Although houses are the most affected physical element by landslides, studies on the vulnerability of houses are limited, particularly in the Himalayan region. The present research concentrates on assessing the physical vulnerability of the houses to landslide hazard modifying an indicator-based approach. In the methodological framework, the vulnerability index is composed of the resistance capacity of the houses and their exposures. The study introduced several sets of geomorphic conditions on the basis of which the resistance-indicators were evaluated and adopted using Fuzzy - Analytic Hierarchy Process (Fuzzy-AHP) to measure the resistance index of the houses. The method was carried out on 332 houses in the active landslide-prone sites of the Kalimpong region of the Himalaya, India. The data was collected based on field surveys using GPS, field mapping, and interviews of local people. The result shows that about 50% of the houses are highly vulnerable. Even though their influences vary at micro-level, the degree of vulnerability highly varied across the houses due to the combined effect of exposure and resistance. We validated the result with the relation between the vulnerability index and the damaged households using the R - index method. The result reflects that the partly damaged households and the vulnerability index have a positive association. Finally, the study demonstrates that improving the resistance of houses and mitigation of landslide is critical to manage the vulnerability of the houses.

尽管房屋是山体滑坡影响最大的物理要素，但对房屋脆弱性的研究仍然有限，特别是在喜马拉雅地区。本研究集中在评估房屋对滑坡灾害的物理脆弱性进行评估，并采用了基于指标的方法。在方法框架中，脆弱性指数由房屋的抵抗力及其承受的风险组成。该研究介绍了几组地貌条件，在此基础上评估了阻力指标，并使用模糊层次分析法（Fuzzy-AHP）来测量房屋的阻力指标。该方法是在印度喜马拉雅山Kal伦堡地区活跃滑坡易发地点的332栋房屋上进行的。数据是根据使用GPS进行的实地调查收集的，实地测绘以及对当地人的采访。结果表明，大约50％的房屋非常脆弱。尽管它们的影响在微观层面上有所不同，但由于暴露和抵抗的综合作用，整个房屋的脆弱程度也存在很大差异。我们使用R指数方法，通过脆弱性指数与受损家庭之间的关系来验证结果。结果表明，部分受损家庭与脆弱性指数之间存在正相关关系。最后，研究表明，改善房屋的抵抗力和减轻滑坡对管理房屋的脆弱性至关重要。由于暴露和抵抗的综合作用，整个房屋的脆弱程度差异很大。我们使用R指数方法，通过脆弱性指数与受损家庭之间的关系来验证结果。结果表明，部分受损家庭与脆弱性指数之间存在正相关关系。最后，研究表明，改善房屋的抵抗力和减轻滑坡对管理房屋的脆弱性至关重要。由于暴露和抵抗的综合作用，整个房屋的脆弱程度差异很大。我们使用R指数方法，通过脆弱性指数与受损家庭之间的关系来验证结果。结果表明，部分受损家庭与脆弱性指数之间存在正相关关系。最后，研究表明，改善房屋的抵抗力和减轻滑坡对管理房屋的脆弱性至关重要。
