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 CO_2 from the hot spring at Kangding Longtougou and the moderate strong earthquake in the region,it is found that the group anomalies of CO_2 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.
