中文摘要：

对2003年9月27日发生在俄罗斯阿尔泰南部山区的强烈地震在宏观烈度、地质和地震学方面的特征进行了综述。该次地震对震中地区的建筑物造成了损害，在地表形成了NWW走向的断裂带，此断裂带在楚亚北部地区向东延伸20km。次生地震变形表现为极震区内出现滚石、滑坡、喷水冒沙现象。震源构造的初步研究结果表明戈尔诺一阿尔泰地区是和蒙古一戈壁阿尔泰地区相连接。戈壁阿尔泰地区曾发生过多次震级7．0以上的地震，阿尔泰山脉系统实际上是一个发生高震级的地震构造带。

英文摘要：

The article summarizes the macro intensity, geological and seismological character of strong earthquake of Sep. 27,2003 occurring in mountainous area of southern Altai in Russia. The event damaged buildings around the epicenter, and generated NWW fault on the surface, which extends 20 krn to the east in northern Chuya region. Secondary deformation is characteristics of rolling rocks, landslide and spewing water and emitting sand in the magistoseismic area. Research on the source tectonic shows that Gorno-Altai region and Mongolia-Gobi Altai region are conjoint.There occurred several events with Ms≥7.0 in the Gobi Altai region. We think Altai mountain system is a seismic belt occurring large earthquake.
