广东地震预警系统产出结果分析OACSTPCD

In order to improve the earthquake early warning business in Guangdong Province and enhance the disaster reduction efficiency of the earthquake early warning system,the early warning results of the earthquakes with M≥3.0 in 2023 were analyzed in terms of early warning time,epicenter location deviation,and magnitude deviation.The results show that the early warning results of the Guangdong Earthquake Early Warning Network are processed relatively quickly and meet the timeliness requirements.On the whole,the epicenter location and magnitude deviation of the early warning results from the Guangdong Earthquake Early Warning Network are relatively small,and the accuracy is satisfactory.On the basis of the above analysis,the early warning result analysis work flow is carefully sorted out,which enables the relevant personnel to analyze early warning results in a comprehensive,orderly,and efficient manner.
