Tectonic hazards Flashcards
How are earthquakes monitored?
Foreshocks using seismometers and GPS.
Radon using radon detection devices.
How are volcanoes monitored?
Changes in shape of ground/volcano using tiltmeters.
Radon and sulphur gas using gas trapping bottles.
Earthquakes near magma chambers using seismometers.
Ground surface and river temps suing thermal heat sensors.
How are earthquakes predicted?
It is extremely difficult to predict the time, location, date and exact location of an earthquake.
Protection against earthquakes.
Building and transport infrastructure. retrofitting for example, using rubber shock absorbers. Very expensive.
Sea walls in case of tsunamis.
Planning for earthquakes.
Practice drills.
Preparing emergency supplies and location of evacuation centres.
Securing objects/furniture.
How are volcanic eruptions predicted?
Easier to predict than earthquakes because they give advance warning signals before erupting.
Protection against volcanic eruptions.
Buildings cannot be designed to completely protect against eruption impacts.
Evacuation instructed by authorities.
Planning for volcanic eruptions.
Evacuation
Exclusion zones
Education to know what to do
First-aid training
