Kilauea Volcano’s 2018 eruption was triggered by a relatively small and rapid change at the volcano after a decade-long build-up of pressure in the upper parts of the volcano, according to a recent study published in Nature Communications by earth scientists from the University of Hawaii at Manoa and U.S. Geological Survey.
