摘要
地震前兆台网观测数据跟踪分析是地震预报的重要基础,对观测数据干扰进行分析排除是提取地震前兆信息的核心。通过对张道口地震台2015~2018年水物理观测数据受干扰情况分析,及时发现和总结观测数据存在的各种问题,将干扰分为人为干扰、系统干扰、自然干扰、场地环境4种类型,并将6种具体干扰分别归纳到了相应的干扰类型,找出了干扰的特征,描述了干扰的过程,分析了引起干扰的具体原因,阐释了干扰对水温水位前兆数据观测造成的影响,并对干扰的过程进行了相关的验证,提出了避免干扰的技术措施。通过对水位水温干扰全方位的分析研究,能够促进对地震前兆信息的处理,以期快速准确地识别并排除前兆干扰,为全国其它地震台水位水温干扰分析提供一定的科学依据和技术支持,夯实通过水物理测项预报地震的基础。
Tracking and analysis of observed data is an important basis of earthquake prediction,and analysis and elimination of observed data interference is the core of extracting earthquake precursor information.Analysis of disturbance to hydrophysical observation data at Zhangdaokou seismic station from 2015 to 2018,timely find and summarize the problems existing in the observation data.The interference is divided into human interference,system interference,natural interference and other aspects,and the corresponding interference types of 6 specific interference are summarized respectively.The characteristics of interference are found out,the process of interference is described,the specific causes of interference are analyzed,the influence of interference on water temperature and water level precursor data observation is explained,the process of interference is verified,and the technical measures to avoid interference are put forward.Through comprehensive analysis and study of water level and temperature disturbance,it can promote the processing of earthquake precursor information,so as to identify and eliminate precursor disturbance quickly and accurately.It provides scientific basis and technical support for water level and temperature interference analysis of other seismic stations in China,the foundation of earthquake prediction through water physical measurement is compacted.
