the cause and effects of earthquakes.

(Bolt . Some of the evidences were seen during the filling of Aswan High Dam in Egypt , Kariba Dam between Zimbabwe and Zambia and the Hoover Dam in the United States

Effects of earthquakes

There are several effects of earthquakes which include geological changes , damages to structures and several effect on human and animal life . The effects are shaking and ground rupture , landslides avalanches ,fires ,soil liquefaction ,Tsunami ,floods ,diseases and human impacts . Earthquake effects can also be classified as direct effects or secondary effects . Directs effects are those effects that occurred

due to the direct influence of the deformed area of earth and this effect is usually limited to the site of the earthquake or the area of the exposed fault rupture (Louie . Secondary effects are those effects that are not directly related to the area of the earth surface with fault movement but they usually result from transmission of waves (seismic waves ) from the area of faults . It is the most common effect associated with earquakes . Secondary effects are : seismic shaking , landslides liquefaction , fissuring , settlement and triggering of aftershocks and additional earthquakes (louie

Seismic shaking and groud rupture

This is the main effects of earthquakes and it usually results in severe destruction of man made structures such as houses , bridges and some other structures . The severity of this shaking depends on the magnitude of the earthquake , the distance of the local effects to the epicentre and other factors such as geological and geomorphological conditions that can increase or decrease the intensity of the waves that is being propagated . Ground rupture can be seen as a visible breaking or displacement on the earth surface and this normally result in a major risk to dams , brigdes and nuclear power station Landslides , liquefactions and avalanches Fire

Earthquakes can lead to post-earthquake fire...
