Which of the following is NOT typically a flood-related hazard?

• A. Contaminated water
• B. Mold
• C. Sewage overflow
• D. Earthquake induced ground shaking

Answer: (D)

Flood-related hazards arise from the water itself and the moisture it leaves behind. Contaminated water brings pathogens and pollutants that threaten health. Persistent moisture promotes mold growth, which can affect indoor air quality and structure. Sewage overflow happens when drainage systems are overwhelmed, introducing waste and pathogens into living spaces. Earthquake-induced ground shaking, on the other hand, is a seismic hazard whose main risks come from the shaking of the ground and the damage it causes to buildings and infrastructure, not from floodwaters. So it is not typically considered a flood-related hazard.
