Abstract

Geodynamical variability is a cause of different natural disasters, such as earthquakes, volcanic eruptions, earthflows and seismic sea spillages. Natural disasters can activate technogenic catastrophes (building and construction failures, coal-mine explosions, dam integrity disturbance etc.). Technogenic catastrophes, in their turn, are able to originate such natural disasters as dam lake occurrence; the Earth crust’s surges with hazard consequences can be provoked by oil and gas extraction performance. Examples of natural disasters and technogenic catastrophes, factors of their origin, the phenomena prediction and avoidance recommendations have been shared in the following article.
