郯庐断裂带南段加卸载响应比变化特征分析

Abstract

Abstract: In this paper, we studied the variation of load-unload response ratio (LURR) in the southern Tanlu fault zong, and summarize the timing curve characteristics before some significant earthquakes in this area. The results reveal that the load-unload response ratio, which represents the extent of the subsurface damage, has a clear physical meaning and can give good results in practical applications. It was found that LURR has short-term high value anomaly before some significant earthquakes in the areas of high seismic activity level of medium and small earthquakes. However, LURR mainly shows long-term background high value anomalies in other areas.

Key words: Load-unload response ratio (LURR), Timing curve characteristics, Scanning window length, Southern Tanlu fault zone
