This study compares current and developing probabilistic regional (portfolio) loss assessment methods. These comparisons are carried out for two scenario earthquake events. Of particular interest are: the impact of directly considering building responses versus basing losses on ground motion intensity; identifying best practices for predicting collapsed buildings; and examining the sensitivity of loss assessments to other methodological decisions related to building stock classification and exposure and key sources of uncertainty. On the basis of the identified strengths and weaknesses of the different regional loss assessment techniques, High-end and simplified methods are recommended for computing probabilistic regional seismic losses.
