【摘要】 研究了永登５．８级地震前地震活动异常特征，并应用秦保燕提出的地震动态空区的原理和地震频次起伏加剧，研究了１９９５年永登５．８级地震的孕震过程，对地震三要素进行了回顾性预报。结果表明，预测结果与实际地震发生的时间、强度和地点十分接近更多还原

【Abstract】 In this paper, the principle and formula of dynamic gap method raised by prof. Qin Baoyan are applied to study the earthquake generating process and to determine the three elements of earthquake prediction about the Yongdeng M S 5.8 earthquake in 1995. The results are very close to reality.更多还原
