迄今为止的证据表明,山区在相当大的范围内存在的大多数大的地形变动是伴随大地震而发生的,而且是由大地震而引起的.事实上,总的说来没有一个大地震(震级>6.5,烈度>8)发生不引起严重的地形变化,而这些地形变动常常就是一些较小的地震事件.按我们的分类,由地震引起的严重地形变动包括地滑、岩滑、泥石流、下陷深涧以及大范围的滑移的土体.我们知道在苏联中亚地区所有这类地震断裂引起的地形变动均是由过去几个世纪以及本世纪的大地震诱发的.有一种地形变动严重程度的计算准则(以及建筑物和人口受损失的程度)是地震震级与烈度的函数.我们面对的任务是确定与大地震有关的
The evidence so far shows that most of the large topographic changes that exist over a considerable area of the mountain area occurred with large earthquakes and were caused by large earthquakes. In fact, there was in fact no major earthquake Magnitude> 6.5, intensity> 8) did not cause serious topographic changes, and these topographic changes are often minor earthquakes. According to our classification, severe terrain changes caused by earthquakes include ground slip, rock slide, debris flow, sag Deep streams, and a wide range of slippery soils, and we know that all the terrain changes caused by such earthquakes in Central Asia in the Soviet Union were induced by the earthquakes of the past centuries and the present century. (As well as the extent to which buildings and populations are damaged) is a function of the magnitude and intensity of the earthquake, and the task we face is to determine the magnitude of the earthquake
