With numerous technological and organizational advances, the amount of rapidly available information streams surrounding regional impacts after an earthquake has increased dramatically. Specifically, the post-disaster damage is either predicted with rapid loss models, estimated with remote sensing information, or measured through field surveys. SURI is developing a methodology to integrate these data sources to a single spatial distribution of a tangible damage metric which can inform response and recovery decisions.

This is part of a broader collaboration in which we are using the 2015 earthquake in Nepal as a case study to analyze post-disaster damages (disaster-induced losses) and needs (disaster-induced vulnerability).
