1975年中国海城7.3级地震波及整个朝鲜半岛，乃至日本九州地区. 本文系统收集了该震有关资料，并通过整理分析勾画出其烈度分布，以探讨该震的震害特点. 在半岛的北部， 除局部地区为Ⅵ度之外，大部分地区为Ⅴ度区，其震害情况与相同烈度的典型特征基本相符； 半岛南部大部分地区为Ⅳ度区. 然而，韩国首尔等大城市，除高层建筑强烈振动之外，还有人出现眩晕症状等特别的感觉，个别街区变压器跳闸造成一时停电. 这些可能是大震的长周期波在远场的效应所致.   相似文献

The 1975 Haicheng M _S7.3 earthquake affected whole Korean Peninsula and even Kyushu, Japan. In this paper isoseismal map of this earthquake was drawn for these areas by sorting out and analyzing data systematically collected, furthermore, the characteristics of the earthquake damage were discussed. In the northern Korean Peninsula, the intensity is V in great majority of this area except local area with intensity VI, and the damage is basically in accordance with typical characteristics of corresponding intensity grade. In the southern Korean Peninsula, the intensity is IV in large part of the area, however, in some big cities such as Seoul etc., not only high buildings shook strongly, but also some people appeared perceptions such as feeling dizzy and so on, and electrical service was interrupted on one or two districts because of transformer tripping. These phenomena could be caused by the effect of long-period wave generated from a large earthquake on far-field.  相似文献
