摘　　要：对云南省通海地震台垂直摆倾斜仪观测资料在2014年云南盈江MS6.1、鲁甸MS6.5、景谷MS6.6地震前出现的异常进行了分析,结果表明,通海台倾斜仪在震前出现明显的中期、短临异常,有明显的趋势转折、破年变、矢量反向、速率超2倍均方差等现象。The data recorded by vertical pendulum tiltmeter located in Tonghai station before the Yingjiang Ms6.1, Ludian Ms6.5, Jinggu Ms6.6 earthquakes in Yunnan were analyzed. Results show that some differences like short-term anomalies, medium-term anomalies have turned out, including breaking year change, direction changing, vector steering and degree of variation exceed twice of the mean variance.
