Earthwaukes Management Flashcards
Monitoring method - laser reflector
Monitors small movements along fault
Monitoring method creep meter
Monitors small movements along fault
Monitoring method - strain meter
Measured changes of stress in rocks
Monitoring method - well levels and groundwater measurements
Monitors ground water movement and height of water table which can change just before an earthquake
Radon gas meter
Levels of radon gas dissolved in water can increase before earthquake
Seismometer
Recording small foreshocks to predict quake
Quick facts on earthquake prediction
No accurate prediction yet
Predictions must cover date time and size
Unofficial predictions end up on social media and often no earthquake follows
How can you modify earthquakes event ?
not possible yet
How can you decrease human vulnerability ( buildings )
Building codes such as aseismic buildings in japan and USA
Although difficult to retrofit old buildings
Cost are prohibitive except for most important public buildings
In many developing countries it may be difficult to before LCS the codes due to lack of political will it money
How can you decrease human vulnerability except buildings
Education and drills
Hazard mapping for areas prone to liquefaction
Increasing use of smart technology to send out warnings
