EARTHQUAKE HAZARDS.

 BUiLDiNGS CAN BE DAMAGED.


The first main earthquake hazard (danger) is the effect of ground shaking. Buildings can be damaged by the shaking itself or by the ground beneath them settling to a different level than it was before the earthquake (subsidence).Buildings can be damaged by strong surface waves making the ground heave and lurch. Any buildings in the path of these surface waves can lean or tip over from all the movement. The ground shaking may also cause landslides, mudslides, and avalanches on steeper hills or mountains, all of which can damage buildings and hurt people.






Falling Objects: Objects can fall from shelves, ceilings, building, etc. and easily injure humans or other animals.
Fires: Fires are caused by disruption of electric, gas, or oil lines which can rupture from the ground shaking.
Avalanches:Due to the ground shaking, avalanches cause snow to behave like a liquid and slide down a mountain. Avalanches can bury mountain side homes and destroy forests.
