STATISTICAL SIMULATION ANALYSIS ON THE PREDICTION ABILITY OF INDUCED EARTHQUAKES IN NORTH CHINA

the relationship of A-F-B earthquakes occurred in North China from 1970 to 1998 is studied with the method of the induced earthquake.The prediction ability of induced earthquakes is tested from statistical simulation.The results show that the occurrence probability of M_L≥5.9 earthquake is 32% within 200km in 3 years after an induced earthquakes occurred, which is higher than the sum of mean correlating rate and 3 times unbiased variance calculated from randomization.So the induced earthquakes contain some precursory information and have prediction ability in some extent.
