- Physical Effects of Earthquakes
- Ground movement
- Vibrations travel through the ground
- Larger amplitude waves = More damage
- Damage to structures
- Walls collapsing from bricks seperating along the mortar
- Floors seperating from wall causing them to "pancake"
- Bridges seperate from piers
- Pipes can seperate and leak
- Liquefaction
- Water seperates from solid particles in deposits like soil/sand
- Houses can end up flooded and cause damage
- Landslips
- Steep slope + high rainfall = Unstable after earthquake
- Loss of life from burial and also hamper rescue attempts
- Aftershocks
- Structures weakened by main quake can collapse through these
- Cause further damage and worse for rescue workers
- Tsunamis
- From bodily displacement of a large volume of water
- Speed of up to 700km/hr
- Sea drains away from shore-line before tsunami strikes
- Ground movement
