    of connection between different infrastructure types is lacking within the earthquake engineering community. They identified a need for scalable tools that autonomously create an accurate database of all infrastructure components, including points of interdependency with other infrastructure components. Empowered with this complete mapping of an urban center’s infrastructure systems, powerful simulation technologies could model the time and spatial impacts of a seismic event at all length scales spanning from the component scale to the regional scale, and from disaster response to community recovery.

4. Mitigation: A large earthquake or tsunami in a highly populated region of the United States would cause massive damage to the built environment and communities in the region, and the resulting social and economic consequences would cascade across the country, particularly if major energy, transportation, or supply hubs are affected. Key characteristics of this Grand Challenge include developing strategies to measure, monitor, and model community vulnerability, motivations, and mitigation strategies, and establishing mitigation solutions for the community’s most vulnerable sectors. Participants suggested that mitigation solutions could be based on the use of a new generation of simulation tools and design solutions coupled with up-to-date information available from distributed sensing systems. Development of better approaches for renewal and retrofit of the built environment’s most vulnerable sectors would help ensure a safer environment and a more resilient community.

5. Design Tools: Participants suggested that developing and exploiting new emerging materials and innovative structural concepts and integrating them within design tools could dramatically improve the performance of all types of infrastructure and increase earthquake resilience in ways that are also sustainable. There is a wide range of sustainable highly resilient, new materials that can offer opportunities to significantly change the way infrastructure is designed and constructed. Harnessing the power of
