Abstract: The term "natural disasters" diminishes the key role that the human context plays in turning a natural event into a disaster. In this talk, I present scientific insights into the physical processes governing the onset and evolution of extreme events and discuss how this improved understanding the challenges and opportunities that these present for decision-makers and communities at risk. More specifically, I will focus on three disasters of special current relevance, ice-sheet disintegration, coastal risk and injection-induced seismicity. The common denominator of what at first glance might seem like disparate systems is multiphase flow. The dynamic interactions between multiple solid and fluid phases, such as ice and melt-water; vegetation and waves; rocks and wastewater; give rise to drastic nonlinearities that govern abrupt changes in system behavior reflected in extreme events.
