METHOD OF DETERMINING CHARACTERISTICS OF EARTHQUAKES Russian patent published in 2009 - IPC G01V9/00 

FIELD: physics; mining.

SUBSTANCE: ascending SHF-radiation of the Earth is received by an instrument, installed on the space vehicle, on two mutually orthogonal polarized reception channels. The beginning of change in radiation polarisation in reception channels is recorded along with its variation all along the flight path. Note here that reception is executed by two spiral aerials of the LH and RH directions of polarisation rotation. A difference between polarisations in reception channels is extracted with the help of phase detector. Note here also that the second reception channel signal shifted in phase through π/2 makes the reference signal for aforesaid phase detector. The earthquake seismic hypocenter is compared with a point of the record graph maximum curvature. Record graph curve (l) length variation is recorded for consecutive space vehicle orbits above and over the zone of expected earthquake and time constant (T) of the rate of variation of aforesaid length is determined. Now, the probable time and magnitude of the earthquake is forecasted.

EFFECT: increase in forecast accuracy.
