On 1932 December 25, a destructive earthquake of magnitude 7.6 occurred in the region of Changma, Kansu corridor. In the meizoseismal area, there appeared a large number of fissures and fractures, consisting of types of tension, compression and shear. In this paper, the authors analyse the forms and conditions of producing different kinds of fractures associated with the characteristics of regional tectonics, and then, propose a tentative pattern of field stress related to the seismogenesis for the present earthquake.This seismic event was principally due to the nearly north-south horizontal com-pressional force, which had long been dominating this region since the time of Cretaceous. The new seismic fractural zones appeared nearly coincided with the active area of Changma tectonic faulting. Therefore, it may be concluded that the present earthquake was an episode in the long term of Changma faulting movement.

1932年12月25日,我国甘肃省西部玉门镇以南的昌马地区发生了7.6级地震。震中区产生了规模较大的地面破裂带,其中有张性、压性和剪切等多种型式裂缝。本文根据分析各种自然破坏现象的形成条件,结合极震区地质构造特征,对震源区的应力作用和地震成因提出初步看法。 对地震破裂带的分析结果表明,这次地震起主要作用的是南北向的水平挤压作用,并与自白垩纪以来控制着本区构造断裂的区域应力场是一致的。地震破裂带出现的部位与长期活动的昌马构造断裂带一致。因此,我们认为昌马地震的发生是昌马构造断裂带继承性活动的结果。

The similarity in the seismogenic structure, rupture mode and the focal stress field indicates that the earthquake of magnitude 6.0 occurred in Haicheng on May, 18, 1978 can be regarded as a strong aftershock of the 1975 Haicheng earthquake with magnitude 7.3. After main earthquake there have not been intensive activities of aftershocks. But they toke place much later, it may be explained by the disrupture of the locked section of NNE running active structure.The authors of this paper re,fer the strong shocks...

The similarity in the seismogenic structure, rupture mode and the focal stress field indicates that the earthquake of magnitude 6.0 occurred in Haicheng on May, 18, 1978 can be regarded as a strong aftershock of the 1975 Haicheng earthquake with magnitude 7.3. After main earthquake there have not been intensive activities of aftershocks. But they toke place much later, it may be explained by the disrupture of the locked section of NNE running active structure.The authors of this paper re,fer the strong shocks taken place within 10 years after the main shock to be the late strong aftershocks. By the synthetic analysis of the geotectonic features and the nature of the whole seismic activity series of the Haicheng earthquake, it is shown that the multi-locking structures must be a necessary background and the locations for generating the late strong aftershocks. Its anomalous precursory, however, was less obvious and appeared only along the direction obliquely aerossing the principal structure in area concerned. Some characteristics of the late strong aftershocks and relevant strike-slip mechanism are slao discussed herein.

本文从震源区、发震构造和破裂方式等的相似性,认为1978年5月18日海城6.0级地震是1975年7.3级地震的晚期强余震活动。结合震区地质构造的分析,提出晚期强余震的发生是与残余闭锁区的崩解相联系。因而,主震后,震源区残余的闭锁结构处正是尔后晚期强余震的所在位置。文中还对这种残余闭锁区的形式及其与粘滑机制的关系作了分析。
