Exciting news! We're transitioning to the Statewide California Earthquake Center. Our new website is under construction, but we'll continue using this website for SCEC business in the meantime. We're also archiving the Southern Center site to preserve its rich history. A new and improved platform is coming soon!

A Comparative Evaluation of Probabilistic Regional Seismic Loss Assessment Methods, Using Scenario Case Studies

Under Review 2013, SCEC Contribution #1828

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.
