作为国家地震台网和区域地震台网的重要补充,地市级地震台网可为本地区地震速报、地震预警、城市防灾减灾和活断层科学研究提供基础数据。本研究采用基于NetSeis/IP协议的网络组网技术,将单个测震台站组建成台网,形成由16个子台组成的地市级地震台网。应用专业软件对组网前后地震监测能力进行评估,结果显示,包头主城区及周边部分地区地震监测能力有了明显提升,达到ML 1.0。同时,以包头主城区及周边地区为研究区域,选取包头地震台网运行以来的地震目录进行检验,证实研究区地震监测能力优于ML 1.0。
As an important supplement to the national and regional seismic networks, the prefecture-level seismic network can provide basic data for regional earthquake rapid report, earthquake prediction, urban disaster prevention and reduction, and scientific research on active faults. This study adopts a networking technology based on the NetSeis/IP protocol to set up a seismic network by assembling individual seismic stations, forming a prefecture-level seismic network composed of 16 substations. The application of professional software to evaluate the seismic monitoring capability before and after networking shows that the seismic monitoring capability in the main urban area and surrounding areas has significantly improved, reaching ML 1.0. At the same time, taking the main urban area and surrounding areas of Baotou into research, the earthquake catalogue of the Baotou Seismic Network since its operation was selected for further testing, confirming that the seismic monitoring capacity of the research area is better than ML 1.0.
