abstract: Nearly all models of earthquake preparation are known to indicate magnification of the collective component in the behavior of geophysical fields in the preparation zone as the moment the earthquake occurrence is approached. The geophysical monitoring is aimed at the detection of the so-called synchronization signal in variations of different geophysical parameters, as well as its duration and frequency range.
It is the synchronization and collective behavior of measured characteristics that are relevant to the problems of monitoring and preparation of an earthquake or other natural catastrophes. In this respect, certain methodological recommendations can be suggested which result from the most general regularities of the system behavior; we mean the regularities that draw a system nearer to a bifurcation, or catastrophe [Nicolis, Prigogine; 1989]. An increase in the fluctuation correlation radius in the bifurcation vicinity indicates that the system tends to be self-consistent throughout its volume, thereby preparing for the collective transition to a new state. In the statistical physics of fluids, such a behavior is known as “critical opalescence” or abnormal dispersion, and is considered as a universal signal of the approaching catastrophe.
