Discussion on Location Selection of Broadband Seismic Monitoring Stations in Yunnan Field of China Earthquake Science Experimental Field Construction Project——Taking Wenshan and Qujing Areas as Example
The selection of seismic monitoring stations is crucial for ensuring high-quality seismic observation data,functional integ-rity,and stable operation of the stations.This process demands advanced technology,substantial experience,and lacks specific working methodologies.In response to the requirements of the China Earthquake Science Experimental Field Construction Project in Yunnan province,focused on broadband seismic monitoring,a survey and selection of 24 intention stations in Wenshan and Qujing areas of Yunnan province was conducted.This paper outlines the key stages involved in the survey and selection of intention stations for broad-band seismic monitoring,organized into five stages:indoor data collection,station site mapping,field survey to determine the intention station site,negotiations and signing of land lease agreements,and indoor data sorting and selection.Site mapping plays a pivotal role in the field survey and determination of intention station sites,significantly enhancing survey efficiency.Using the survey and selection of the CD151 intention station as an example,this paper discusses in detail the methodologies employed across these five stages.The feas-ibility of this approach is validated through noise level tests and analysis conducted at four intention stations.These selected stations ex-hibit noise levels consistent with Grade Ⅰ station standards,meeting the technical requirements for observation environments based on Grade Ⅲ station ground noise surveys.This study provides valuable reference and practical insights for the selection of broadband seis-mic monitoring stations,emphasizing the importance of systematic survey methodologies to ensure effective station deployment and op-erational success.
