The seismic vulnerability index (K_g) is a parameter that depends on the dynamic properties of soil. With this parameter, it is possible to evaluate the vulnerability of a point-based site under strong ground motion. Since it is related to the natural vibration period and amplification factor, the parameter can be calculated for both soil and structure. In this study, HVSR microtremor measurements are recorded at more than 200 points in the Van region to generate a seismic vulnerability index map. After generating the map, it is determined that the hazard potential and seismic vulnerability index is high at the sites close to Van Lake and at the densely populated city center. Damage information of the buildings investigated after the 2011 Van earthquakes (M_w = 7.1) are placed on the seismic vulnerability index map and it is realized that there may be a correlation between the damage and the seismic vulnerability index. There is a high correlation, approximately 80 percent, between the damage rate map based on the damaged building data and the K_g values. In addition, vulnerability indexes of buildings are calculated and the eff ect of local soil conditions and building properties on the damage levels are determined. From the results of this study and the site observations after the 2011 Van earthquakes, it is found that structural damage is not only structure-dependent but is also related to the dynamic behavior of soil layers and local soil conditions.

土耳其东部范城建筑物破坏评估中地震易损性指数（K g）的可用性

地震脆弱性指数（K _g）是取决于土壤动力学特性的参数。使用此参数，可以评估在强地面运动下基于点的站点的脆弱性。由于它与自然振动周期和放大系数有关，因此可以为土壤和结构计算参数。在这项研究中，在范地区记录了200多个点的HVSR微震测量结果，以生成地震易损性指数图。生成地图后，可以确定在范湖附近的地点和人口稠密的市中心，潜在危险和地震脆弱性指数较高。2011年范克地震（M _w= 7.1）放置在地震脆弱性指数图上，并且意识到在破坏与地震脆弱性指数之间可能存在相关性。基于损坏的建筑物数据的损坏率图与K _g值之间存在高度相关性，大约为80％。此外，计算建筑物的脆弱性指数，并确定当地土壤条件和建筑物特性对破坏程度的影响。从这项研究的结果和2011年范地震后的现场观察，发现结构破坏不仅取决于结构，而且还与土壤层的动态行为和当地土壤条件有关。
