摘要

研究了华南地区 14次中强地震前中等地震活动特征 ,据此提出了本区中强震短期预测判据 :中期 (或中短期 )中等地震累积频度呈指数 (加速 )增长 ,短期至发震中等地震持续平静 (通常小于 3个月 )。
In this paper, the characteristics of regional moderate earthquake (M L≥ 3.0) activity enhancement and quiet before 14 moderate-strong earthquakes in South China Area were studied . According to them, an index of prediction for moderate-strong earthquake is taken out: in middle term (or middle-short term) before the moderate-strong earthquakes, the accumulative frequency of moderate earthquake (M L≥ 3.0) in the abnormal area presents obvious non-linear exponent acceleration, in short term till main earthquake occurrence(usually no more 3 months), the moderate earthquake (M L≥ 3.0) activity presents abnormal quiet.
