Introduction
It is correctly said that Nature can create and nature can destroy. Nature possesses equal powers of creation and destruction.
A natural disaster is an adverse natural event that causes great damage to life and property on the earth.
These events are quite damaging to the environment and also may destroy the life of living beings on Earth.
Primary natural disasters
Earthquakes, Landslides, Cyclones, tsunamis, Volcanic eruptions, Avalanches, Draughts and Floods are some primary natural disasters.
Every type of this has great potential for the destruction of lives and the environment. The strength of a natural disaster decides the quantity of destruction.
The strength of a natural disaster is divided into three types. The first ones cover a diameter of 50 to 100 km and make lower damage. The second type covers a diameter of 100 to 500 km and is more destructive than the first one.
The third is a large-scale natural disaster that covers more than 1000 km and it is the most destructive type of natural disaster.
How do natural disasters occur
A natural disaster occurs because of many reasons. An earthquake occurs because of the release of energy from the earth’s centre.
Landslide occurs because of gravitational forces. Some natural disasters occur because of internal geological activities.
Some disasters are a result of one natural disaster. For example, earthquakes and volcanic eruptions can cause landslides and avalanches.
But it is to be noted that many natural disasters are triggered due to human activities. Hence, we need to regulate human activities to save the environment and prevent climate change.
Draught is a condition of low groundwater levels and it is considered one of the human-generated natural disasters.
Soil erosion because of deforestation is also a cause of many natural calamities like landslides and floods.
There is a need to spread awareness to conserve natural resources for fewer natural disasters.
Conclusion
In conclusion, various natural disasters have been confirmed to be fatal. People must take sensible measures in the time of emergencies that will help them get out of it.
Government and National Disaster Management Authority should launch some programmes to make people prepared for any type of natural disaster.

Introduction
A Natural disaster is an unforeseen natural event that causes massive harm to the world. Many types of natural disasters damage the environment and many lives of living beings.
Some natural disasters are now predictable before their occurrence but prevention of most natural phenomena is next to impossible. But we can reduce the quantity of damage by an upcoming natural disaster.
Nature holds a super destructive potential that can not be finely estimated. Earthquakes, Landslides, Cyclones, tsunamis, Volcanic eruptions, Avalanches, Draughts and Floods are some primary natural disasters. The last two are considered purely man-made disasters.
Types of natural disasters
There are various types of natural disasters. We will discuss the chief ones.
Earthquake: Earth is a type of natural disaster in which the earth start to shake or vibrate itself. The harm by an earthquake depends upon the strength of the earthquake. Some weak earthquakes bring no harm while stronger ones can destroy an entire city.
Landslides: Landslides generally occur in mountains or hilly areas. The moving of big slabs of rocks or debris down a slope is referred to as landslides. It is unpredictable and so it can damage man-made things.
Cyclones and Tsunamis: A cyclone is a large-scale air volume that rotates around a powerful centre of low atmospheric pressure. The air moves in a spiral track that goes inwards. Cyclones are of many types and strengths. A Tsunami is formed with very powerful waves than cyclones.
Avalanches: Avalanches are just like landslides. It is an incident of a huge amount of snow down falling on the slope. This is also an unpredictable event and can damage at a notable level.
Floods and Droughts: A flood is an overflow of water that submerges usually dry land. They can also come on quickly or build gradually. Drought is caused by drier-than-usual conditions that can lead to low groundwater levels.
Causes of natural disasters
We can distinguish the causes of natural disasters between two buckets. The first is natural processes and the second is human activities. Gravitational pull, Energy released from the centre of the earth, atmospheric changes, and internal geological activities are some of the natural causes of natural disasters.
Furthermore, one disaster can invite some other ones. For example, when an earthquake takes place, it can cause landslides, avalanches, cyclones and floods etc.
Apart from natural causes, human activities also cause some natural disasters. Soil erosion due to deforestation causes landslides in hilly areas. Pulling out water from the ground at high levels causes draughts. Mine blasts can cause different types of natural calamities.
Effects of natural disasters
A natural disaster can leave a huge quantity of damage and destruction. It affects living beings and the environment. Sometimes it can be a reason for thousands of deaths and billions of economical value. A natural disaster is classified into three levels.
The first level of disasters causes low-level damage and covers a diameter of 50 to 100 km. Medium-scale natural disaster extends between 100 to 500 km and causes more damage than that on a lower scale.
The third one is the most dangerous and extends more than 1000 km in diameter. It is called a large-scale natural disaster. It can damage the whole country. A large-scale disaster was the reason behind the extinction of dinosaurs.
Final Words (Conclusion)
To sum it up, nature is equipped with both the powers- to create and to destroy. A natural disaster is an adverse event of nature that can cause massive destruction. It can also take many lives at once and a huge loss of monetary value.
I hope it will be possible soon to predict the occurrence of natural calamities before time so that we can help the masses to escape from a natural disaster.
