What are earthquakes:
An earthquake is the shaking of the Earth's surface caused by a sudden release of energy in the Earth's crust. This energy release usually happens because of the movement of tectonic plates, which are large sections of the Earth's crust that float on the semi-fluid layer beneath called the mantle.
The characteristic's of earthquakes:
• The location of the epicentre, because the closer to the epicentre the greater the damage.
• The time of the earthquake, because if the earthquake occurs during winter months or at night there is often a greater loss of life.
• The geology of the area, which determines whether liquefaction takes place.
• The severity of aftershocks, which can cause already damaged buildings to collapse.
