Аннотация:The natural and social disasters generate a huge stress in the world community. Most researches
searching for the relationships between different catastrophic events consider the limited sets of
disasters and do not take into account their size. This fact puts to doubt the completeness and
statistical significance of such approach. Thus the next indispensible step is to overpass from
narrow subject framework researches of disasters to more complex researches.
In order to study the relationships between the Nature and the Society a database of natural
disasters and dreadful social events occurred during the last XXXVI (36) centuries of human history
weighted by the magnitude was created and became a core of the GIS «Disasters» (ArcGIS 10.0). By
the moment the database includes more than 2500 most socially significant ("strong") catastrophic
natural (earthquakes, fires, floods, droughts, climatic anomalies, other natural disasters) as well
as social (wars, revolts, genocide, epidemics, fires caused by the human being, other social
disasters) events. So far, each event is presented as a point feature located in the center of the
struck region in the World Map. If the event affects several countries, it is placed in the
approximate center of the affected area. Every event refers to the country or group of countries
which are located in a zone of its influence now. The grade J (I, II and III) is specified for each
event according to the disaster force assessment scale developed by the authors. The GIS with such
a detailed database of disastrous events weighted by the magnitude over a long period of time is
compiled for the first time and creates fairly complete and statistically representative basis for
studies of the distribution of natural and social disasters and their relationship.
By the moment the statistical analysis of the database performed both for each aggregate (natural
disasters and catastrophic social phenomena), and for particular statistically representative types
of events led to the following conclusions: natural disasters and dreadful social events have
appeared to be closely related to each other despite their apparently different nature. The numbers
of events of different magnitude are distributed by logarithmic law: the bigger the event, the less
likely it happens. For each type of events and each aggregate the existence of periodicities with
periods of 280 ±60 years was established. The identified properties of cyclicity, grouping and
interaction create a basis for modeling essentially unified Geosocial Process at a high enough
statistical level and prove the existence of the uniform planetary Geosocial Process. The evidence
of interaction between "lifeless" Nature and Society is fundamental and provided a new forecasting
approach of demographic crises taking into account both natural disasters and social phenomena. The
idea of the interaction of Nature and Society through the disasters «exchange» as a uniform
planetary Geosocial Process is an essentially new statement introduced for the first time.
