摘要
1975-2005年间,四川省理塘毛垭温泉水温变化与地震有一定的对应.地热变化异常与地震的密切关系已被较多震例所证实. 2005年2月25日(温泉水温53 ℃)～3月14日(温泉水温26.9 ℃),毛垭温泉水温下降了26.1 ℃,2月水温月均值54.1 ℃、3月水温月均值30.7 ℃,下降了23.4 ℃,这一现象引起了地震系统各级领导和专家的高度重视.2005年3月中国地震局监测预报司在成都主持召开了南北地震带紧急震情会商会.根据会议决定,四川省地震局预报研究所组织了'毛垭温泉水温异常专题研讨会',针对毛垭温泉水温下降异常,将30年来的资料进行了系统全面的分析,对于毛垭温泉的地震地质背景、温泉的热源、水温异常与强地震的关系作了较深入的研究,并且重点研究了水温下降异常特征与川滇两省强震的关系,对于毛垭温泉未来水温的三种动态变化趋势和近期川滇两省的强震趋势进行了探讨.
For the last 30 years, we find that some of the temperature changes of spring water in Maoya, Litang County, are relative to some of earthquakes there. From 25 February 2005 to 14 March 2005, the spring water temperature changes from 26.9 E to 53 E. The abnormal changes made us feel anxious about the seismic tendency in this ares. The seismic geology condition, the hot sources of spring, the relationship between the abnormal changes of spring water temperature and the earthquakes are discussed in this paper. The key topic is the relationship between the dynamic changes of spring water temperature and the earthquakes in both Yunnan and Sichuan Provinces.
