Chapter 2 : Living with tectonic
hazards
Gateway 3 :
Responses to earthquakes

2. Preparedness Measures
1.Land use regulations
2.Infrastructure
3.Emergency drills
4.Earthquake and tsunami
monitoring and warning
systems

3. 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)

4. Would we build cities on faultlines?

5. 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

6. Low Tech Infrastructure

7. Taipei 101

8. 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.

9. Emergency Drills

10. Emergency Drills

11. 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.

12. Earthquake monitoring

13. Tsunami monitoring

14. 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]

15. Homework
“Landuse regulation is the most
important factor when planning to
reduce the impact of an
earthquake on mankind.” How far
do you agree with this statement?
