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 […]
Some Alaskans have the dubious distinction of a volcano practically in their backyard, across the water or upwind. Now, a new radio program will help keep them, and other listeners across the state, informed about what’s going on with Alaska’s 54 active volcanoes.

Officials in Hawaii have called for more evacuations after an 18th fissure spewing lava from the Kilauea volcano was discovered Sunday on the Big Island. “The amount of lava that has erupted from the fissure so far is very, very small,” said scientist Steve Brantley of the U.S. Geological Survey’s Hawaiian Volcano Observatory. Exploding and […]
Among the most feared events in space physics are solar eruptions, massive explosions that hurl millions of tons of plasma gas and radiation into space. These outbursts can be deadly: if the first moon-landing mission had encountered one, the intense radiation could have been fatal to the astronauts. And when eruptions reach the magnetic field […]
