Beneath dormant volcanoes in the Cascades region of the Pacific Northwest, scientists found large reservoirs of magma. The discovery challenges the belief that active volcanoes have large magma bodies that are released during eruptions and then gradually disappear as the volcanoes enter a dormant state. In a new study, researchers used seismic waves to identify magma chambers beneath six volcanoes within the Cascade Range. The volcanoes varied i…
