| 摘 要： | 华山山前断裂带晚第四纪以来具有明显的新活动,沿断裂带及其两侧分布有最新断层崖,基岩裂缝、黄土裂缝、山体崩(滑)塌体等众多的地震形变和破坏遗迹,华山山前断裂带应是1556年华县8级地震的发震断层。 从本文提供的一个古地震剖面分析,华山山前断裂带全新世以来可能发生过四次大地震,其重复间隔约2000—2500年

| Abstract: | Since the late Quaternary Period, there have been conspicuous neotectonic activities on the frontal fault zone of the Huashan mts. The strong deformation damage relics due to earthqnake, such as new fault scarps, base rock fractures, loess crevices, and land slides are distributed along the fault zone and nearby. The frontal fault zone must be the genetic fault of the 1556 Huashan earthquake (M = 8).Based on the analysis of a palaeoseismic profile, it is supposed that four great earthquakes have probably occurred since the Holocene Epoch, the recurrence interval being about 2000-2500 years. |
