- Earthquakes occur on plate margins.
- As one plate rubs against the other, pressure builds up and when this pressure reaches its maximum it releases suddenly and causes an earthquake.
- Earthquakes can have disastrous effects but this is dependent on how rich the country is and how well it has prepared.
- Effects of an earthquake: gas pipes fracture causing fires, buildings collapse, sewage pipes broken - risk of disease.
