For your glossary… • Vulnerability – refer to a person or group who are more susceptible (likely) to face attack. • Ricter scale – This is how the strength of earthquakes are measured • Magnitude – the amount of energy released by an earthquake • Aftershock – a shock which occurs after the main earthquake
Activity 1: Copy and complete 1. An earthquake occurs when t______ which has built up between two plates is r_______. 2. They usually occur along plate b_________. 3. A____________ are smaller shocks that follow the main earthquake. 4. The amount of energy released by an earthquake is called m_____________.

When two plates are sliding past each other, parts get locked and enormous tension builds up Epicentre is the centre of the earthquake on the surface Seismic waves spread out from the focus, like ripples on a pond.
