Answer:
1. Transportation
2. Buildings
3. Hazardous Materials
Explanation:
1. Earthquakes sometimes threaten the safety of people in transit, with only airborne vehicles remaining completely safe. Adaptations included compressing the earth surrounding a tunnel and reinforcing some transit buildings and raised tracks. The Golden Gate Bridge, Highway and Transportation District indicates that after an earthquake, authorities improved the Golden Gate Bridge by installing additional bracing, boosting the strength of bridge foundations and adding expansion joints, among other adaptations.
2.When earthquakes occur, structural adaptations do much to prevent the damage or destruction of buildings. Encarta indicates that builders reinforce some structures against earthquakes with bracing. Relatively small buildings made of wood prove less susceptible than those constructed of rock-like materials such as concrete. It's possible to enact structural adaptations during construction or to reinforce old buildings. Some newer structures in California and Japan feature a flexible design which causes them to sway during earthquakes rather than collapse, according to Public Radio International.
3. In regions prone to earthquakes, it also is important to adaptations the storage and transport of toxic or highly flammable materials. Keeping hazardous substances close to the floor helps prevent their release during earthquakes, according to the U.S. Geological Survey. The less distance they have to fall, the less chance that the containers will break open. The USGS also recommends using flexible indoor natural gas lines rather than rigid pipes, which may break in earthquakes and start fires.
