As human population has continued to concentrate in urban areas, the number of people and the value of property affected by disasters, both natural and human-generated, have grown as well. Earthquakes, floods, hurricanes, cyclones, tornadoes, and forest fires have all taken their toll so have such anthropogenic disasters as pipeline failures, industrial spills, and terrorist attacks.

The contents of this volume consist of papers presented at the fourth in a series of conferences convened to assess the potential risk from various disasters and discuss ways to prevent or mitigate damage. The papers have been contributed by experts on public health, security, and disaster management from academia, industry, and government.

Topics covered include: Disaster Analysis; Disaster Monitoring and Mitigation; Emergency Preparedness; Risk Assessment and Mitigation; Risk and Security; Safety and Resilience; Socio-economic Issues; Case Studies.
