肃南地震台形变观测资料干扰识别与排除
A research on interference recognition and fault resolution for deformation observations in Sunan Seismic Station
【摘要】 收集整理甘肃省地震局肃南地震台形变数字化观测资料,对降雨、大风、人员进出、仪器调零、断电或者电压不稳定,以及其他仪器故障等因素造成的干扰进行分析;为数字化资料的利用、各种干扰的识别以及捕捉地震短临异常,提供可借鉴的实例。
【Abstract】 Based on the digital deformation observations collected and processed in Sunan Seismic Station,Earthquake Administration of Gansu Province,we analyzed and investigated the interference attributed to rainfall,strong wind,artificial factor,instrumental zero alignment, power-off,voltage instability and other equipment failures.Some instances are given as well,which can be used as a reference for utilizing digital data to recognize various kinds of interferences and catch the short-term and impending anomaly.
