逸出气体的监测及其与地震活动的关系

PRELIMINARY RESEARCH ONTHE RELATION BETWEEN THE OBSERVATION OFESCAPING GAS FROM GROUNDWATER AND EARTHQUAKE ACTIVITY

地下流体能较好地反映地壳应力的变化,对地震前兆的监测预报有一定的意义。本文通过对地下热矿水中逸出气的组分、总量及其与溶解气量比的观测和试验,表明地下水中的逸出气体有良好的震兆作用,其中逸气总量以及逸出氦等组分可望成为映震的灵敏测项,有必要深入开展观测研究。本文还介绍了自行设计的集气装置及效果较好的现场简易测量方法。

By studying the gas compositions and the total quantity of the escaping gas from hot groundwater and their ratio compared with the puantity of dissolve gas, we find that escaping gas from groundwater is significant to indicate earthquake precursor. The two items, the total quantity of escaping gas and the quantity of escaping Helium, are considered to be sensitive factors for indicating earthquake precursor. This paper also introduces a instrument designed by the author for collecting gas and a easy method for site measuring the total quantity of escaping gas.
