Analysis of Jiangsu Earthquake Early Warning Information Service System
This article introduces the Jiangsu Earthquake Early Warning Information Service System,part of the National Earthquake Intensity Rapid Reporting and Early Warning System,and analyzes its performance since the system's trial operation began in June 2023.The results indicated that the pri-mary delay in releasing early warning information occurred between the earthquake event and the offi-cial release of early warning information by the national level integrated decision-making system.The shortest delay observed was 4 seconds,with an average delay of 14.3586 seconds.The Jiangsu Earth-quake Early Warning Information Release System exhibited minimal delays at various stages of infor-mation release,with an average total delay of less than 0.9 seconds.In the event of an earthquake at a Type Ⅱ provincial early warning center,the release delay would be slightly longer compared to a Type Ⅰ center.Overall,the Jiangsu Earthquake Early Warning Information Service System meets timeliness requirements and demonstrates good stability.Upon completion of the provincial early warning project,it will enable second-level destructive earthquake early warning information release and demonstration services within the province.
