Monitoring, Prediction, Mitigation and Planning Flashcards
Earthquakes and Volcanoes
hazard
What is monitoring?
When measurement is taken to calculate the increasing activity in a hazardous area.
Can we monitor earthquake?
No, it is only for volcanoes
List me 4 methods of monitoring for volcanoes
- Remote sensing
- Gas measurements
- Ground deformation
- Water pressure
Ways to monitor volcanoes
Water pressure
Measuring the increase in ground water pressure
Ways to monitor volcanoes
Ground deformation
Using laser beams and mercury tilt meters to record changes in the shape of the land.
Ways to monitor volcanoes
Remote Sensing
detecting heat changes in the crust and changes in the shape of the land.
Hazard
What is Prediction
When information gathered from monitoring is used to make educate guess about when hazard will occur
Prediction for volcano?
It is possible to predict when volcano will occur.
Prediction for earthquakes?
Accurate predictions are not possible for earthquakes
Give me one prediction methods.
Probability mapping
What is probability mapping?
Using historical event frequency information to determine the chance of another event occuring in a given amount of time
hazard
What is mitigation
When we take steps to reduce the severity of a hazard.
List 2 ways of mitigation
- Diversion tactics (volcanoes)
- Emergency drills (both)
Ways of mitigation
Diversion tactics
Explosives, concrete blockades or channels might be dug to divert flows of materials.
Ways of mitigation
Emergency drills
practicing what to do in the event of a disaster to ensure people respond in safest way.
