The procedure to assess seismic risk and estimate insured and uninsured losses is well established. It mainly consists of combining two major components: the estimated seismic hazard and the developed vulnerability models. This proposal is focused on the seismic vulnerability models that define the damage level for a given ground motion measure. The development of such a model is simple if there are sufficient well documented experimental full scale "test" results. However, this is typically not the case, and often the assigned vulnerability models for buildings of different types and geometries can only be developed based on opinion of experts or inferred from rare historical earthquake damage surveys in turn related to macroseismic intensity (such as Modified Mercalli Intensity or MMI). The difficulty is compounded by that no single construction practice norm is universally implemented, and different government agencies, insurance industry players, and/or research groups prefer different vulnerability models. However, important quantifications of the differences among the available vulnerability models are not available or accessible.

评估地震风险和估计保险和未保险损失的程序已经建立。 它主要包括两个主要组成部分：估计的地震危险性和开发的脆弱性模型。该建议的重点是地震易损性模型，定义了一个给定的地面运动措施的损害程度。如果有充分的、有据可查的实验性全尺寸“测试”结果，则这种模型的开发是简单的。然而，通常情况并非如此，通常只能根据专家的意见或从与宏观地震烈度（如修正的麦加利烈度或MMI）相关的罕见历史地震破坏调查中推断出不同类型和几何形状的建筑物的指定易损性模型。困难是复杂的，没有一个单一的建筑实践规范是普遍实施的，不同的政府机构，保险行业的参与者，和/或研究团体喜欢不同的脆弱性模型。然而，现有脆弱性模型之间差异的重要量化数据尚不存在或无法获得。
