The weather on earth is very unpredictable. You never know when and where the next natural calamity will occur. One day all is fine and suddenly the very next day it starts raining heavily causing massive flood. A Natural Disaster can be called as a natural phenomenon which can occur anytime and at any place. It is unpredictable and causes massive destruction within seconds. All the natural forces act on human beings as well as animals and kill many lives. A Natural Disaster can occur in many forms like floods, earthquakes, volcano eruption, hurricanes, etc to name a few. As such, a disaster can be said to be something that will have a long lasting effect on the environment as well as our minds. Get to know more about Natural Disasters from the given report.
Scientists have spent years discovering the reasons and finding solutions to natural disasters, but all in vain. They have succeeded to some extent, but that is not sufficient to make the earth safe and free of all dangers. Many types of natural calamities occur on Earth every now and then. To start with, landslides are very disastrous as they directly affect the ground and also the rocks beneath it. When earthquakes occur or when there is volcanic eruption, mudslides or mudflow takes place which loosens the soil’s grip on the land and can cause landslides. Another type of calamity is avalanche. It is a geographical hazard in which a large mass of snow or huge rocks along with ice fall down the mountainside. Due to rain or many other factors the snow slides down. While sliding it accumulates more and more snow with it making it a huge mass which is very destructive in nature. In winter seasons, this is the most dangerous thing that can happen anytime in mountain and hilly areas. At times, the snow which is light in weight mixes with the air and forms a powder cloud. Avalanches along with powder cloud are more dangerous and disastrous.
Droughts are another form of calamities which cause colossal damage to the earth. It is a condition where an area or a state suffers from an acute deficiency of water. This can go on for few days or for months to count. If a particular area receives low rainfall or doesn’t receive rainfall at all for many years then the water content in land as well as the plants drops below its minimum level in such a way that living there becomes impossible. This state of the land can cause a highly negative effect on the ecosystem. Not only this, the agricultural areas are stranded and of no use until the rainfall occurs and restores the normal condition. There have been cases when the droughts have stayed for years. But, the main factor is the intensity of droughts and not its duration.
Wildfires are also very harmful to the environment. Although they don’t occur that frequently, they cause much damage to the wildlife and environment. Wildfires are the uncontrolled fires which grow fast in the forest areas. Many factors have been observed when it comes to wildfire. Most common are the lightening and human carelessness. We leave burnt cigarettes and burned ashes in forests. When huge winds blow, the trees catch fire which spreads very fast. This can be a huge danger to the people living near such wildfire prone areas. Not only this, wildfire is also capable of burning away the building and houses if they are of greater intensity.
Floods and its more disastrous version, the tsunami, are both very dangerous to life and property. When there is movement of the rocks beneath the earth due to the volcanic eruptions, this disturbs the sea level and its waves are so much affected that they lose control and cause huge waves to run across its nearby areas. It is not just a simple tidal wave, but a huge gigantic and disastrous one. It can cause damage with much greater intensity than you can imagine. When we talk of tsunami, then we should also be aware of the volcanic eruptions which are very poisonous in nature. When the volcano is active it lets out lava in huge quantities. At some places, small quantities of eruptions are experienced daily, while in some areas you will find a sudden release which can spread over a large area. Some of them are so huge that they create clouds of ash and smoke, and the steam flows down the mountains at a high speed such that all the nearby areas are burnt to death.
You must have heard of tornados occurring in some areas. They are very violent winds which flow at a very high speed of 200 to 400 mph or even more than this speed. They can occur once in a while with a high force, or they can happen in small bouts of winds. Another very dangerous natural calamity is earthquake which takes place when there is some movement in the earth’s crust which results in seismographic waves. You can measure the magnitude of the earthquake on a Richter scale. If the value is above 7 then it results in a very serious earthquake. On the surface of the Earth, you can experience the shaking of buildings and trees. There are cases when the buildings have been dumped in the ground. Hurricanes are equally dangerous to the natural resources. Hurricanes and cyclone is the same thing with different names.
In this century, many disastrous calamities have taken place throughout the globe. Some of them were of such a high intensity that till date you can see its effect on the people who have sustained them. In 2010, the Haiti earthquake had knocked the south west of Port-Au-Prince. It was the strongest earthquake since 1770 in that area. It took away homes of about 2 million people, killing lives of 2 lakh people. A lot of money and labor was spent on restoring the condition. In 2008, the Cyclone Nargis hit the Indian Ocean. The country of Myanmar received a huge landfall and the Ayeyarwady Delta region was completely destroyed. In this incident, almost 84500 people were killed. Before that, Pakistan had also fallen prey to a huge calamity in 2005. The epicenter of this earthquake was near the state of Kashmir. But this calamity would have made less damage if the buildings were strong enough to sustain the sudden movement.
Hurricanes have not occurred so frequently but one of the deadliest hurricanes was that in the Gulf coast in year 2005. It was one of the strongest hurricanes in the country of U.S. This caused a huge damage to live and property which was irrecoverable. Nevado Del Ruiz Volcano Eruption, which took place in the year 1985 was second largest volcano eruption to occur in the 20th century. It was of huge intensity and took numerous lives. The count was approximate 25,000. Before this calamity, in 1993, Hurricane Andrew took its form. It was a tropical wave that occurred in the west coast of Africa in the month of August. Initially it was of low intensity due to the wind shear but in successive days it formed a destructive tropical cyclone and was given the name Hurricane Andrew. This caused a property damage of about US $26 billion. Its intensity was almost same as that of Katrina and Wilma.
How can one forget the most recent natural calamity that took place in Jana and areas around it and took away the lives of countless people? It took place on 25th April killing more than 8,000 people and injuring almost 19,000 people. It was of a very high magnitude. This was the worst of the earthquakes Nepal had ever experienced in the history. Geophysicists had predicted that Nepal was prone to such a calamity in this decade. Many factors like its geology as well as the architecture were responsible for his calamity to take place. Many villages were scattered and thousands of people are still homeless seeking help for a living. It was of such a huge intensity that its aftershocks were experienced in Mount Everest and also in north-eastern areas of India like Assam, Siliguri and Kolkata.
Thus, natural calamities have been there on the Earth since a long time and will continue to occur. Some of them are due to man’s ignorance while some others have occurred due to wars and terrorism. But, of course, some of them are purely Mother Nature’s wish. There are many factors on the basis of which you can rate a disaster to be of medium or high intensity. From hurricanes to tsunami, from earthquakes to typhoons, all of them are horrifying in their own way. Disaster Management teams need to be set up to manage all sorts of disasters most effectively and try and make the effect of the calamity as minimal as possible. Proper education and awareness in these matters and effective precautionary measures is the only solution.
A natural calamity is a form of disaster that causes huge destruction to life and property all over the areas affected by it. It can be of various forms, and for reasons inevitable. Most of them cannot even be controlled or predicted beforehand.
