how much energy is released during an earthquake, often measured in Mw (moment magnitude)

where the earthquake is first felt, the point on the surface directly above the focus

the point underground where the tectonic plates first break or slip

The effects of earthquakes

Geography

This unit teaches pupils about the physical processes that lead to tectonic hazards and investigates the geographical pattern of hazards across the world. Pupils will also learn how tectonic hazards affect people in different places and how people seek to manage hazards.
