We all are familiar with the term “natural disaster.” A significant adverse event that occurs from the natural geologic processes of the Earth is known as Natural Disaster. Some widespread examples of natural disasters are; earthquakes, tsunamis, floods, volcanic eruptions, droughts, tornado/ cyclones, landslides, forest fire, thunderstorms, etc. Some of these natural disasters take place all of a sudden. It causes the loss of many lives and properties.
Everything happens for a reason!
Geologists have found out the reasons behind natural disasters. Some of them are predictable, such as; meteorologists can aware us if there is a chance of a cyclone. If the temperature is too hot, then they will predict about occurring drought. Just like this way, we are describing the reasons behind natural disasters downwards:
Do you know what is under the Earth’s crust? There are hot molten rocks (also known as magma) under the crust. When these molten rock materials start coming out on the Earth’s surface, this process is called Volcanism. It is well known as Volcanic Eruption. The temperature remains higher than you can imagine! This disaster is an unpredictable natural disaster.
Forest fire is a term that might be new to some of us. When any fire occurs in a forest due to some natural reason, it is called forest fire. Forest fire is dangerous because it is uncontrollable. It destroys nearby vegetation and associated wildlife.
Earthquake is another hazardous natural event that can take place anytime, anywhere! It feels like a sudden, intense vibration. There are several pieces of land under the Earth’s surface. These land pieces are called tectonic plates. Most earthquakes occur due to the movement of these plates. Besides this reason, it may also happen because of the volcanic eruption. Whenever Earth releases tremendous energy, it left an impact on the earthquake.
Underwater earthquakes or volcanic eruptions are responsible for Tsunami. Large waves are seen at the time of the Tsunami. You will identify Tsunami when you will notice bubbles and big waves in the sea. It is a Japanese word that signifies harbor wave. These aren’t like those gentle waves that you surf on. Waves can be 100 feet high at the time of the Tsunami.
You must have heard about the Hurricane or Cyclone. It is also known as a tornado in some parts of the world. Whatever name you are familiar with, each of these names indicates the same disaster. Do you know how they occur?
The cloud of a large storm turns into a spiral with continuous spin and touches the ground from the sky; it is called Hurricane in the Atlantic and Northern Pacific. If the same thing happens in the northwestern part of the Pacific, then it is called Typhoon. But in the southwestern Pacific and the Indian Ocean, this similar storm is known as Cyclone.
Overflow of river water due to excessive rainfall or melting iceberg tends to flood. This is a threatening disaster for the people of low lands.
Landslide is another common phenomenon for people who live nearby a river or in hilly areas. This disaster also occurs because of immoderate rainfall, erosion, etc. This can sometimes be foretold at the monsoon.
Humans are helpless in front of nature. The reasons behind natural disasters are giving us a clear idea about each adverse event.
