- Earthquakes
- Causes of Earthquakes
- Tectonics
- Tension at divergent boundaries
- Stretching of crust leads to plates slipping
- Shearing at conservative boundaries
- To plates sliding past each other building up friction
- Tension at divergent boundaries
- Tectonics
- Prediction
- Earthquake migration
- Quake locations can be predicted by following the fault line
- Successful predictions can be made to prevent casualites
- Detectors
- Radon gas in groundwater decreases
- All usually come before a quake
- Groundwater levels rise when ground swells
- All usually come before a quake
- Groundwater levels rise when ground swells
- Fore shocks measured carfeully
- All usually come before a quake
- All usually come before a quake
- Radon gas in groundwater decreases
- Tsunami Warning System
- Sensor measuring water pressure
- Transmits a signal to the sirens on the beach
- Earthquake migration
- Hazards
- Fires and Casualities
- Burst gas pipes can easily set fire
- Falling buildings can seriously injure people
- Liquefaction
- Ground water is brought to the surface
- Usually on sand or soil where the solid is weak
- Shaking
- Weakens infrastructue
- Causes most damage
- Flooding
- Tsunamis caused by earthquakes
- Fires and Casualities
- Preparation
- Infrastructure
- Earthquake proof buildings with deep foundations
- Warning System
- Sirens on beaches to warn tourists of tsunamis
- Education
- Raising awareness
- Educate people on what to do in an earthquake
- Infrastructure
- Causes of Earthquakes
