【摘要】 加卸载响应比理论是描述震源区介质损伤程度的一种地震预测方法。基于加卸载响应比理论,对2016年11月25日阿克陶M_S6.7地震前加卸载响应比时空演化特征和异常区的孕震积分时程曲线进行分析。结果表明,本次地震前,研究区出现了多个加卸载响应比高值区域,异常区呈现为环状或片状,随着地震孕育过程,异常区往震源附近迁移,发震地点在异常区边缘和内部,地震发生在异常高值减弱过程中,异常峰值到发震时间为1个月,远小于理论发震时间,这表明了研究区构造活动剧烈,孕震周期短的特征。更多还原

【Abstract】 The load/unload response ratio（ LURR） theory is a method for predicting earthquakes by characterizing the extent of damage in the focal area.Based on the load/unload response ratio theory,the spatial-temporal evolution characteristics of LURR abnormality before the Aketao earthquake with M_S6.7 occurred on November 25^th,2016 were analyzed,and seismogenic integral of abnormal area was analyzed.The results showed that there were many LURR abnormal areas in study area before Aketao earthquake with M_S6.7,and anomaly area was annular or flaky.Before incoming earthquake,anomaly zone migrated to vicinity of source,in process of abnormal high value weakening,the peak value to earthquake occurrence time was one month,which was far less than theoretical occurrence time.This showed that tectonic activity in study area was intense,and seismogenic preparation period was short.更多还原
