【摘要】 通过对丽江井数字化地下水温观测资料进行的初步研究,发现该井在川滇地区发生的多次中强以上地震前有短临异常,异常形态可分为三类:第一类是日潮差变化和温度阶升;第二类是震前水温出现大幅降温;第三类为震前出现水温固体潮汐形态畸变和多次温度突跳。丽江井数字化水温震前的短临异常特征对做好未来地震的短临跟踪及地震预测有着实际应用价值。更多还原

【Abstract】 Based on researches into the Bore-hole Water Temperature Anomalies in Lijiang seismic station,it is argued that some short-term anomalies can be observed before medium-strong earthquakes located in Sichuan-Yunnan region.These anomalies can be summarized as three types: 1) diurnal range changes and temperature going up;2) the water temperature decreases before earthquake;3) the shape distortion of earth tide and step of the water temperature before earthquake.The short-impending anomaly characteristics of the water temperature in Lijiang Well is significantly important for future earthquake short-term track and earthquake prediction.更多还原
