The widespread impact of a catastrophic incident makes it one of the most important topics in emergency management today. A catastrophic incident may be a single incident or a series of incidents and is defined as a natural or manmade event, including terrorism, that results in extraordinary levels of casualties, damage, or disruption severely affecting the population, infrastructure, environment, economy, and government functions.
A catastrophic incident in California would likely:
• Result in thousands of casualties with many requiring immediate lifesaving support from outside the affected area.
• Displace tens of thousands of people and isolate large areas from normal supply channels.
• Almost immediately overwhelm response and recovery resources normally available to local, state, tribal, and private-sector governments or entities, and require extended strategies and outside capabilities.
• Cause massive disruption of critical infrastructure such as energy, transportation, telecommunications, medical response, and health care systems.
• Significantly interrupt governmental operations and emergency services to such an extent that state or national security could be threatened.
• Result in long-term economic impacts to the incident area, California, and Nation.
These factors drive the need for coordinated disaster planning that includes potential federal assistance. Following a catastrophic incident in California, a joint state and federal organization will provide lifesaving, life-sustaining, and other resources necessary to alleviate the consequences of the incident and encourage the recovery of the affected areas.
