Monitoring,Early Warning,and Intensity Rapid Reporting Capabilities of Hunan Earthquake Earky Warning Station Network
摘要
Abstract
As of the end of 2023,the comprehensive construction of the Hunan early warning station network system has been completed.In this paper,the maximum probabilistic peak ground displacement(PGD)was used as an index to calculate the background noise level of three types of stations in Hunan.On this basis,the traditional earthquake monitoring capability evaluation method,the four-station positioning theory considering timeliness,and the average station spacing method were used to comprehensively analyze the theoretical monitoring,early warning,and intensity rapid reporting capabilities of the Hunan early warning station network system.The results show that 95%of areas in Hunan Province can monitor earthquakes below ML2.1,with a warning time of less than 10.1 seconds,and warn earthquakes above ML4.4,with an accuracy of intensity rapid reporting below 38 km.After the completion of the Hunan sub-project of the National Earthquake Intensity Rapid Reporting and Early Warning Project,the Hunan Early Warning Station Network has a certain level of early warning and intensity rapid reporting capabilities,and has good earthquake monitoring capabilities.关键词
