managing seismic events Flashcards
what are the 3 p’s?
prediction
prevention
preparation/protection
how can an earthquake be predicted?
- identified through plate tectonics
- monitoring ground water levels, release of radon levels and unusual animal behaviour
- mapped based on geological information
which gas can help with the prediction of earthquakes?
radon
can earthquakes be predicted hours before?
it is questionable, very difficult to predict an earthquake
is possible to prevent an earthquake?
thought to be near impossible
laser beams can be used to track plate movement
seisometers to detect small tremors
what are some theories that deal with the prevention of earthquakes?
lubricating the plates so that they slide past rather than getting caught, using oil or water
how can earthquakes be prepared for / protect people?
educate people about the risks
improve buildings structures
earthquake policies
what have the JMA installed and which country?
early warning system in japan
what are some examples of ways to create hazard resistant buildings?
- putting rubber shock absorbers in the foundations, allowing some movement in the building
- cross bracing, hold it together when it shakes
what are the other features needed to manage a hazard>
education aid tsunami protection fire prevention emergency services land use planning insurance
what are examples of education?
first aid kits given out
how can fire be prevented?
‘smart metres’ cut off gas when an earthquake of sufficient power occurs
