Discuss five natural calamities that have the chance of occurring in the present world. What are their effects?
Natural Calamities
Earthquake – An Earthquake is caused due to pressure within the Earth. It can simply be defined as a sudden shaking of the Earth’s crust which lasts for a very short time. It sometimes causes severe devastation it is nearly impossible to predict the occurrence of an earthquake. As it usually occurs suddenly. Violent earthquakes are very dangerous and destructive. Serious damages to life and property are caused by them. The Himalaya young fold mountains in the northeast part of India their formation is not yet complete. Hence, the region of the Himalayas is very active. The area that comes under the maximum risk is the Kutch region of Gujarat and the Ganga Brahmaputra basin.
Cyclone – Circulatory events in the lower part of the atmosphere are generally termed cyclones. They originate over the warm ocean water of tropical and temperate regions. A cyclone occurs when a low-pressure air surrounded by high-pressure air. Thus, the wind blows at a very high speed towards the centre. These ones are destructive in nature which can grow at a velocity of 300 km per hour these winds are accompanied by heavy rain the movement and development of cyclones in India are observed and studied by the Indian Meteorological Department it is a government agency which also involves sending alert messages to airport, sea ports and fisherman.
Floods – A flood occurs when a large amount of water covers an area. It generally occurs due to heavy rainfall also occurs when a river overflows its water due to heavy rain. Flood is dangerous and causes damage to life and property. Floodwater submerges everything when it enters in area.

Drought – Drought can be defined as an extreme shortage of rainfall or water in and particular area. It directly affects the crop and results in a short shortage of food for humans and fodder for animals. In India, more than 70% of the total cultivated land is drought-prone. Drought is a common phenomenon in India, but due to better planning and drought management programs, their capacity to kill a large number of animals and people has been reduced.
Tsunami – When a large mass of water is displaced, a Tsunami develops. It occurs due to a volcanic eruption or an undersea earthquake. Tsunami travels at a high speed of around 500 to 1000 km per hour. Its speed decreases and its height increases when it enters the shallow coastal area. When a Tsunami wave reaches the coast, it appears as a Wall of water. The fast-moving wave can destroy houses and various structures in the coastal areas with its enormous energy. A great loss of life and property is caused by to tsunami. Tsunamis do not occur frequently, but they can occur at any point in time in the year. A tsunami can cause a large amount of destruction.
