Natural hazards as pre-conditions of technological disasters in Russia

A database of Russian technological disasters (1992-2006) has been created for the first time. Using collected data the most important types of disasters for Russian federal regions were identified and classified; two types of natural hazards affecting them have been found. Factor analysis revealed two corresponding groups of technological disasters with similar temporal distribution. Twelve types of technological disasters resulting from direct mechanical impacts of various natural hazards have been found for Russian federal regions. Natural hazards causing technological disasters have been also divided into 12 groups according to their genesis. The investigation of interrelationships between technological disasters and natural hazards at the regional level revealed 12 types of natural-technological events (na-techs). The map of na-techs occurring in Russian federal regions has been created for the first time.
