world's natural disasters

The effects of a disaster can be amplified due to poor planning of human settlements, lack of safety measures, emergency plans and warning systems and man becomes a bit fuzzy.

To the institutional capacity to reduce disaster risk group, they can trigger other events that will reduce the chance of surviving it because of gaps in planning and security measures. A classic example is earthquakes, collapsing buildings and houses, leaving people trapped in the rubble and broken gas pipes can ignite and burn casualties under the rubble.

Human activity in areas with high probability of natural disasters is known as high risk. High-risk areas without instrumentation and appropriate measures to respond to natural disasters or reduce their negative effects are known as areas of high vulnerability.

Natural disasters

Natural phenomena such as rain, earthquakes, hurricanes or wind, they become disasters when they exceed a limit of normal (threshold, in English), usually measured through a parameter. This varies depending on the type of phenomenon Seismic Moment Magnitude (Mw) (Richter scale for earthquakes, Saphir-Simpson scale for hurricanes, etc.).

Disasters are caused by human activities that alter the normal environment. Some of these are: environmental pollution, erroneous and irrational exploitation of renewable natural resources such as forests and soil and non-renewable such as minerals, building houses and buildings in high risk areas.

disasters of humanity

The wind, waves and all the natural dynamics show the complex interplay between the lithosphere, hydrosphere, atmosphere and biosphere. Much of this dynamic are to humans almost imperceptible, such as erosion and sedimentation caused by wind, rivers, glaciers, and so on. However, there are times when behavior becomes violent natural elements, such as earthquakes and volcanic eruptions, putting at risk the companies, assets and activities.

An earthquake, hurricane or other extreme event of nature becomes a disaster or disaster when loss of life or economic causes. That is, is called "Natural Disaster"only when the social or economic problem is triggered by a freak of nature. Golden Loe says "... a potential danger becomes a disaster if it occurs where people live. "
