Add as preferred source The two glaciers around the Beerenberg volcano after the rock avalanche: Triggered by a 6.5-magnitude earthquake, large quantities of volcanic and permafrost debris tumbled down at the Kjerulf Glacier, spreading the material across the surface and covering the ice right up to the coast (left side of the picture). Credit: Grace Angelo Permafrost refers to permanently frozen ground. The rock is held together by ice, much like cement binds concrete. However, when the ice thaws, the ground becomes weak and unstable. During an earthquake, this can trigger a series of natural hazards. An international research team investigated precisely such an event.
