康定温泉逸出气短期预测研究

康定温泉逸出气气体百分含量的观测始于1986年,期间先后经历了多次甘孜州及邻区5.0级以上地震。地震前康定温泉逸出气观测资料均有不同程度的短临异常。本文在系统整理和深入剖析两泉点自有观测以来的在甘孜州及邻区发生的5.0级以上地震震例资料的基础上,借助多次“攻关”成果,排除观测资料的各种干扰因素及仪器标定变更情况,总结各观测资料短临异常特征、中短期异常特征及中短期异常特征随时间变化规律,提出康定温泉逸出气短临异常指标。

Short-term prediction study fron the data changes of the gas escaped from hot spring water in Kangding Seismic Statin

The percent content observation of the gas escaped from the hot spring water begins in 1986.During this periob,there are a lot of about M5.0 earthquakes in the region of Ganzi Tibet Autonomous Prefecture in Sichuan Puovince.Before the earthquake,the observation data of the escaped gas show some of prcursor changes.According to the earthquake cases summarized from 1986 for about M5.0 earthquakes in Ganzi region and the statistical relationships between the changes of the precursor data and the earthquakes in the region of Ganzi Tibet Autonomous Prefecture in Sichuan Province,we exclude the possibility of the instrument interfering and other factore.Then we summarize their relative characteristics among the several kinds of data,the short-impend precursors and the medium-to-short-term precursors with the time.Based on the precursor observation data of the percent content escaped from hot spring water in Seismic Station of Kangding,we put forward the short-impending index.
