| Zusammenfassung |
| The data base of technological accidents and disasters that have
occurred in Russia has been created. More than 13 000 information units have
been collected and analyzed. The proportion of accidents triggered by
natural events (natural-technological accidents or NTA) in the total number
of technological accidents as well as a part of every NTA type in the total
number of NTA was estimated. About 10 percent of all accidents registered in
the data base were caused by natural events; among some types of accidents
this proportion is even higher. Transmission facilities with more than 90
percent of overhead lines are the most vulnerable to the impact of natural
hazards. The contribution of different natural hazards was evaluated. Regions
with the greatest NTA risk were revealed. The influence of natural events on
the technosphere is stronger in the South of the European Russia and in the
Russian Far East, which are more exposed to hurricanes, snowstorms, rainfalls,
icing and other natural hazards producing NTA. The critical infrastructure
needs special protection and modernization in these regions. The problem
of the relationship between natural hazards and the technosphere is very complicated
and needs further investigation, especially taking the expected climate changes
into consideration. |
