The invention relates to means of radio-physics for determination of ionospheric warnings of earthquake. Method for early prediction of earthquake includes measurement of total electronic content of ionosphere by means of GPS equipment, with study of character of change of total electronic content of ionosphere with respect to background level, determination of decrease of electronic concentration over epicenter region. By means of ion probe one performs measurement of critical frequencies of layer Fof ionosphere during time from 2to 4hours at night, this corresponds to interval of ion probe operation from 0 to t, at time interval from 0 to tmeasured values are collected, one calculates rate of change of squares of critical frequencies, at time interval from tto tone calculates extrapolated values of rate of change of squares of critical frequencies of layer Fof ionosphere, after that one performs calculation of coefficient of correlation between measured and extrapolated at time instants for interval from tto t, values of rate of change of square of critical frequencies of layer Fof ionosphere, at exceeding value of square of correlation coefficient between measured and extrapolated values of value 0.5, one makes conclusion on future earthquake that comes. The invention provides decrease of time for obtaining information on future earthquake that comes. |
