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.

Key words: Multi-parametric moving maximum probability, Integrated Anomaly, Temporal-spatial anomaly characteristics, Tanlu fault zone
