The surface or the structure of the earth does not always remain the same. It changes time to time. Some changes may be very small but some may be very big. There are various types of natural disaster that occurs in the earth. Some may have positive effects or some may have negative effects. Some may balance the environment but some may imbalance the environment. Some disaster may occur time to time but some may occur after a long period of time.There are various internal and external factors that cause the natural disasters. Earthquake in Nepal, tsunami in Bangladesh, earthquake and tsunami in Japan, flood in Sindhupalchowk of Nepal, etc are the examples of the natural disaster.
There are various types of natural disaster. Some disasters are small and do not harm the ecosystem and human civilization but some are very big and destroys the ecosystem and human civilization. Some of the big disasters are volcano,earthquake, tsunami etc. whose effects are very large. It causes huge loss of life and damage. It takes very long time to recover from their effects. Natural disasters are not only caused by nature but the human living on earth are also responsible for the natural disaster. Disasters like flood, landslide, burning of forest, etc are caused due to human activities like deforestation, unplanned industrialization, and urbanization, pollution etc.
The disaster caused by nature are called natural disaster. Disasters like the earthquake, volcano, tsunami, etc are the some examples of natural hazards. They cause huge loss of life and damage the environment.
We cannot only blame nature for happening of the natural disaster. Some disasters are also caused due to human activities. Some of the examples of disasters caused by human activities are the landslide, forest fire, desertification, drying out of sources of water, global warming, vehicles accident, etc.
Management of Natural Hazards
We cannot only stay watching natural disaster and loss of human life and damage to the environment. Though we cannot stop the natural disaster from occurring but we can minimize its effects on human life and other members of the ecosystem. There are various ways to minimize the effects of natural disaster which are discussed below,
Management of man-made hazards.
Activities that should be done before disaster
The government should warn the people about the place where there is a high chance of occurring natural disaster. We should be mentally and physically pre- planned about the effects and management of the natural disaster. We should be aware of the effects of natural disaster and we should make our management according to the effects of natural disaster. For man- made hazards, we should not pollute the environment, we should warn the people about the area where there is a high chance of landslide and such are should be properly managed. Strick law should be made and implemented for the protection and preservation of forest, unplanned industrialization and urbanization.
Activities that should be done while hazard
We should be aware and help and support others as much as possible. We should stay very strongly and bravely by uniting and staying together.
Activities that should be done after disaster
As much as fast, we should rescue the people that are affected by natural disasters. Immediate health support should be given to them. We should also provide them emotional support. We should inform the rescue team and assist them. After the disaster, various people loss their shelter, food, clothes etc. So, we should provide them food mostly dry and packed food, pure drinking water, medicines, clothes , tents for shelter, light etc. After the disaster, we should conduct programs for help and support to the victim and reconstruction of the damaged places. The government should provide financial support to the victims to start their new life in a new place. Monument, statue or park should be made to remember the person who lost their life during the disaster.
There is a large mass of snow in a mountain region. They are very large in size and increases its size when the snow falls. In Nepal, there are a huge amount of snow. During summer season or due to global warming the temperature of the mountain region becomes very high due to which the snow starts melting. Asa result, new lakes are formed which are known as glacial lakes. There are many glacial lakes in mountain regions of Nepal. Some of them have already burst whereas some of them are at high chance of busting which is very dangerous.
