A new analysis of the deadly Anak Krakatau flank collapse

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

One of the most deadly hurricanes of modern times was Hurricane Mitch, which tracked across Central America in late October 1998. Many of the tens of thousands of victims were killed by landslides.
