According to a recent UN report, seismic risk from large earthquakes continues to increase globally in line with infrastructure and population increase in developing nations. This implies the vulnerability is not decreasing relative to increased exposure. Specific examples include recent devastating earthquakes in Haiti and Sumatra in areas of known seismic hazard, but clearly this is part of a...

Risk assessment of urban infrastructure networks under natural and man-made hazards is often performed by repeated computational simulations based on random samples of hazard intensities and corresponding component status. This sampling-based approach may prevent near-real-time application of probabilistic methods to hazard mitigation of infrastructure networks and risk-informed decision suppor...
