榆树地电阻率台观测效能评价
|
摘要
本文根据中国地震局电磁学科制定的《地电台站观测效能评估方案》,评估了榆树地震台地电阻率观测效能。评估结果如下:榆树台台址结构条件、电磁环境、台站观测系统符合地电阻率台站建设规范、观测方法标准等规定的技术要求;数字化地电阻率观测精度不低于3‰测值,保证了准确测量不低于1%地电阻率异常的指标需求;该台地电阻率观测对本区及附近中等以上地震有一定监测能力,并记录了对应深源地震及邻区中强地震的1年尺度地电阻率异常,其观测数据在本区及附近地震监测、预报和地震科学研究及相关科学研究中有重要价值。
According to the"Broadcasting station Observation Efficiency Appraisal Plan"established by China Earthquake Administration authority electromagnetism discipline formulation,the observation efficiency of terrace electronic resistivity observation system in Yushu Seismic Station is estimated.The results show that the site structure condition,the electromagnetic environment and the station observation system in Yushu conform to earth resistivity station stipulation and so on construction standard and standard prescriptive technical specifications about observation method;The digitized earth resistivity observation precision is not lower than 3‰ of measures,which guarantees to satisfy the target demand that the correct measurement is not lower than 1% earth resistivity unusua1.The electronic resistivity observation at this station has the capacity to monitor the middle earthquakes in local and nearby region,and record the 1 year criterion earth—resistivity anomaly of deep quakes.Its observation data are high valuable for the earthquake monitor and prediction in the local and nearby region and for the research in other discipline.
