Abstract

A physical-mathematical model and approaches to the measurement of the integral earthquake precursor proposed in the form of a theoretical scheme are developed by authors in previous papers. This model can probably reduce the acuteness of contradictions which often take place between precursors of different physical nature when a multidisciplinary model of prediction is used.

Reasons for the choice of the space-time density of cracks as an integral earthquake precursor in the area of preparing earthquake source and in the zone of appearance of anomalous geophysical fields are given.

The possibility of formation of near-surface migrating dilatant zones that can cause variations of geophysical fields-precursors is shown. This conception gives new possibilities to the determination of an integral earthquake precursor.

Schemes for quantitative estimation of the integral precursor using seismic and combined (multidisciplinary) inverse problems for fracturous media are proposed.
