宏观前兆是目前地震短临预报的重要指标之一。几次地震前鲜水河断裂一带宏观异常现象比较明显。本文就近三十年来鲜水河断裂带,破坏性较大的四次强震,某些宏观前兆特征进行分析总结,就其可能的共同原因进行粗浅的讨论,以期对本区地震短临预报有所裨益。 Macroeconomic precursors are one of the important indicators of short-term and short-term earthquake prediction. A few macro-anomalies were observed in Xianshuihe fault zone before the earthquake. In this paper, the recent 30 years, the Xianshuihe fault zone, the more destructive four strong earthquakes, some of the macroeconomic precursors to analyze and summarize their possible common causes of superficial discussion in order to short-term earthquake prediction in this area benefit.
