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 […]

Standing 9 kilometers tall from the base on the seafloor to the summit, Mauna Loa is the largest volcano on Earth. Credit: USGS Researchers find that a large earthquake could set off eruption of Hawaii’s Mauna Loa volcano. Scientists from the University of Miami (UM) Rosenstiel School of Marine and […]

Scripps Oceanography researcher’s assertion bolstered by series of new studies. New research lends credence to an unorthodox retelling of the story of early Earth first proposed by a geophysicist at Scripps Institution of Oceanography at UC San Diego. In a study published on March 15, 2021, in the journal Earth and […]
