Hawaii’s Mauna Loa, the world’s largest active volcano, has begun erupting for the first time since the 1980s, prompting authorities to put emergency crews on alert. The volcano began spewing lava and ash late Sunday. The U.S. Geological Service (USGS) said Monday the lava is contained within the summit and does not currently threaten residents […]
Magma beneath long-dormant Mount Edgecumbe volcano in Southeast Alaska has been moving upward through Earth’s crust, according to research the Alaska Volcano Observatory rapidly produced using a new method. The new approach at the observatory could lead to earlier detection of volcanic unrest in Alaska. At Mount Edgecumbe, computer modeling based on satellite imagery shows […]
The massive Jan. 15, 2022, eruption of the Hunga submarine volcano in the South Pacific Ocean created a variety of atmospheric wave types, including booms heard 6,200 miles away in Alaska. It also created an atmospheric pulse that caused an unusual tsunami-like disturbance that arrived at Pacific shores sooner than the actual tsunami. Those are […]
Satellite data can now routinely be used to detect low levels of sulfur dioxide emissions from volcanoes, giving scientists another tool to provide early warnings of volcanic unrest. The new approach is the result of work led by research assistant professor Taryn Lopez of the University of Alaska Fairbanks Geophysical Institute. Lopez is also a […]
