摘要
分析合肥地震台电磁扰动观测资料的干扰因素及其特征,发现台站地电阻率供电和大功率用电器的使用对DC-Ⅱ型电磁扰动仪影响显著,在一些地震发生后,电磁扰动数据出现不同程度变化,且变化形式各有不同。
Analyzing on the interference factors and their characteristics of the electromagnetic disturbance observation data of Hefei Seismic Station, we found the usage of the earth resistivity and the high power electric appliance has the obvious effect on the DC-Ⅱ type electromagnetic disturbance. The electromagnetic disturbance data appear different degree of change after some earthquake, and there are different forms of these types of changes.
