Humans persist in building centers of civilization in places of past disasters. We believe our technology will protect us next time. Yet we rarely win these battles with the earth because we don’t understand natural disasters deeply enough. Susan W. Kieffer has two goals for her unique book. The first is to show how the dynamics—the workings—of disasters are connected by a small number of natural laws. The second is to show that the most obvious process in a disaster is not always the one that causes the devastation. For instance, the transformation of apparently solid ground into a substance like quicksand during the 2010 Haiti earthquake is what caused the destruction of Port au Prince. Kieffer argues that only by truly understanding the dynamics of disasters can we begin to institute practices to minimize their impact on our lives.
