山西地震预警系统数据处理结果浅析

Analysis of Data Processing Results of Shanxi Earthquake Early Warning System

山西地震预警台网2022年成功处理并产出了多次地震预警信息。从台网布局、预警处理产出及右玉Ms4.0级预警处理结果来浅析山西地震预警能力。结果表明,山西地震预警网使用的两套地震预警系统产出的预警结果发震时刻、震中位置总体稳定可靠,但震级整体偏大。对3种类型台站的震级偏差进行分析,发现一般站震级偏差最大,其次是基本站和基准站。总体来看,山西地震预警系统台网运行基本正常,具备一定的地震预警能力。

Shanxi Earthquake Early Warning Network successfully processed and produced many earthquake early warning information in 2022. Analyzes the earthquake early warning capability of Shanxi Province from the network layout, early warning processing output and Youyu Ms4.0 early warning processing results. The results show that the early warning results of the two sets of earthquake early warning systems used by the Shanxi Earthquake Early Warning Network are generally stable and reliable, but the overall magnitude is relatively large. After analyzing the magnitude deviation of three types of stations, it is found that the magnitude deviation of general stations is the largest, followed by basic stations and reference stations. In general, the network of Shanxi Earthquake Early Warning System is basically operating normally and has certain earthquake early warning capability.
