| 摘 要： | 1998年1月5日发生的泾阳Ms4.8级地震是陕西省近40年来发生的最大一次地震。对这次地震的构造背景和震前的各种异常现象进行了研究，发现震前该区地壳形变、地下流体和地震活动表现出长期、中期和短期的不同特征。对此次地震的构造背景作了分析，并根据岩石破裂实验和地震前兆理论对这次地震的孕育过程作了阶段性划分。

| Abstract: | The Jingyang earthquake which occurred on January 5,1998 is the greatest one in recent forty years in Shaanxi Province. By studying the tectonic background and various pre earthquake anomalous phenomena, the authors thought that before the earthquake the crustal deformation, underground fluid and seismicity in this region exhibited different characteristics in long, middle and short term. They divided the preparation process of this earthquake into several stages according to the tectonic background analysis, the results of rock fracture experiments and the theory of seismic precursors. |
