Within the field of disaster studies there has always been the need to classify and label disasters. Researchers have distinguished between different types of disasters in terms of causes, outcomes, the element of surprise, scale, or scope. Chapter 2 discusses the pros and cons of the different classification systems, and also poses the question of whether it makes sense, in view of the large diversity of disasters, to study and compare these different types. Is it possible to move beyond the specificity of earthquakes or pandemics? We believe it does make sense. As historians, we can take a higher level of abstraction, revealing the similarities between different types of disasters. In order to understand why some societies coped more effectively with hazards and which characteristics were decisive in this, we can make use of various key concepts, namely disaster management, vulnerability, resilience, and risk. Overall, it is clear that hazards and disasters are not natural events but social processes.
