When Natural calamity occur

 The shaking or vibrating of the earth is referred to as an earthquake. There are many sizes of earthquakes. Some as a result are so weak that they are not observed. But some people are so powerful they have the ability to completely destroy cities. Ground disturbance can result from earthquakes. Additionally, the is capable of causing Tsunami, avalanches, and landslides. The majority of an earthquake's  nevertheless, is offshore.  These may lead to energy release. The earth's core is responsible for this release. Seismic waves are also produced when energy is released. Earthquakes are caused by the rupturing of geological faults. However, other occurrences like volcanic eruptions, landslides, and mine blasts might also be the cause  These are catastrophes with a radius of 50 to 100 kilometers. Disasters of this nature therefore do not generally do significant harm. Disasters that affect an area of between 100 and 500 kilometers are considered medium scale. Compared to a small scale catastrophe, these cause more harm. Furthermore, if they happen in colonial states, they may result in more harm. Large-scale disasters: These disasters affect more than 1000 km. The most serious environmental harm is caused by these. Additionally, if the severity is extreme, these catastrophes may even take over a whole nation. In the case of the dinosaurs, for example, a significant natural disaster was the cause of their extinction. It is possible to protect lives and property by providing clear predictions and warnings in an easily understandable format, as well as by instructing people on how to prepare for such threats before they become disasters. The focus is on reducing the likelihood of a disaster occurring; one dollar spent on preparedness can prevent seven dollars in economic losses caused by disasters, which represents a large return on investment.  WHO Members have committed to preventing new and reducing existing disaster risk through the implementation of a variety of integrated and inclusive measures that prevent and reduce hazard exposure and disaster vulnerability, as well as increase preparedness for response and recovery. A natural disaster is a risk or hazard that occurs naturally on Earth due to its natural processes and has disastrous economic, humanitarian, and environmental effects. It results in widespread loss of life and property. When a natural disaster strikes, so many people lose their lives, and for those who are left homeless after losing loved ones, life turns into a daily fight to survive. Natural calamities can take the form of avalanches, earthquakes, volcanic eruptions, landslides, floods, tsunamis, storms, blizzards, droughts, etc. Unimaginable destruction is caused by these catastrophes. Human fallibility and deficiency Natural disasters like earthquakes, cyclones, floods, and droughts have had a significant negative impact on India. The integration of a multifunctional, multidisciplinary, and sectoral strategy combining engineering, social, and financial processes is stressed in disaster management. India, sadly, has a poor track record when it comes to catastrophe management. Because they are a natural element of the environment in which we live, natural disasters cannot be avoided. To the best of our ability, however, we can take preventative actions at various societal levels to lessen the effects of these natural calamities on the populace and their possessions. Here, we give you further information on each of these characteristics in the four pieces that follow, which range in word count from 300 to 800.
