| A is the consequence of when a potential natural hazard becomesa physical event (e.g. volcanic eruption, earthquake, landslide) and thisinteracts with human activities. Human vulnerability, caused by the lack ofplanning, lack of appropriate emergency management or the event beingunexpected, leads to financial, structural, and human losses. The resulting lossdepends on the capacity of the population to support or resist the disaster, their resilience.[1] This understanding is concentrated in the formulation: "disasters occur when hazards meet vulnerability".[2] A natural hazard willhence never result in a natural disaster in areas without vulnerability, e.g. strong earthquakes in uninhabited areas. The term natural has consequently beendisputed because the events simply are not hazards or disasters without humaninvolvement. | |
