While research communities are trying to better understand complex, compounding and cascading disasters, the Hunga Tonga-Hunga Ha’apai eruption and tsunami in January 2022 devastated Tonga’s emergency management system.

Natural hazards often occur simultaneously or successively, resulting in complex, compounding and cascading impacts that interact. Climate change may increase both compound and cascading hazards in the future, and as such, knowledge on how these impacts interface is crucial for reducing disaster risk.
