| 摘 要： | 从乌鲁木齐10号泉观测点的地质构造背景以及甲烷的物理化学性质等方面入手,分析了该泉21年来甲烷测项所出现的3次长趋势异常变化的原因,初步认为主要是对远场大地震的。应力一应变事件”的响应,同时也包含了乌鲁木齐周围地区(300km范围)中等强度地震的一些地震前兆信息。

ANALYSIS ON THREE LONG-TERM TRENDING ANOMALIES OF METHANE IN URUMQI NO.10 SPRING |
| |
| Abstract: | During 1982-2003, three long-term trending methane anomalies appeared in Urumqi No.10 Spring. From the geological tectonic environment around the spring and the physical-chemical character of methane, cause of the anomalies was analyzed. It is preliminarily thought that the anomalies was the respondence for far-field earthquakes, meanwhile, they also contained some precursor informations of mediun-strong earthquakes in the area of 300 km around Urumqi. |
