What Caused the Fatal 2014 Eruption of Japan's Mount Ontake?

by Terri Cook 17 March 20176 December 2021

Analysis of the change in the stratovolcano's tilt just prior to the explosion suggests that the cracking of a previously intact fluid barrier caused the country's deadliest eruption since 1926.
