Ritter Island (VIDEO)
Caption
The 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. The study is based on an expedition with RV SONNE to Ritter Island in 2016.
