What are the direct hazards of earthquakes?

Answer 1

Buildings tend to fall down in big earthquakes, and often kill the people living in them.

Roads are often buckled or split, and bridges have been known to fall down or break. For example, in the 1989 Loma Prieta earthquake in California, one segment of the Oakland to San Francisco Bay Bridge collapsed, killing one motorist, and a long segment of elevated freeway in Oakland collapsed, crushing the cars on the lower level as the upper deck fell down.

Earthquakes sometimes start fires when buildings collapse, and all too often the water system is also broken, disabling some or all of the fire hydrants.

Answer 2

There are lots of affects that can come from earthquakes.

Tsunamis- Earthquakes from under the sea that create a huge tidal wave.

Roads and transport stops-Lots of rubble and rock can fall on train tracks and roads, stopping transport altogether.

No transport-If there is no transport how are the emergency services going to get to the scene? In poor countries they won't be able to afford helicopters.

Hospitals and fire stations out of use-In an earthquake many hospitals and fire stations get ruined by falling building and the shaking of the ground. This means fires can't be put out and people can't have their wounds from the earthquake healed.

No electricity-During earthquakes power lines and pylons get ruined so electricity is not avalible. This means no one can even call the emergency services.

If you still need more information look up the earthquakes in Haiti and the tsunami in Japan.
