METHOD OF PREDICTING EARTHQUAKES Russian patent published in 2006 - IPC G01V9/00

Abstract RU 2273869 C1

FIELD: geophysics.

SUBSTANCE: method can be used in national seismic inspection systems. Phase correction ▵Φ for radio signal propagation time in plasma medium of ionosphere is measured when calculating pseudorange in GPS. Dispersions of mentioned parameter are tracked at ascending and descending turns of orbit of spaceship from several points of location finding. Characteristics of coming blow are predicted by function of change in dispersion envelope of parameter to be observed in time.

EFFECT: improved precision of forecast; improved truth.
