Keywords: Statistics of natural disasters, the historical role of strong earthquakes, the vulnerability of societies.
Аnnotation: A brief review of the main results of the study of the statistics of damage from natural disasters, in particular, from strong earthquakes, is given. Attention is drawn to a certain discrepancy between the statistics of catastrophes, indicating the possibility of the occurrence of rare earthquakes with especially heavy damage values, and the practice of underestimating this factor in historical research. Examples of the decisive impact of strong seismic catastrophes of the past on the history of a number of human societies are given. In combination with other factors these catastrophes had caused even a change in the nature of land use from irrigated agriculture to nomadic animal husbandry. It is also noted that the level of damage from natural disasters can characterize not only the strength of natural impacts, but also the increase in vulnerability of human societies to strong external impacts, that is characteristic of crisis periods.
