摘要
系统分析康定龙头沟温泉逸出气CO_2的百分含量异常与该区域中强地震的对应关系。发现龙头沟温泉CO_2的百分含量成组异常(3个月时间内出现多次突降,N≥2次),在该区域中强地震的中短期预报中比单次异常更为可靠,可以在日常地震分析预报中加以运用。
In this paper, through a systematic analysis of the relativity between percentage content anomaly of the escaping CO2 from the hot spring at Kangding Longtougou and the moderate strong earthquake in the region, it is found that the group anomalies of CO2 percentage content of hot sprint in Longtuogou （within three months if there is multiple dump, N≥2 times） is more reliable than a single anomaly for the short-term forecasting of strong earthquake in the region. This result can be applied in the routine earthquake analysis and prediction.
