An 1888 Volcanic Collapse Becomes a Benchmark for Tsunami Models

by A. Micallef, S. F. L. Watt, C. Berndt, M. Urlaub, S.Brune, I. Klaucke, C. Böttner, J. Karstens and J. Elger 10 October 201718 November 2022

When volcanic mountains slide into the sea, they trigger tsunamis. How big are these waves, and how far away can they do damage? Ritter Island provides some answers.
