KQ3 Strategies to mitigate earthquakes and tsunamis

What is land use regulations?

• A set of rules to restrict development in tsunami prone areas only.

• A set of rules to restrict development in earthquake prone areas only.

• A set of rules to restrict development in areas of high risk of soil liquefaction during an earthquake and tsunami prone areas.

Land use regulations are very cost-effective.

• True

• False

Taipei 101 is an example of...

• Land use regulation

• Earthquake monitoring system

• Effective building design

• Emergency drill

Infrastructure - effective building design makes use of advanced engineering to withstand the vibrations associated with an earthquake.

• True

• False

All countries with better infrastructure designed to withstand earthquake vibrations will have zero fatalities.

• True

• False

Tick the boxes that describes 'Emergency drills'.

• A form of preparedness measure where people practice steps to take when an earthquake occurs

• Creates awareness and reduces levels of panic and irrational behaviour during the earthquake.

• People may take part in emergency drills by moving to safe locations, listening to instructions given by trained personnel and practicing first aid.

• The emergency drills are based on scale and magnitude of past events and therefore emergency scenario might not be realistic

The photograph shows an example of...

• Infrastructure

• Emergency Drill

• Land use regulations

• Earthquake and tsunami monitoring systems

Earthquake and tsunami monitoring systems are the same.

• True

• False

The following statements are true about earthquake monitoring and warning systems below:

• monitor the frequency of vibrations and detect possible developments of an earthquake.

• provides an estimation of the frequency and magnitude of earthquakes at particular fault lines

• Noise, lightning or device failure may interfere with the seismograph and result in false warning being given

• It is difficult to give accurate warnings when multiple earthquakes occur close to each other.
