摘　　要：20 0 1年 1月 9日起开始宁波台矿泉井井水温度出现异常 ,通过检查、分析后认为很可能与萨尔瓦多 8 0级地震有关系。从日均值图上看 ,异常在震前 6天开始出现 ,至震前 1天达到最大 ,表现为打破正常的波动规律 ,呈负异常 ;从整点测值图看 ,主要是震前 36小时出现负阶跃。分析认为出现的水温异常可能是一种地震前的长周期波通过上地幔或软流层传播而至 。The water temperature in mineral water well of Lingbo Seismographic Station had changed abnormally since January 9,2001,this change was thought relative to the Salvado earthquake with M S8 0 in some extent after analyses.According to the daily mean map,the anomaly began six days before the earthquake and went up to the maximum one day ago,the change was over the usual limit and presented negative anomaly.According to the measurement values at the integral points,the anomaly began 36 hours before the earthquake and it was negative too.The anomaly was considered as the subsurface fluid temperature change caused by a long period wave propagating through upper mantle or asthenosphere before an earthquake.
