Agung, a volcano in Bali, had an explosive eruption in 2018. Credit: O.L. Andersen Indonesia’s volcanoes are among the world’s most dangerous. Why? Through chemical analyses of tiny minerals in lava from Bali and Java, researchers from Uppsala University and elsewhere have found new clues. They now understand better how […]

Eruptions from […]

NASA’s Galileo spacecraft caught Jupiter’s moon Io, the planet’s third-largest moon, undergoing a volcanic eruption. Locked in a perpetual tug of war between the imposing gravity of Jupiter and the smaller, consistent pulls of its neighboring moons, Io’s distorted orbit causes it to flex as it swoops around the gas […]

Photo of eruption at Mount Redoubt in Alaska in 2009. Credit: Game McGimsey, USGS New research methods may lead to earlier predictions of volcanic eruptions. Although there are telltale signs that a volcano is likely to erupt in the near future – an uptick in seismic activity, changes in gas […]
