WP2 aims to build physical models of three distributed systems as if they were independent of each other, and compute their earthquake vulnerability, risk, and resilience as they are deployed in a specific geographical setting. The geographical area under study is the Metropolitan Santiago and Valparaíso-Viña, which complexity is characterized by the existence of several critical networks for the country, such as transportation, ports, airports, utilities, communications, healthcare, education, among several others. To narrow down the scope of this project while preserving the generality of results, four interdependent DNS were selected:

For simplicity, these four networks are denoted hereafter as THEW networks. The rationale behind this selection was based on the following premises: (i) these networks are of utmost importance and research results may have strong impact in the overall resilience of the region; (ii) the three networks represent distinct domains and are treated differently, which should bring complexity and knowledge of models, analyses, and results that could carry over in the study of other networks; (iii) these networks are highly stressed in severe earthquakes, and hence, they become very interesting targets for evaluating risk and resilience; (iv) they have subtle but interesting  interdependencies, which is a differentiating aspect of this proposed research; and (v) there is substantial data available to include and validate the study of these networks, including their earthquake performance in 2010.
