• Earthquake disaster planning


  • Prevention is key
• Before an earthquake


  1. Know earthquake hazards in your area

  2. Follow structural design and engineering practices when constructing buildings

  3. Evaluate structural soundness of buildings

  4. Prepare homes, workplaces, schools

  5. Strap or vault heavy furniture, cabinets to walls

  6. Check stability of hanging objects

  7. Store breakable, harmful, flammable items properly
