 miles to the south before dissipating, Waythomas said. A high-resolution satellite image from Monday showed continued slow growth of the lava flow field. "Detecting magma movement at depth is usually a reminder that a volcano is active, or potentially active, but it isn't necessarily a sign that a volcano will erupt," Pyle said. There are no written accounts of eruptions from Mount Edgecumbe, but Tlingit oral tradition calls Lx Shaa (the original name of Edgecumbe) a mountain blinking, spouting fire and smoke about 800-900 years ago. The Alaska Volcano Observatory is a cooperative program of the U.S. Geological Survey, the University of Alaska Fairbanks Geophysical Institute, and the Alaska Division of Geological and Geophysical Surveys.

The Alaska Volcano Observatory is planning to install a series of seismic instruments on Mount Edgecumbe near Sitka afterpreliminary measurementsshowed magma moving deep below the Mount Fuji-shaped volcano. Mount Edgecumbe is now considered a high risk volcano, one step below the states very high risk volcanoes: Augustine, Spurr, Redoubt, Akutan and Makushin. In Tonga it sent tsunami waves crashing across the shore and people rushing to higher ground. But more than 50 years prior, Alaska was also home to the world's largest volcanic eruption of the 20th century. If the gas bubbling through the lakes is magmatic, she said, itll be another sign of activity at the volcano. The most recent eruption began in December 2021, with gas, steam, and ash plumes rising about 12 kilometers (7.5 miles) into the air. The largest earthquake during the last 24 hours was M3.1. Mount. 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. The movement doesnt mean an eruption will happen soon or even at all from Southeast Alaskas most prominent volcano, but its significant enough that the observatory has raised the volcanos threat level. Great Sitkin Volcano is monitored by local seismic and infrasound sensors, satellite data, web cameras, and regional infrasound and lightning networks. Anew information update, released Friday, shows the earthquakes have continued, hikers have observedgas bubbling from the groundnear the volcano, and satellite radar measurements show the ground around the volcano bulging upward.

The U.S. Geological Survey has estimated that there are 161 potentially active volcanoes in the country, although only 42 of these have been active in the last 70 years. Increases in seismic activity have been detected previously atTridentVolcano and other similar volcanoes, with no subsequent eruptions. All rights reserved. "'Dormant' is a word that is often used to describe volcanoes that haven't erupted for decades or centuries, and perhaps look completely quiet. No ash plumes have been observed in web camera or satellite imagery, but a persistent steam plume rising up to 5,000 ft above sea level from the active crater may now be carrying minor volcanic ash within it. I think the science is behind it. Crustal seismicity in this region can be attributed to the Kodiak Shelf Fault Zone and to the volcanic arc. The US and Japan have advised people on their Pacific coastlines to get away from the shore as a precaution against tsunami waves caused by a volcano eruption in the South Pacific. 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. And we can combine this with earthquake locations to work out in three dimensions the shape of the magma body inside the Earth.". The volcano is dominated by a 5-mile (8 km) diameter caldera that contains a small lake and several post-caldera cones and craters. Mutual Fund and ETF data provided by Refinitiv Lipper. The impact of volcanic eruptions can be felt from hundreds of miles away.

The volcano is located about 45 miles (75 km) west of the community of Nikolski, and 940 miles (1500 km) southwest of Anchorage. All of them occurred at with depths less than 6 miles (9 km) below sea level. No significant seismicity was observed over the past day. The observation of ash deposits this week was accompanied by periods of elevated seismicity and infrasound signals observed on the local geophysical network, which were likely due to weak explosive activity. published in the journal Geophysical Research Letters, scientist Ronni Grapenthin noted that the ground on the east side of the volcano was bulging outward at a rate faster than any other volcano in Alaska. In the center of the Aleutian Islands, about 26 miles northeast of Adak, Great Sitkin volcanoerupted at the end of May. The fact that the explosion happened beneath the sea likely contributed to the explosiveness, but not how far the sounds traveled, Fee said. It almost sounded like someone was walking outside or something, he said. 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.
