Precursors of a Catastrophic Collapse

Ritter Island gives new insights into the dynamics of volcanic landslidesThe flanks of many island volcanoes such as Mount Etna or Mount Kilauea slide very slowly towards the sea. Whether these landslides are forewarnings of a catastrophic collapse or, on the contrary, even reduce its risk, is not yet understood. Geophysicists from the GEOMAR Helmholtz Centre for Ocean Research in Kiel have now published a study in the international journal Earth and Planetary Science Letters, which shows that sporadic, slow landslides on the small volcanic island of Ritter Island in New Guinea preceded a catastrophic collapse.
