When masonry construction collapses, the debris can travel some distance and cause what?

• A. The collapse of other structures or objects
• B. Ground vibrations only
• C. No other effects
• D. Local hazards

Answer: (A)

When masonry fails, the resulting debris carries momentum and can travel beyond the immediate collapse area, posing a risk to nearby structures and objects. That outward travel can strike and overwhelm adjacent walls, roofs, or components, leading to secondary collapses or damage to other buildings, vehicles, or utilities. Ground vibrations are part of the hazard, but they don’t fully capture the risk of debris causing additional collapses. So the most direct and significant consequence is the collapse or damage of other structures or objects caused by flying debris.
