摘要
在日常地磁观测数据处理过程中,经常会遇到观测数据记录曲线异常现象,这些异常现象,有的是地震信息异常,有的则是由于各种干扰引起的,因此,在数据处理过程中,正确区分和准确识别地磁观测数据中异常与干扰、造成干扰的原因以及对干扰数据的处理,是在观测数据预处理中所应具备的能力,同时也能够为地震监测与预报提供真实准确的信息支持。
Abnormal phenomena of observed data recording curve usually appear in the process of dealing with the data of geomagnetic observation. Some of these phenomena are abnormity of seismic information; some are caused by various interference. Therefore, accurately distinguishing and identifying abnormity and interference, is necessary in pretreatment of observational data, which meanwhile provides the monitoring and forecasting of the earthquake with accurate information in the course of data processing.
