- Abstract:
- Based on the observation data of Hydrochemistry in Yunnan Province from 2000 to 2017,a traditional analysis method of identifying anomalies with original observation curve is used to extract single and group anomalies and analyzed the relationship between them and earthquakes.The results show that during the research period,the utilization rate of hydrochemical data in Yunnan is 56%,which reflects the uneven seismic reflection capacity of hydrochemical observation stations.The earthquake case study shows that the hydrochemical anomalies are mainly short-term anomalies,accounting for 70% of the total anomalies.The prediction efficiency of the earthquake is good,and 76% of the items are not false.The single station group and regional group anomalies are closely related to earthquakes.The number of anomalies in the area with dense stations is large and the earthquake response rate is high.The construction of high-density and high-quality observation points is an important basis for improving the earthquake prediction ability of hydrochemical data.
