Explain the difference between a natural disaster and a national disaster.

Here's the differentiation between the concepts:

• Natural disaster: A natural disaster is a major adverse event resulting from natural processes of the Earth, such as floods, earthquakes, volcanic eruptions, hurricanes, and tsunamis. These events are not caused by human activity.

• National Disaster: A national disaster is a disaster (which can be natural or human-made) that is so severe in its magnitude or scope that it affects a significant portion of a country, requiring a coordinated national response and resources beyond what local or regional authorities can provide. It implies a declaration by the national government due to widespread impact.

The key difference lies in their origin and scope: a natural disaster is always caused by nature, while a national disaster refers to the scale and impact of any disaster (natural or otherwise) on a country, necessitating a national-level response.
