A paper (Williams et al. 2019) published in the journal Geology provides an analysis of the deadly 2018 Anak Krakatau flank collapse. Interestingly, the landslide was surprisingly small to have generated such a large tsunami.

The Casita landslide revisited

Volcanic flank collapse and tsunamis

A few years ago the media got rather excited about a paper that suggested that there was the potential for a giant flank collapse on the Cumbre Vieja volcano in the Canary Islands. A model of the resultant tsunami suggested that it could be sufficiently large to cause huge losses throughout the coastal areas of the North Atlantic. Most scientists now believe that this tsunami was something of an exageration …
