Analysis of Instrumental Intensity Output of the Jiangsu Subsystem in the National Earthquake Intensity Rapid Reporting System
This paper presents an analysis of the Jiangsu subsystem within the National Earthquake In-tensity Rapid Reporting and Early Warning System.It provides an overview of the system's perfor-mance since its implementation in December 2021.The study focuses on the most significant seismic event recorded since deployment-the M4.2 earthquake in Tianning,Jiangsu on December 22,2021.Using the f-k method,theoretical seismograms were synthesized for various observation stations.By comparing actual peak accelerations with the theoretical values,the reliability of the Jiangsu subsys-tem's performance was assessed.The results indicate that the peak ground accelerations produced by the rapid reporting system decreased with increasing distance from the epicenter and were relatively consistent with the theoretical seismograms,thus demonstrating the reliability of the Jiangsu subsys-tem's output to a certain extent.
