摘    要:基于地震学多参数的地震对应概率谱(ECRS)方法及此前研究成果,对郯庐断裂带中段和南段(中南段)至2015年9月份的地震异常特征进行了跟踪研究。时间跟踪研究结果表明,目标地震均在震前出现多参数的综合高值异常,且目前其综合指数处于异常上升状态。空间跟踪研究结果同样显示,研究区目标地震发生前大多有高值异常出现并逐渐增强,地震多发生在异常区域内或者附近。

关 键 词:多参数滑动极值相关度  时空计算  郯庐断裂带中南段

Abstract:Using the method of multi-parametric maximum probability based on Earthquake Corresponding Probability Spectrum(ECRS)and previous research results,this paper studied the earthquakes of the middle and southern parts of the Tancheng-Lujiang fault zone up to September,2015. The results of time tracking found that there are high anomaly values before almost all target earthquakes. However,the composite index is in a rising state. Spatial calculating results also confirmed the high anomalies before target earthquakes,and that the earthquake occurred in the abnormal area or nearby.
Keywords:Multi-parametric moving maximum probability  Temporal-spatial calculating  Middle-south part of Tancheng-Lujiang fault zone
