3.6 Reducing Earthquake Damage There are a number of ways that we can try to reduce the damage
caused by earthquakes.
1. Predicting when an earthquake might occur: Scientists study historical records of when earthquakes have occurred at different plate boundaries. They can then predict when another earthquake may occur.
2. Planning for earthquakes: Using maps of areas most at risk of earthquakes, planners can make decisions regarding areas unsuitable for the construction of certain buildings. For example, they would not wish to build a hospital in an area that is at high risk of an earthquake.
3. Construction of earthquake-safe buildings: Buildings and bridges can be designed and built to resist the shaking that occurs during an earthquake. An example of an earthquake-proof building is the Torre Mayor skyscraper in Mexico City.
Computer-controlled weights on roof to reduce movement
Steel frames that can sway during earth movements
Automatic window shutters to prevent falling glass
Open areas where people can assemble if evacuated
‘Birdcage’ interlocking steel frame
Outer panels flexibly attached to steel structure
Fire-resistant building materials
Roads to provide quick access for emergency services
Having examined Being Creative: the diagram on the left,
redesign your school or home to withstand the effects of a magnitude 8 earthquake. Your answer should include sketches of the new building(s) and a written explanation of the measures taken to withstand the shaking that takes place during the earthquake.
