Earthquake

Earthquake refers to the shuddering of the earth’s surface which is caused by the quick movement of the earth’s external layer. While the earth’s energy is suddenly freed within the earth, it results in earthquake. The energy is sent out to the outer surface of the earth by earthquake waves. The destruction of earthquake varies from the degree of shake it creates. An Earthquake of moderate power can turn up to be a great threat for us. A severe earthquake can have the potential to cause widespread destruction of houses and properties. Some regions are prone to earthquake while others are comparatively safe from this natural disaster. Nowadays it is frequently felt in Bangladesh. Some countries like Japan, Iran, Indonesia etc are frequently hit by earthquake. Houses, high-rise buildings and bridges in some of these countries are built shockproof. Since an earthquake attacks abruptly, it is not possible to forecast the occurrence of it. A severe earthquake causes extensive destruction of houses and properties. Adequate precautions such as education, emergency planning can limit the loss of life and decrease the damage caused by earthquakes. Often several quakes hit a place at a place at short intervals. So after a quake, people should live tents in open fields. When a severe earthquake hits a populous city, thousands of people are killed and injured. Many people get trapped in the broken houses and it takes several days to rescue them. Since earthquake cannot be prevented, the only way to get rid of the depredation of this natural disaster is to build houses, bridges and roads in such a way that the can absorb the tremors. Proper structural designs should be followed and building codes should be followed to reduce death, injury and loss caused by earthquake.
