Natural disasters are catastrophic events caused by natural processes of the Earth. They can lead to significant destruction and loss of life. Examples include earthquakes, which occur when there is a sudden release of energy in the Earth's crust, and tsunamis, which are large ocean waves typically caused by underwater earthquakes or volcanic eruptions. These events can have devastating effects on communities, infrastructure, and the environment. Preparedness and response strategies are crucial for minimizing damage and ensuring safety. Understanding the science behind these disasters helps in developing better warning systems and resilience plans for affected areas.
