Mount Pinatubo eruption, 1991

A natural disaster is the consequence of the combination of a natural hazard (a physical event like a volcanic eruption, typhoon, tropical cyclone, tornado an earthquake, a landslide or a tsunami) and human activities.

Only if humans are there where the hazard happens and if they have no sufficient emergency management, there will be human losses. Therefore one can say: "disasters occur when hazards meet vulnerability".[1] A natural hazard will therefore have no natural disaster as a result in areas without vulnerability, that means if for example a strong earthquake is in uninhabited areas.

International Red Cross and Red Crescent Movement is established to do help at emergency including natural disaster by Geneva Conventions, and Article 11 of the Convention on the Rights of Persons with Disabilities also defines such help by international law both humanitarian and human rights.
