| 摘 要： | 本文应用基于地震对应概率谱的多参数滑动极值相关度方法对郯庐断裂带进行时间和空间扫描计算.时间计算结果显示绝大多数目标地震发生之前均有高值异常现象出现；空间扫描计算结果显示中强地震前1年左右,震区及其附近区域多参数滑动极值相关度出现高值异常现象,且异常区域逐渐扩大增强,地震多发生在异常区域内或者附近.中强地震发生后,高值...

| Abstract: | Using the method of multi-parametric moving maximum probability based on earthquake corresponding probability spectrum,we try to temporal-spatially scan moderate-strong earthquakes of Tanlu fault zone.The temporal result shows that there are great changes of multi-parametric moving maximum probability before the target earthquakes.The spatial result shows that there are high anomaly phenomena near the epicentral area about 1 year before moderate-strong earthquakes.The high anomaly areas gradually enlarge and enhance and then earthquakes occur.About 1 year after moderate-strong earthquakes,anomaly areas dissipate,decrease or disappear.Generally,there are no high anomaly area of moving maximum probability in quiet periods. |
