Concept of Disaster.pptx

  1. 1. Why is there a need to study Disaster Readiness and Risk Reduction?
  2. 2. DRRR 11 STEM/GAS
  3. 3. At the end of this lesson, the learners should be able to; Explain the meaning of disaster. (DRRR/12-Ia-b-1)
  4. 4. When does a natural event become a hazard? A natural event can be likened to a weak concrete fence that could collapse even with just a slight push. It does not pose a threat to anything or anybody if there is nothing or no one nearby. Once you park a car or stand right beside it, it becomes a hazard. The threat of damage, injury, and even death now exists.
  5. 5. When does a NATURAL EVENT become a HAZARD? A natural event can be likened to a weak concrete fence that could collapse even with just a slight push. It does not pose a threat to anything or anybody if there is nothing or no one nearby. Once you park a car or stand right beside it, it becomes a hazard. The threat of damage, injury, and even death now exists.
  6. 6. When does a HAZARD becomes a DISASTER? A disaster happens when the probable destructive agent, the hazard, hits a vulnerable populated area. A natural event like the volcanic eruption or tsunami which hits an uninhabited area does not qualify as a disaster.
  7. 7. The transformation of natural event into a disaster. A natural event such as a tsunami becomes a hazard if it poses a threat to people. A magnitude 6.5 earthquake is usually strong enough to generate tsunamis that could be destructive to nearby coastal areas. The tsunami waves that are about to hit a beach area with people, animals, trees and houses are considered as a hazard. After the tsunami hits the populated area, it is no longer a hazard but a disaster with victims and destruction or damage all over the place.
  8. 8.  A typhoon or storm surge affecting Leyte  A typhoon passing over a remote and unpopulated island.  A flood in a rural area which floods the roads but does not affect any houses.  A volcano erupting in isolation in the middle of the Pacific Ocean  An avalanche in a ski resort  An avalanche high on the mountain and slopes remote from any settlement  A tsunami wave 5m high off coast of Japan  An earthquake in Kashmir, Northern Pakistan  A drought in Australia’s Outback (a vast, remote, arid interior of Australia)  A landslide in a favela (slum area) in Rio De Janeiro.
  9. 9. 1. Name at least 3 natural phenomena that your community considers as hazard. Explain why they are considered hazard. 2. Explain what is meant by ‘Buildings kill people, not earthquake’. 3. Explain how a seemingly harmless normal river flows in the middle of a rapidly developing city, can later cause a disaster.
