Earthquake

An earthquake causes a great duster. It is a sudden movement of a part of the earth's surface caused by deep crack in the earth or by volcanic eruption. Some regions of the earth are prone to earthquakes while others are comparatively safe from this natural disaster. Some countries like Japan, Iran etc. are frequently hit by earthquakes. Houses and bridges in these countries are built shock proof. Forecast regarding the occurrence of an earthquake is not possible. A severe earthquake causes widespread destruction of houses, and properties. People are crushed under the broken houses. Often several quakes hit a place at short intervals. So after a quake people live in tents on open fields. When a severe quake hits a populous city, thousands of people are killed and injured. Many people get trapped in the broken houses and it takes days to rescue them. The only way to get rid of the ravages Of this natural disaster is to build houses, bridges and roads in such a way that they can resist the tremors.
