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 […]
High on the broken pyramid of Iliamna Volcano, rotten rock held in place by volcano-warmed ice sometimes loses its grip. Several times over the years, rock-and-ice avalanches have blasted down Iliamna at 150 miles per hour. Left behind on the mountain’s face is a dirty, five-mile scar, in the same place as the last one. […]
There isn’t much in Kamchatka, a remote peninsula in northeastern Russia just across the Bering Sea from Alaska, besides an impressive population of brown bears and the most explosive volcano in the world. Kamchatka’s Shiveluch volcano has had more than 40 violent eruptions over the last 10,000 years. The last gigantic blast occurred in 1964, […]
The Alaska Volcano Observatory reports continued seismic activity at the Korovin volcano site on Atka. They say no other significant activity has been reported since sulfur dioxide emissions were detected on Wednesday. The 5,030-foot stratovolcano, with its two summits, is monitored by seismic networks, infrasound sensors and watched via satellite data. The seismic activity […]
