This paper deals mainly with the geotectonic background of the seismicity in the Tancheng-Lujiang fault zone, with emphasis on the relationship of Late Quaternary active faults in southern part of its middle segment to the earthquakes. The seismicity is clearly different in various segments, this is well correlated to the difference of geotectonic units with various characteristics and faulting activities in the Late Quaternary.The evidences on the intermittent motion (stick-slip motion) of the active faults...

This paper deals mainly with the geotectonic background of the seismicity in the Tancheng-Lujiang fault zone, with emphasis on the relationship of Late Quaternary active faults in southern part of its middle segment to the earthquakes. The seismicity is clearly different in various segments, this is well correlated to the difference of geotectonic units with various characteristics and faulting activities in the Late Quaternary.The evidences on the intermittent motion (stick-slip motion) of the active faults found in the southern part of the middle segment can be regarded as a geological indicator to discriminate the paleo-earthquakes and to estimate roughly their recurrence. It is clear that this indicator is of practical significance for evaluating the seismic tendency of the active fault zone. In the meantime, by the geological and seismological analogues the authors propose that in the same tectonically active zone where occurred strong historic or prehistoric earthquakes, exists a possibility of recurrence of earthquakes in the same location. However, it is to be noted that some segments of this zone, where the tectonic conditions are similar in occurrence of earthquakes and evidences of intermittent motion of active faults since Late Pleistocene are found and where seismic gaps last more than two thousands years, can be referred to the temporal "quiet segment". The earthquake risks in these segments may actually be rather serious than that in the segments with recent activities. Therefore, we had better not say the former segments to be more safe in the near future. It has already been verified by the fact that in the recent /ears quite a few strong earthquakes took place in the historical seismic gaps being tectonic-ally newly-reactivated. In conclusion, to make the seismic zonation more exact it should pay attention to the investigation of the geologico-geomorphological evidences on recurrence of large earthquakes in the active fault zone within plates.

本文概述郯城-庐江断裂带地震活动的地质构造背景和第四纪晚期断层新活动与地震的关系。指出沿带地震活动性具有明显的分段性,这与各段位于不同性质的大地构造单元和第四纪晚期断裂活动的差异性有较好的相关性。活断层粘滑运动的遗迹,是鉴别古地震及其重复发生的一种地质标志。同一活动构造带,强震有原地重演的可能。晚更新世以来发生过断层的粘滑运动,而二千多年来又无强震的“地震休眠段”,其危险性将比历史地震区(段)更紧迫。必须考查板内活断裂带强震重复活动的地质-地貌标志和年代学的研究。

According to the latest observation results in Changma earthquake district, this paper has in detail discussed basic features of the deformation Zone of Changma earthquake and the recent active characteristics of Changma fault. The Changma fault that has a long active history and dissects deeper erust is an ultralithosph—eric one and still active at present.The series of ridges and valleys were clearly dislocated in left—lateral way and their horizontal displacements which are divided into four sections indicate that four activitities took place at least along the fault.The fourth section of the displacements is 4.68 meters which is probably the result of 1932 Changma earthquake. The deformation Zone of Changma earthquake is relatively clear and basically extends along Ghangma fautt.The deformation zone consists of ground cracks, drumlin and steep cliffs and was accompanied with landslide and slump.The anticlockwise movement showen by mechanical analysis of the deformation Zone indicates left—lateral and tensile active characteristics of Changma fault Finaly, we studied the original model of Cehangma earthquake.

本文根据最新的现场考察结果,详细地讨论了1932年昌马7(1/2)级地震形变带的基本特征和昌马断裂最新活动特点。昌马断裂是活动历史悠久,切割地壳较深,现今仍在活动的超岩石圈断裂。我们发现该断裂使一系列山脊和冲沟发生了明显逆时针方向错动,其水平错距可分为四级,反映了昌马断裂至少经历了四次活动,最后一次的水平错距为4.68米,很可能是1932年昌马地震时造成的。昌马地震形变带比较清晰,其展布基本上与昌马断裂相吻合,形变带由地裂缝、鼓包和陡坎构成,并伴有滑坡和山崩现象。形变带组合关系的力学分析均显示了反时针错动,说明第四纪晚期昌马断裂是以左旋张扭性活动为特征。最后本文初步探讨了昌马地震成因模式。

Lishan piedmont fracture is a nearly westeast strike and northward dip normal fault developed on the north side of raised Lishan. The characteristics of the fracture deformation traces, the geomorphic marks, and the thickness of the Cenozoic Era sediment indicated that this fracture has got continuous tilted dip tensile movement under the control of regional tectonic gravitational tensor stress field since the later period of Quaternary. In the long-term of deformations it showed two kinds of motion, that is, creep slipping and stick slipping. Now, it is still following the first slipping.

骊山山前断裂是发育于骊山凸起北侧的一条近东西走向并向北倾斜的正断层。断裂形变遗迹,地貌标志、新生代沉积物的厚度变化特征表明,该断裂第四纪晚期以来,在区域构造引张应力场的控制下,一直作掀斜式的倾向拉张运动。在长期的形变过程中表现了蠕滑和粘滑两种活动方式。现在仍在以蠕动的方式运动着。
