The archaeology of disasters: Past and future trends

In a landmark book which examined the role of volcanic eruptions in human evolution, Sheets and Grayson (1979: 6) could legitimately note that very few archaeologists had paid significant attention to the potential cultural effects of the natural hazards (e.g. volcanic tephra, earthquake-damaged walls, etc.) whose occurrences were apparent from many of their excavations. The current situation is radically different. In recent years studies stressing the impacts of past natural disasters on ancient societies have increased dramatically, although the majority of these are still authored or inspired by natural scientists and astronomers rather than archaeologists (e.g. Ambrose, 1998; Driessen and Macdonald, 1997; Harris, 2000; Isaacson and Zeidler, 1999; McGuire et al., 2000; McCoy and Heiken, 2000; Newhall et al., 2000; Nur and Cline, 2000; Peiser et al., 1998; Siebe et al., 1996; Stiros and Jones, 1996). Volcanic eruptions have led the way as the most commonly invoked environmental forcing mechanism, but droughts, floods and earthquakes are now also regularly proposed as triggering cultural change.
