  4. 4. What is Earthquake?  The shaking of earth caused by waves moving on and below the earth's surface.  Earthquakes are the shaking, rolling or sudden shock of the earth’s surface.  A sudden slipping or movement of a portion of the Earth’s crust, followed by a series of vibrations. 4/20/2014 Earthquake and Risk Matigation 4

  7. 7. Plate Tectonics / Margins  Earthquake occurs at plate margins and at major fault lines.  But mostly on the conservative and destructive margins.  The two plates at a plate margin cannot move past each other easily. The two plates become locked. Friction causes pressure to build up. Suddenly, the pressure is released and the plates jolt into a new position. This causes seismic waves. The vibrations they cause are called an earthquake. Sunday, April 20, 2014 Earthquake and Risk Matigation 8

  11. 11. Human Causes  Man has a way of affecting nature, and so causing his own difficulties.  COAL MINING: There is increased stress on the remaining rocks, making earthquakes more likely to occur.  BUILDING DAMS: The weight of the water when the valley behind the dam is filled causes increase pressure on the earth crust. 4/20/2014 Earthquake and Risk Matigation 12
  12. 12.  Focus is the point at which the rock moves. The seismic waves start at the focus.  Epicentre is directly above the focus on the Earth’s surface. 4/20/2014 Earthquake and Risk Matigation 13 A B Focus Epicentre seismic waves

  15. 15. Earthquake Mitigation  Mitigation is: “any action taken to reduce or eliminate the long-term risk to human life and property from natural hazards”.  Transferring the responsibility of the risk by getting insurance.  Also educating the public and raising awareness of earthquake risks...!!! 4/20/2014 Earthquake and Risk Matigation 16

  18. 18. 4/20/2014 Earthquake and Risk Matigation 19
  19. 19. PERONAL LEVEL: Before • Put together an emergency kit – flashlight, first aid kit, radio, drinking water, blankets. • Develop a family communication plan – identify a relative living at least 100 miles away; everyone can call to “check in” to tell family you’re safe. • Make sure all heavy or breakable items are on lower shelves. • Know how to turn off utilities. 4/20/2014 Earthquake and Risk Matigation 20
  20. 20. PRESONAL LEVEL: During 1. DROP to the ground. 2. COVER yourself under a sturdy table or desk, and cover your face and head with your arms. 3. HOLD ON to something sturdy until the shaking stops. 4/20/2014 Earthquake and Risk Matigation 21

  22. 22. Con’t  If you’re driving, pull off the road, away from buildings and utility poles, and stay in your car.  If you’re outside, drop to the ground, away from large objects, and cover your face and head with your arms. 4/20/2014 Earthquake and Risk Matigation 23
  23. 23. PERSONAL LEVEL: After  Find your family; check for injuries  If you smell gas or hear a hissing sound, go outside – shut off gas valve  Be careful to avoid live power lines and broken glass  Listen to news for latest emergency information  Be ready for aftershocks! 4/20/2014 Earthquake and Risk Matigation 24
  24. 24. GOVERNMENT LEVEL  Provide a building standard for contractors to allow for sound housing.  Educating the population on earthquakes as a hazard.  Putting in place safety regulations such as a standard for the number of emergency exits.  Providing service teams for search and rescue operations after the earthquake. 4/20/2014 Earthquake and Risk Matigation 25

  31. 31. FICTION AND FACTS ABOUT EARTHQUAKE  Fiction: Earthquakes usually happen in the morning.  Fact: Earthquakes happen in both the day and the night. There is no pattern.  Fiction: There is such a thing as "earthquake weather.“  Fact: There is no connection between earthquakes and weather. Remember, earthquakes happen deep in the earth, far away from the weather!  . 4/20/2014 Earthquake and Risk Matigation 32
  32. 32. Con’t  Fiction: Earthquakes are on the increase.  Fact: It may seem like we’re having more earthquakes because there are more reporting stations, but the truth is we’re not.   Fiction: We can prevent earthquakes from happening.  Fact: No. You can protect yourself by doing things to secure buildings, like your home, but earthquakes can’t be prevented -- or predicted 4/20/2014 Earthquake and Risk Matigation 33
