New in @science.org: Natural hazards aren’t “one and done.” They alter the landscape, changing the likelihood of follow-on events. We argue there’s an urgent opportunity for geomorphologists—working with other disciplines—to better understand and forecast cascading hazards.
Cascading land surface hazards as a nexus in the Earth system
This Review synthesizes progress and outlines a new framework for understanding how land surface hazards interact and propagate as sediment cascades across Earth’s surface, influenced by interactions ...
