Abstract: The article evaluates the continuous operation rate, station noise level, event waveform quality, and warning information release effect of the Jiangsu early warning station network system, and calculates the monitoring capacity of the Jiangsu early warning network.Believing that the Jiangsu earthquake early warning network system operates stably, with good data recording quality.Provincial monitoring capacity can reach M_L 1.0 in local areas and M_L 1.5 in most areas.The Jiangsu Early Warning Network has preliminarily acquired the ability to quickly report earthquake intensity and regional earthquake early warning in the province.
