摘要: 1996年包头西6.4级地震是一次十分重要的地震,又是一个非常特殊的地震。集二十多年对强震前主要震兆特征和地震活动图像演化的认识,无论在6.4级地震前看到的,还是震后震例总结的,种种震兆异常基本集中在临河地区,而不是包头地区。作者从7个方面阐述了包头西6.4级地震的震兆特征的特殊性,提出这类地震如何预报问题。

Abstract: The Ms 6.4 earthquake occurred in west Baotou on May 3, 1996, is a very specific strong earthquake. With the know ledge of seismic precursor characteristics and earthquake pattern evolution before strong earthquakes for more than 20 years, the Ms 6.4 is different from other strong earthquakes in Yinshan belt. The anomalies before and after the Ms 6.4 quake were found in Linhe rather than in Baotou. We discussed the specific characteristics of seismic precursors before the Ms 6.4 earthquake from seven respects, and proposed a suggestion of prediction for this kind of strong earthquakes.

Key words: Seismic precursor characteristics, Earthquake prediction, Western Baotou earthquake
