Seismic effect injuries may present as which of the following?

Seismic effect injuries primarily result from the physical impacts associated with the collapse of structures during an earthquake or similar seismic events. Blunt trauma, lacerations, or fractures are common injuries sustained when buildings and other structures fail, leading to the potential for debris to fall or the victim being caught up in a collapsing structure. These types of injuries are directly related to the mechanisms of collapse and the consequent forces exerted on individuals nearby.

The other options, while they describe real injuries that can occur in different contexts, do not specifically relate to the seismic effects seen during earthquakes. Burns and smoke inhalation are injuries typically associated with fire incidents, while electrical shocks and fall-related injuries would be more relevant to electrical accidents or slips and falls in various environments. Cuts and scrapes from debris might occur in broader contexts but do not specifically capture the nature of injuries prevalent in seismic events where significant structural failure is involved.
