The methodical tools of calculation of power ecological consequences at influence of emergency situations of natural genesis are presented in article. The main are considered a tendency of development of natural disasters in continents of the world; it is established that since the beginning of 21 century there was gradual growth of number, the victims from natural emergencies, and also material damage, having reached the maximum values in 2011. The following indicators of power ecological consequences of natural emergencies – the full, useful power, emergency power, anthropogenous loading and instability of the biosphere on continents of the world are calculated; it is established that for one of continents of the world anthropogenous loading isn’t in norm limits. The presented schematic map of instability of the biosphere of continents of the world for 2011 demonstrated that in general in the world there was a difficult situation in respect of instability of the biosphere exceeding all threshold values.
KEYWORDS: natural disasters, power ecological consequences of accidents, power of accidents, anthropogenous loading, instability of the biosphere on continents of the world.
