Spaceflight Now NASA satellite looks at menacing glacier in Peru: "Glacial flood-bursts, known by Peruvians as 'aluviones,' occur periodically when water is released abruptly from a previously ice-damned lake alongside, within or above a glacier. The release can be caused by various triggering events. These flood-bursts typically arrive with little or no warning, carrying liquid mud, large rock boulders and blocks of ice." Mudslides probably cause more damage than earthqaukes themselves.
