Life-fighting people are conquering the hostile nature and building monuments of civilization. But hostile nature hurts people's lives and property whenever it gets a chance. Sudden natural disasters destroy people's arranged families, many people's dreams are shattered. People may become accustomed to the adversity of some natural disasters, such as minor floods in the lowlands of
Bangladesh. But when the catastrophic floods swept away all the houses, treasures, fruits and crops, the normal life of the people was disrupted. People lost their lives in vain, crops were destroyed, huge damage was done to houses and livestock. Natural disasters refer to such events. These are due to extreme weather or geographical causes and result in severe damage to human life, resources or the natural environment. Different types of natural disasters: The constant radioactivity that occurs in nature or the mixture of toxic metals in the atmosphere is also a type of natural disaster, but we do not always notice it. Another type of natural disaster is called man-made disaster. Such as the Chernobyl nuclear accident. Floods caused by deforestation indirectly fall into man-made natural disasters. But natural disasters are usually known and discussed as those that happen suddenly and resulting in huge and massive disasters. Among the worst natural disasters in the world are cyclones, tidal surges, floods, droughts, landslides, earthquakes, volcanic eruptions, and so on. Disasters like this kill many people, disrupt the environment, disrupt the production system, and help others to save the lives of endangered people.
The severity of natural disasters: Earthquakes and volcanic eruptions have the greatest potential for landslides and destruction at the moment. The 1906 earthquake destroyed almost the entire city of San Francisco. A previous earthquake in 1986 killed at least 730,000 people in the Chinese province of Sanchi. The latest earthquake in Nepal in 2015 killed about 6,500 people in Nepal, China, India and Bangladesh. Volcanic eruptions also cause severe damage. In 69 AD, the cities of Herculaneum and Pompeii were completely destroyed by the eruption of the Vesuvius volcano in Italy. In 183, a volcanic eruption in Krakatoa, Indonesia, wiped out half an island, killing 36,000 people. The volcanic eruption is not just a vast area covered in burning lava and mud; Smoke, huge ashes and toxic gases cause severe adverse effects on the environment. Natural disasters include various types of cyclones, droughts, floods and natural fires. In 1970, a cyclone and tidal wave that swept over the southern part of Bangladesh killed 500,000 people. One and a half lakh people lost their lives on the Chittagong-Cox's Bazar beach in 1991. In 2006, Hurricane Sidr killed at least 2,218 people. Although floods in different parts of the world cause huge losses every year, the incidence of floods is highest in South Asia. The floods in Bangladesh are proof of that. The latest floods in 2016 were the worst in 26 years, affecting about 3.4 million people. The agricultural sector is most affected by the drought. As a result, the agrarian economy collapsed. The worst drought of the twentieth century hit the coast of Africa. This drought started in 1986 and continued for 12 years. A few years ago, Indonesia was hit by the worst drought of the century. As a result, heavy smoke and fog spread to large areas, including Malaysia, Singapore, Thailand, Brunei, and the Philippines. In these areas, normal activities became unusable month after month. As a result, agricultural crops are severely affected in these
Remedies and Prevention:
With proper preparation, it is possible to reduce the amount of damage by dealing with natural disasters and catastrophes in many cases. One of the most important part of this preparatory work is early warning. As a result of the groundbreaking advances in meteorology, it is now possible to provide early warning of floods, cyclones, flash
