Tracking analysis of typical events in the site environment of Hebei geophysical station network

Abstract

In this paper，the typical site environmental events covered by 48 stations in 7 center stations of Hebei geophysical station network are reviewed, involving deformation, geoelectricity, geomagnetic and fluid disciplines. According to the number of recorded events and the number of affecting instrument sets, typical influential factors such as HVDC transmission, equipment leakage, water (oil) well spring pumping, and reservoir water level fluctuation are selected for analysis. The process of occurrence of the event is described in detail, its rules and reasons are found, and effective solutions are proposed to provide reference for anomaly verification, analysis and prediction.
