对赤峰地区痕量氢观测点选址建设的思考

Consideration on Site Selection and Construction of Trace Hydrogen Observation Station in Chifeng Area

近年来,痕量氢观测技术在地震监测预报中的应用较为广泛,特别是在地震短临预报中效果更为明显。在山西、云南、新疆等地开展的地震短临预报中痕量氢观测均发挥了重要作用。2018年赤峰地区也相继建立了三个痕量氢观测点。通过近三年时间对观测点的日常维护和数据分析处理,发现痕量氢观测点在选址建设时存在一些问题,如果避开这些问题,痕量氢观测数据受到的干扰可能会较小,震前短临异常效果会更明显。

In recent years,trace hydrogen observation technology has been widely used in earthquake monitoring and prediction,especially in short-term and prediction.After learning from the important role of trace hydrogen observation data in short-term prediction in Shanxi,Yunnan and Xinjiang,three trace hydrogen observation stations have been established in Chifeng in 2018.Through the daily maintenance and data analysis of the observation points for more than three years,it is found that there are some problems in the site selection and construction of the trace hydrogen observation stations.If these problems can be avoided,the trace hydrogen observation data may be less disturbed,and the short-impending anomaly effect before the earthquake will be more obvious.
