Mitigation Strategies Flashcards
What are the 3 mitigation strategies?
Early Warning system, Building design and Education
What is seismometers?
The tool used to measure the magnitude of an earthquake
What is a limitation of seismometers?
It only responds once the earthquake has happened
What is mitigation?
Reducing the severity of an impact and the seriousness or painfulness of an event.
What is an advantage of early warning system?
In Japan, a 60-second message is sent out and trains, production lines are stopped to reduce damage.
What is a disadvantage of early warning system?
It may be difficult to give accurate information to everybody in a text message
What is an advantage of building design?
Earthquake proof buildings protect people from future earthquake hazards.
What is a disadvantage of building design?
It is not possible to build earthquake proof buildings in every country in the world.
What is an advantage of education?
In Japan, people annually celebrate ‘National Earthquake Awareness Day’ to practice evacuations so people are educated on what to do.
What is a disadvantage of education?
Research from New Zealand suggests that multiple training sessions are needed for the effective preperation of families at home
What are radon gas emissions?
Gas is sometimes released by seismic stress before rock fractures
What is a limitation of radon gas emissions?
- It could only happen sometimes
- Wastes resources
What is animal behaviour?
Certain animals can sense vibrations in the earth before humans can
What is a limitation of animal behaviour?
Animals can respond to anything and they can’t tell us if they notice something
