When I looked at the data this morning, it was pointing back at that volcano. Rapid detection of an ash-producing eruption may be possible using a combination of seismic, infrasound, lightning, and satellite data. Mutual Fund and ETF data provided by Refinitiv Lipper. ALASKA VOLCANO OBSERVATORY WEEKLY UPDATE 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. No eruptive activity was observed over the past week and no explosions have been detected since December 7, 2022. Tech & Science Alaska Volcano Eruption Science Activity has been detected under a dormant volcano near Sitka, Alaska. When another batch of magma rises up beneath the volcano, then we might see the volcano becoming restless once again, or 're-activated.'". Pavlov is a very sneaky volcano, Waythomas said.

During an ongoing eruption, AVO will update the forecast with actual observations (eruption start time and duration, plume height) as they become available. More ash-producing events could occur again with little warning. 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. 2. Great Sitkin Volcano is monitored by local seismic and infrasound sensors, satellite data, web cameras, and regional infrasound and lightning networks.

It definitely has moved up, said Cheryl Cameron, a state geologist who works at the volcano observatory. . 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. Takawangha's summit is mostly ice-covered, except for four young craters that have erupted ash and lava flows in the last few thousand years. Mutual Fund and ETF data provided by Refinitiv Lipper.
