FYI: despite popular misconception, "casualty" doesn't imply death. A casualty of war, for example, might actually refer to someone who is wounded/maimed/etc.

FYI: despite popular misconception, "casualty" doesn't imply death. A casualty of war, for example, might actually refer to someone who is wounded/maimed/etc. but still survives. If a house is consumed by lava and the occupant becomes displaced/homeless, it could reasonably be argued that it didn't result in zero casualties. Same goes for other things that might be more commonly understood as "collateral damage".
