THE ESTIMATION FOR RECENT SEISMIC RISK IN THE CONJUNCTURE AREA OF HEBEI, SHANXI AND INNER MONGOLIS

According to seismotectonics and microearthquakes stress field, the pracursor characteristics of the seis-micity from 1970 to 1936 in this area have been analyzed. After the extraction of the precursor information closely related to recent seismic risk, the synthetic evaluation for parameters his been proceeded by the fuzzy method. The possible risk probabilities of the various magnitudes have been given so as estimate the futira tendency.
