山西地区地震形变观测调研

Research on the observation of earthquake deformation in Shanxi region

形变观测是地球物理观测的重要手段之一,以能够清楚地观测地球固体潮汐为发展目标,对地震监测预报具有重要作用。为进一步加强山西省地震监测及预测预报工作,全面了解和掌握1985年以来山西省形变观测资料的变化,探讨形变台网观测资料在监测预报中发挥的重要作用,系统梳理山西地区形变观测资料变化,对山西省历史及目前运行的形变学科仪器、数量等进行全面摸排,为该区形变观测工作提供参考。结果表明,山西形变观测已有一定规模,并具有以下特征:(1)观测仪器设备种类多,监测手段全,但仪器标准化程度不高;(2)观测资料具有一定的映震能力;(3)观测环境较复杂,应进一步做好观测环境保护。

Deformation observation is one of the important means of geophysical observation,with the development goal of clearly observing the Earth’s solid tides,playing an important role in earthquake monitoring and prediction.In order to further strengthen earthquake monitoring and prediction work in Shanxi Province,comprehensively understand and grasp the changes in deformation observation data in Shanxi Province since 1985,and discuss the important role of deformation network observation data in monitoring and prediction,this paper systematically summarizes the changes in deformation observation data and makes a comprehensive survey of the historical and current operating deformation instruments and quantities in Shanxi Province,providing a reference for deformation observation work in this area.The results indicate that deformation observation in Shanxi Province has reached a certain scale and has the following characteristics:①There are many types of observation instruments and equipment,with complete monitoring methods,but the standardization level of instruments is not high;②The observation data has a certain ability to reflect earthquakes;③The observation environment is relatively complex,and the observation environment should be further protected.
