This visualization shows the approximate location of an avalanche of hot ash and volcanic gas flowing down Indonesia’s erupting Mount Merapi volcano on October 30, 2010.
A jumble of hot ash, rock, and soil poured down the slopes of the Guatemalan volcano in early June. Weeks later, satellites continued to detect elevated temperatures in the thick deposits.
A thick plume of ash rose from Mount Merapi on November 10, 2010, when this photo-like image was taken. It is the most cloud-free image of the eruption to date.
