| 摘 要： | １９９９年伊慈米特７．４级地震地表破裂带表现清楚。在几何学特点上，它基本上由４个破裂段斜裂组合而成，沿破裂段可见不同的构造组相样式。在破裂段的阶区，主要发育张性构造。破裂段的最在工为５１ｍ，在运动学上，以右旋走滑运动为主，最大位错３．８ｍ‘走滑段最大垂直位错０．６ｍ。向观震中与地表最大位理合，基本上处于破裂带中间地段。地城寺表破裂带的动力学和几何学特征与震源机制解反映出来的结果相一致。

| Abstract: | The seism ic rupture zone of the Izm it earthquake of M S 7.4 is clear. Geom etrica- lly, it consists offour rupture segm ents in general, w hich are conjuncted obliquely, and various kinds oftectonic conjunction can be seen along the rupture segm ents.The steps ofthe rupture se- gm ents are tensionaltectonics in the m ain. The m axim um w idth ofthe rupture segm ents is 51 m . Kinem atically, right-lateralstrike slip m otion is dom inant;the m axim um dislocation is 3.8 m ;and the m axim um verticaldislocation ofthe strike slip segm ents is 0.6 m . Instrum entalepicenter coi- ncides w ith the location w here the m axim um surface dislocation took place, and is in the m iddle segm ent ofthe rupture zone on the w hole. The characteristics ofkinetics and geom etry of the ea- rthquake surface rupture zone are consistent w ith the results of focal-m echanism solution. |
