METHOD FOR PREDICTING EARTHQUAKES Russian patent published in 2004 - IPC

FIELD: geophysics.

SUBSTANCE: method includes performing synchronous measurements of intensiveness of natural Earth impulse electromagnetic fields in several points of controlled region. Measurements in each point are performed in no less than two different directions of signals receiving. Sensitivity of registering station is selected in accordance to local geophysical conditions, in such a way, that intensiveness of natural Earth impulse electromagnetic fields registered by station was close with its values to intensiveness of typical day change of natural Earth impulse electromagnetic fields. Abnormal territory is singled out on basis of presence of fast changes of natural Earth impulse electromagnetic fields intensiveness in comparison to day variations of natural Earth impulse electromagnetic fields measured a day before or in earlier years in same calendar dates, in relatively calm seismic periods. Position of center of predicted earthquake is matched with coordinates of point in central portion of abnormal territory and characterized by strongest and earliest changes of natural Earth impulse electromagnetic fields intensiveness. Start of earthquake is predicted in 10-15 days after start of registration of fast changing natural Earth impulse electromagnetic fields intensiveness. Energetic class K of predicted earthquake is evaluated.

EFFECT: more precise prediction of time, energy and coordinates of center of expected earthquake.
