摘要
云南省地震频发,形变观测短临数据跟踪对地震工作具有较明显的指示意义。降雨干扰对形变观测多为缓慢变化影响,这些变化隐藏在众多地震前兆异常中,影响地震观测数据的使用。本文通过对昆明地震台历年降雨及形变观测数据的分析,总结降雨干扰规律,以便准确提取并有效识别地震前兆异常。
Yunnan Province is always prone to earthquake. The deformation observation has obvious indicative significance in impending earthquake tracking analysis. Rainfall interference is mostly slow influence on deformation data. The influence hides in numerous precursory anomalies and interferes the usage of observation data. We analyzed the rainfall and deformation observational data of many years, and summed up the law of rainfall interference, in order to accurately extract and effectively identify earthquake precursors.
