Which event would most likely have the fewest casualties during the initial impact period?

• A. Large urban earthquake
• B. Large-scale hurricane surge
• C. Localized chemical spill in an industrial park far from people
• D. Nuclear power plant meltdown

Answer: (C)

Casualties in the initial impact are driven mainly by how many people are exposed to the hazard at the moment it occurs. A disaster that hits a densely populated area tends to cause many immediate injuries and deaths, because debris, flooding, or collapsing structures affect a large number of people quickly. An earthquake in a large city or a hurricane surge along a populated coastline exposes vast populations to danger right away, so the initial toll is high. A nuclear power plant meltdown can also produce significant early casualties if nearby populations are exposed or evacuated poorly, especially if containment fails or if evacuation isn’t timely. A chemical spill in an industrial park far from people means the immediate exposure is limited to a small number of workers in the park and nearby facilities. Outside that area, there aren’t many people to be harmed during the initial impact, so the early casualty count would be much lower.
