| 摘 要： | 研究分析了 1 998年 1月 5日陕西泾阳MS4.8地震前高陵测点 1 0m地温的变化特征 .1 997年高陵地温呈下降变化 ,1 2月 1 5日地温突升 .该次地震前 1 5天地温升高现象非常明显 ,震后恢复正常 .西安市高压开关厂测点 1 0m地温也从 1 997年 1 2月中旬开始出现上升异常 ,1 998年 1月 1日地温上升速率突然加大 .可以认为 ,高陵测点观测到的 1 0m地温异常是可信的 .

| Abstract: | Variation features of geotemperature in the depth of 10 m by Gaoling observation point before the Jingyang M S4.8 earthquake on Jan.5,1998,Shaanxi province are studied and analyzed.The geotemperature fell continually in 1997.The geotemperature rose suddenly from Dec.15,1997,especially in 15 days before the event and returned to normal after the event.Geotemperature variation in the depth of 10 m by observation point of high pressure switchgear plant of Xi'an city is the same as that by the Gaoling point.It is believed that rising variation of the geotemperature by the Gaoling point is the anomaly before the Jingyang M S4.8 earthquake. |
