What Is earthquake: For natural reasons sometimes, the earth shakes suddenly. This sudden violent movement of the earth’s surface is called Earthquake.
Earthquake-prone countries: The earthquake-prone countries are Indonesia, Japan, China, Iran, etc. These countries are frequently hit by earthquakes. Houses and bridges in these countries are built shock-proof. The tsunami of 2004, dreadful earthquake of Pakistan and Kasmir of 2005 suggest us of a forthcoming massive earthquake.
Causes: Increase of pressure of the earth increases various reasons the pressure of the earth increases and causes an earthquake.
Land-Slide: Land-slide is one of the reasons for an earthquake.
The eruption of volcanoes: There is a deep relation between the earthquake and the eruption of volcanoes. When volcanic, emission of magma comes out with violent force, then the side space of it shakes out.
The volcanic substance inside the earth: There are some places inside the earth where the presence of volcanic substances are much. This cause an earthquake.
Effects of an earthquake: Earthquake reshapes the natural shapes-hills, plateaus, ocean, and levels. It demolished many beautiful buildings, roads, cities. It has rendered many flat, land into lakes and many seas into islands. Ages after ages, it has snatched away millions of valuable lives and billions of people homeless.

The risk of earthquake in Bangladesh: It is known to all that Bangladesh lies in an active earthquake zone. If the earthquake hits this area, countries like Nepal. India, Bhutan, Pakistan, and Bangladesh will be affected severely. There were 25, 18 and 4 recorded incidents of earthquakes in Bangladesh having the intensity of 6.7 and 8 respectively during the last 175 years. After 175 years of the great earthquake in Bangladesh, the country is once again in grave danger. This time if an earthquake takes place above 8 in the Richter Scale, the devastations will be even beyond speculation. It is feared that the millions of people will die if strong earthquakes hit the three major cities of Dhaka Chittagong and Sylhet.
Preparedness and awareness: Preparedness and awareness are very essential to face this disaster. Earthquake catastrophe is .quite different from the other natural calamities for which any kind of forecast or prediction is still impossible. The preparedness of government and the awareness of the people to tackle the aftermath earthquake sit11ation is very meagre. The government updated the house-building in order to check the maximum casualties. The concern authorities also emphasized on the preparation city maps indicating the soil structure. The buildings should be made active and time-befitting to meet the forth-coming danger like an earthquake.
Conclusion: The earthquake is. a great natural disaster. Within a few minutes, it can turn great cities into rivers. So, the awarenes is needed about the earthquake and its subsequent devastation.
