Effects of Earthquakes

Fire

The strong vibrations caused by severe earthquakes strongly shake the buildings and thus causing severe fires in houses, mines and factories because of overturning of cooking gas, contact of live electric wires, churning of blast furnaces, displacement of other fire related and electric appliances.
Earthquakes destroy gas pipes and electric cables, causing fires to spread. Broken water mains makes it difficult to extinguish fires.

Floods

Strong seismic waves cause damage to dams thereby causing severe flash floods. Floods are secondary effects of earthquakes, if dams are damaged. Earthquakes may cause landslips to dam rivers, which collapse and cause floods.
Earthquakes destroy gas pipes and electric cables, causing fires to spread. Broken water mains makes it difficult to extinguish fires.

Soil liquefaction

Soil liquefaction occurs when, because of the shaking, water-saturated granular material, such as sand, temporarily loses its strength and transforms from a solid to a liquid. Soil liquefaction may cause rigid structures, like buildings and bridges, to tilt or sink into the liquefied deposits.
When soils with a high water content are violently shaken they lose their mechanical strength and behave like a fluid and so buildings can really sink.


What How Why

What is an electric current?

An electric current is a passage of electrons from one electrified body to another which is less charged. When too many electrons are generated, they can move.
