Recent events such as the 2011 Christchurch, New Zealand earthquake, the 2011 Great Tohoku, Japan earthquake and tsunami, and Superstorm Sandy in 2012 have highlighted the need to better understand and model community resilience. This is particularly true with regard to interdependencies among physical infrastructure components and systems that exacerbate their lack of functionality and delay community recovery. The National Institute of Standards and Technology (NIST) funded the multi university five-year Center of Excellence for Risk-Based Community Resilience Planning (CoE), headquartered at Colorado State University. The Center’s purpose is to (i) develop a computational environment with fully integrated supporting databases to identify, study and understand the key attributes that make communities resilient; (ii) standardize data ontologies for community resilience; (iii) validate the computational environment through hindcasting of events and resilience-based field studies; and (iv) optimize resilience enhancement strategies utilizing these tools and databases. This paper presents a brief overview of the CoE and its current research accomplishments, including a description of the considered testbed communities. In this paper, we discuss the role that robustness to earthquakes and tsunamis play on community resilience including recovery, illustrating the process at the community level.
