a series of M7+ earthquakes was associated . Since then, Cleveland has been intermittently active producing small lava flows, often followed by explosions that generate small ash clouds generally below 20,000 ft (6 km) above sea level. Risk isnt just the likelihood of an eruption, Coombs said. Hannah Dietterich, a research geophysicist with the Alaska Volcano Observatory, said three simultaneous eruptions may seem like a lot, but itsnot unheard of for the region. 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. Weakly elevated surface temperatures and minor steaming from the active vent were observed in satellite data and web camera views several times during the week and may be related to the cooling of lava around the vent. Satellite images and web camera views were mostly cloudy during the last 24 hours. In Tonga it sent tsunami waves crashing across the shore and people rushing to higher ground. Active lava.

If the gas bubbling through the lakes is magmatic, she said, itll be another sign of activity at the volcano. About the same time, the observatory will be placing three or four additional instrument stations on the volcano. The current period of seismic unrest began on August 24, 2022. 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. In volcano preparedness, knowing where the next socially disruptive eruption may take place is half the battle. If the gas bubbling through the lakes is magmatic, she said, itll be another sign of activity at the volcano. Makushin Volcano is Unalaska Island's highest peak and one of the most active volcanoes in Alaska. If it does erupt, we expect a lot more activity before that happens, said Michelle Coombs, a USGS geologist and scientist-in-charge at the Alaska Volcano Observatory. Alaska contains over 130 volcanoes and volcanic fields which have been active within the last two million years. Increases in seismic activity have been detected previously at other similar volcanoes, with no subsequent eruptions. 2023 FOX News Network, LLC. He said if activity increases, Adak could get ashfall from Great Sitkin, located on an island about 27 miles away. Low-level volcanic tremor was detected in seismic data over the past day. 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. A veteran of AmeriCorps and Vista volunteer programs, she's previously reported for Mission Local and KQED in the Bay Area. There were just a few other times Fee could think of when audible sound traveled so far and wide, including the Novarupta Katmai eruption of 1912, the largest eruption of the 20th century, and the 1883 Krakatoa eruption.

The volcano is located about 45 miles (75 km) west of the community of Nikolski, and 940 miles (1500 km) southwest of Anchorage. AVO analysts located 17 small earthquakes (less than magnitude 1.5) during the last 7 days. Partially because of their experience, Kluting and Turley have been following events more closely than most. 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. 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). The last eruptive activity at Cleveland volcano was a short-lived explosion on the evening (local time) of June 1, 2020. The reports were later confirmed by webcam.

The volcano is dominated by a 5-mile (8 km) diameter caldera that contains a small lake and several post-caldera cones and craters. Low-frequency sounds typically travel greater distances than audible sounds because they lose energy at a lower rate. It was deeper., [Correction: This story was updated to clarify that audible sounds from the eruption lasted about 30 minutes while lower-frequency sounds lasted around two hours.]. Its also based on how close a volcano is to homes, businesses and structures. Great Sitkin Volcano is monitored by local seismic and infrasound sensors, satellite data, web cameras, and regional infrasound and lightning networks.
