Preparedness Measures
1.Land use regulations2.Infrastructure3.Emergency drills4.Earthquake and tsunami
monitoring and warning systems
Land use regulations• Stipulate the use of certain plots of
land.• Planning to move residential / heavy
industries away from high risk zones.• California – laws against building on
fault lines.• Japan – restrict against building on
lowland areas (tsunami risk)
Infrastructure
• Buildings that have technology to withstand earthquakes.• Need not be high-tech.–Japanese / Indonesian bamboo homes
that flex• Can be very high-tech–Taipei 101 building with in-built
pendulum to counter the shaking
Taipei 101
Emergency drills
• General population is taught and made to practice emergency drills• Households are taught to prepare
emergency bags• Education and practice to ensure
minimal panic when the event occurs.
Earthquake monitoring and warning systems
• Seismic activity can be measured with sensors that detect the waves.• Duration between detection and
arrival of earthquakes is small.• Potential window of opportunity for
people to evacuate.
Let’s take a look at potential questions
1. With modern technology, it is possible to prepare for an impending earthquake or tsunami. With the aid of examples, explain how this can be done. [4m]
2. Earthquake preparedness can save lives of children in school. Explain how this is done in a earthquake prone country. [4m]
3. Land use regulations can be used to reduce the social and economic impact of an earthquake. Explain how this is so. [4m]
