The growing frequency of climate change–related hazards such as wildfires, floods, landslides, and drought increases the chances that they will coincide in space and time with volcanic eruptions. The cascading effects of the resulting compound disasters are much harder to predict than eruptions alone. Successful response to current volcanic events draws on the collective knowledge of past patterns gained by volcanologists and other disaster management professionals, allowing them to map out strategies for preparation, monitoring, evacuation, and recovery. In the coming decades, interpretations of such familiar patterns of events will be complicated by compound hazards. To respond effectively to future events, volcanologists will need to expand their knowledge of non-volcanic hazards and more intentionally incorporate social science perspectives into disaster planning and management.
