摘要
应用五点剩余曲线法对玉溪深井高精度地温日均值进行分析,在异常结束后两个月内对应300km内M≥5.0和600km内M≥6.7地震,且异常幅度与震级有较好的线性相关,显示出明显的临震前兆特征。
In this paper, daily average values of geotemperature measured in high precisiondeep bore-hole in Yuxi area are analysed using 5 point residual curve method. The studyshows that uss. 0 earthquakes with in 300 km range and M≥6. 7 within 600 km rangewill probably occur within 2 months after anomalies appear. Furthermore, the anomalousamplitudes and the magnitudes have good linear correlation, which demonstrates clearearthquake precursory features.
