【摘要】 介绍了青海地区水温(地温)的观测概况。经过研究,发现大柴旦M6.3地震前,距离震中160 km的格尔木自流井水温出现了短期异常,距离震中130 km和600 km的德令哈静水井水温和同仁井地温出现了准同步短临异常变化。除开始阶段外,同仁井地温与德令哈井水温在异常形态上基本相反,而格尔木井和德令哈井的异常形态均表现为下降—上升—平稳—下降—恢复的特征。说明地温与水温异常形态存在差异。更多还原

【Abstract】 This article introduced the general situation of water temperature observation in Qinghai province,analyzed the observation data.Our study shows that before the Dachaidan M6.3 earthquake in 2008,short-impending anomaly appears in Golmud artesian well 160 km away from the epicentral area,meanwhile,the Dlingha still water well and the Tongren ground temperature,130 km and 600 km away from the epicentral area,also show quasi synchronization short-impending changes. The form of the anomalies in the Tongren ground temperature and the Dlingha still water well are basic opposite except the beginning part,while the anomalies in the golmud well and delingha well are in the similar form of descending-ascending-stable-descending-recovering,which may indicate that there are differences between ground temperature anomaly water temperature anomaly.更多还原
