DESTRUCTION ZONES AS A SOURCE OF ANOMALIES OF GEOPHYSICAL FIELDS

Geophysical monitoring of geological environment is one of the main directions of geodynamic studies,
which allows you to monitor remotely the processes in the Earth’s crust. The investigation results of the phys-
ical fields produced by the lithosphere due to seismic activity, show that the change in geodynamic conditions
in transitional zones of lithospheric plates is reflected in the variations of magnetic, gravitational, electrical
and electromagnetic fields. The scales of manifestations of physical field anomalies range from local, during
the change of a seismic regime in the vicinity of observation points, to global, during the formation of foci of
catastrophic earthquakes. Study of variations of physical fields in connection with seismicity indicate that the
spatial period of manifestations of anomalies greatly exceeds the area covered by the experimental basis. Study
of variations of physical fields in southern Yakutia showed that geophysical anomalies of global environment are
produced the most intensively in the zones of destructive dynamic of mature fields, the dynamic effects of gen-
eral faults. These regions of the Earth crust with high seismic potential should be considered the single source
of physical field anomalies. Change of the force of gravity, magnetic, electromagnetic and other fields can be re-
duced to a single problem of production of geophysical fields as a result of the dynamics of charged fluid motion.
