To investigate innovative ways to bolster the resilience of the electrical grid, water systems and other lifelines and services, the National Science Foundation (NSF) has awarded grants totaling nearly $17 million to 10 projects researching the development of more resilient complex public infrastructures.
In the example above, "this image shows a section of downtown Salt Lake City, Utah, following a simulated earthquake. Potential safe movement paths around debris are shown as multi-color ribbons, calculated from a massively interactive agent-based model of likely behavior in the hour after the event. The height of the ribbons indicates the potential speed of movement possible; color denotes the buildings from which the trips might originate."
