What are natural disasters?

Natural disasters are those changes that occur in the environment around us. A natural disaster is an event that occurs unexpected. Therefore, it can cause major damages to property and even may cause the loss of a life. Few natural disasters that mankind frequently face are hurricanes, landslides, floods, earthquakes, tornadoes, and tsunamis.

What then are the causes for natural disasters?

The main reason for natural disasters are the change of the geographical structure of the earth and the different changes in climate. Another reason that adversely contributes for the increased natural disasters at present is the types of human habitat and the way man pollutes the environment around him.

What happens during a disaster?

Floods may cause so many homes and other buildings to wash out of that area. The most common natural disaster at present are landslides. Landslides or mudslides occur in areas where there are hills and steeps. People start digging hills using excavator grab to construct their houses blocking the water flow of these mountains. This then cause the water that flows within the mountain ranges to submerge to the earth making the soil softer. This then results in landslides.

Deforestation is another major reason for the balance of the eco system to change. This is where man for his selfish reasons destroy large forests areas. This drastically destroys the living space for many plants and homes of many endangered species. Deforestation causes climatic changes, and this then again adversely contributes towards the increase in natural disasters.
Sea erosion occurs due to the constructions that take place closer to the sea. People build large hotels and buildings in the beach clearing the beach area. They also destroy many sea plants for construction. This is a reason for tsunamis and landslides to occur and many lives to be lost.

How to act after a natural disaster.

Governments should act soon after a natural disaster. For example, there should be enough man power and technological power such as top quality excavator attachments to move away debris and to look for any person stuck in between debris. Many lives are lost during disasters due to the lack of knowledge people have about disasters. Governments should take necessary steps to educate people about natural disasters and teach them the necessary precautions to be taken during a natural disaster situation. Many lose their lives because they are alarmed and make the wrong decision during a disaster. For example, people should have the basic knowledge of not to stay inside their homes or a building during an earthquake.
