Checking for Damages

in Homes after an

Earthquake

After a major earthquake, checking the conditions of structures is

important in order to assess their safety and functionality. Buildings

and houses already damaged by the earthquake can receive

additional damage from aftershocks. Walking around the house and

inspecting the walls for cracks, broken windows, detached doors,

and leaning chimneys is a smart move for homeowners who have

just experienced an earthquake.

Exteriors

Houses built from weak foundation most of the time shift from its original place.

Leaning or tilted houses may collapse anytime and can lead to injuries or even death

for people who have not yet

evacuated the place. Severe

cracks and openings, especially

on the ground, may lead to

serious problems, as these

cracks may get bigger from

vibrations from passing trucks,

buses, and other big vehicles.

Interiors

Doors and windows may be harder to open or difficult

to shut properly after a major tremor. Poorly aligned

window frames, loosened exterior sidings, and interior

wall cracks may pose danger if they fall. One

frightening thing to see is if the floor separates from

walls or stairwells, as these may collapse anytime and

the whole structure as well.

Utilities

Sagging power lines, leaning

water heaters, unsecure water

connections, pipes, faucets and

toilets can compromise safety,

but gas leaks are especially

dangerous. Using candles,

lighters, matches and any other

open flames near the leaks can

cause fire.

Chimneys

Unnoticed damages, like those in the chimney, can lead to a fire or collapse during

aftershocks. Cracks and damages, especially where the siding meets the chimney, can

trigger such incidents. Older chimneys look safe, but can collapse into individual

bricks.

Experiencing one big earthquake may not be the end of it, as aftershocks can still

occur months after. These can cause additional damage and compromise the safety of

those living in the house, that is why checking the house exteriors, interiors, and even

utilities and chimneys is important after a major shake.
