how are earthquakes managed

• HIC = better - earthquakes proof buildings, Japan
• Earthquake proof buildings

  • Rolling weights on roofs
  • identification numbers for helicopters to identify which buildings are damages and which are not
  • shutters come down automatically - prevents glass shattering on those below
  • reinforced lift shafts
  • safe open areas for people to gather
  • lattice work steal cage to stabilise buildings
  • rubber shock absorbers between foundations and building above grounds
  • lattice work steel foundations into the bedrock
• LIC = not withstand
• LIC buildings

  • thatched roof likely to collapse during earthquake
  • area is cluttered so not safe for people to gather when they escape
  • materials aren't designed to withstand significant pressure
  • foundations susceptible to liquefaction which will cause building to collapse
