摘要
Using the method of multi-parametric moving maximum probability based on earthquake corresponding probability spectrum, the authors try to temporal-spatially scan moderate-strong earthquakes of Tancheng-Lujiang 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.
