Why Study Natural Hazards?


Our main motivation is prediction: we wish to make informed and useful statements about the locations, impacts, magnitudes, and frequencies of natural hazards. Our current work is concerned with the prediction of landslides and their triggers; the impacts of explosive eruptions on steep, forested landscapes; how rivers respond to earthquakes; and the formation and failure of natural dams.
