Effects of Earthquake Essay

Primary effects are the immediate damage posed by the quake, such as collapsing buildings, roads and bridges, which may kill many people. Those booming enough to survive trick suffer badly from shock and panic. unoriginal effects are the after-effects of the earthquake, such as fires, tidal waves, landslides and disease.Fire earthquakes unmake gas pipes and electric cables, causing fires to spread. Broken water mains prevent the Fires universe extinguished. Fires spread very quickly in cities, especially in poor-quality hold areas where wooden buildings are common. Tsunamis an earthquake on the sea floor or close to the coast may cause huge waves. Landslides earthquakes often cause landslides, especially in steep river valleys and areas of weak rocks. Disease and famine wise(p) water supplies are often cut off causing typhoid fever and cholera. Lack of shelter and food causes much suffering. soil liquefaction when soils with a high school water content are violently sha ken they lose their automatic strength and behave like a fluid and so buildings can literally sink. Excellent clip 2011 Japan TsunamisMega tsunami caused by a landslide July 9th 1958ExplanationOutline causes A tsunami can be generated when destructive graduated table boundaries abruptly move and vertically displace the overlying water. It is very supposed(prenominal) that they can form at constructive or conservative casing boundaries. This is because constructive or conservative boundaries do not generally perturb the vertical displacement of the water column. Subduction zone related earthquakes generate the mass of all tsunamis. Tsunamis have a small wave height offshore, and a very long wavelength (often hundreds of kilometers long), which is why they generally pass unnoticed at sea, forming only a slight swell usually about three hundred mm above the normal sea surface. and they travel quickly at speeds over 700 km/h. They grow in height when they reach shallower water.
