And the local population remains in constant stress because no one can tell them when the next fatal blow will strike.

Prognostication of earthquakes is now on the agenda." Statements of this kind can be heard to this day even despite the obvious lack of any tangible progress. Some of the more far-sighted experts, like Acad. Vladimir Strakhov, point out that prognostication means building a stable whole from a number of unstable components. In his view a comprehensive prognostication of earthquakes at the present time is impossible. An even more categorical view belongs to RAS Corresponding Member, Alexei Nikolaev: "One can see even now that the problem of earthquake prognostication will never be fully resolved in a determined way-nature always has several scenarios in store and any of them can be chosen." But many geophysicists do not give up hopes. They point out that during earthquakes the earth crust cracks up, like china tableware. Stresses within it are accumulated until a rupture is formed at ... Читать далее
