依据以场求源,中、短、临逐步逼近的科学思路,在总结了华北地区6级以上地震的基础上,提出了进行短临预报必须具备的背景依据,前兆异常指标和地震三要素的判定方法。
In this paper,in terms of a scientific train of thought of obtaining a source with a field and gradually approximating mid-term to short-term, and based on the summary of the earthquakes of M≥6 in North China area, we have proposed the background basis, precursory anomaly index and the judgment method of earthquake three elements which are necessory for short-term and imminent earthquake prediction.
