Earthquake Mitigation Measures (Preparedness measures)

Which of these are earthquake resistant building strategies?

Select all that apply.

• Sheer walls

• Cross braces

• Reinforced concrete

• Damping device

• Base isolation

Answer explanation

Sheer walls : SPELLING ERROR!

It should be SHEAR walls!

A wide base makes the building more sturdy because ...

• tremors are distributed over a wider area, increasing the amount of shaking.

• tremors are distributed over a wider area, reducing the amount of shaking.

• the stronger material decreases likelihood of the building collapsing.

• people can evacuate safely.

True or false?

People are most likely to be injured in an earthquake due to the collapse of buildings.

• True

• False

Which of these are earthquake preparedness measures?

Select the box with preparedness measures ONLY.

• Emergency drills, monitoring and warning system, rebuilding of infrastructure

• Search and rescue, emergency drills, provision of health care

• Land use infrastructure, emergency food and medical supplies

• Emergency drills, monitoring and warning system, land use regulation

Which of these are responses to earthquakes?

Select the box with responses AFTER earthquakes take place ONLY.

• Emergency drills, search and rescue, rebuilding of infrastructure

• Search and rescue, emergency food and medical supplies, provision of health care

• Land use infrastructure, emergency food and medical supplies, provision of health care

• Building infrastructure, monitoring and warning system, land use regulation

Choose the strategy that the following description represents:

Rules implemented to restrict developments in certain areas demarcated as highly unsafe (may be close to a plate boundary or near unconsolidated soil).

• Earthquake warning system

• Emergency drills

• Strengthening building infrastructure

• Land use regulation

Choose the strategy that the following description represents:

Alarms that go off once earthquake sensors detect possible developments of an earthquake.

• Earthquake warning system

• Emergency drills

• Strengthening building infrastructure

• Land use regulation

Choose the strategy that the following description represents:

Ensuring people know the quickest evacuation route to a safe location. This avoids mass panic and saves lives in the event of the quake.

• Earthquake warning system

• Emergency drills

• Effective building design

• Land use regulation

Choose the strategy that the following description represents:

Cutting off power supply using trip switches to ensure all electrical points are switched off once an earthquake is detected. This prevents secondary impacts of earthquakes like fires from breaking out.

• Earthquake warning system

• Emergency drills

• Effective building design

• Land use regulation

Choose the strategy that the following description represents:

Monitoring seismic activity and sea level height to detect if an earthquake has led to a tsunami.

• Tsunami monitoring system

• Tsunami warning system

• Earthquake monitoring system

• Earthquake monitoring system
