The point inside Earth’s crust where the earthquake starts is called the focus.

The epicentre is the point on Earth's surface directly above the focus of an earthquake.

Seismic waves are vibrations that travel through Earth generated by an earthquake or an explosion.

Magnitude is a measure of the size of the seismic waves generated by an earthquake.

Using digital maps to identify patterns of earthquakes around the world

This unit provides a foundation for 'Coasts: Diversity and change', which investigates very different physical processes and their impact on people and the environment.

This builds on 'Mountains and volcanoes: What, where and why?', extending and deepening pupils’ understanding of Earth processes, focusing on tectonic plates, earthquakes and their impact on people and the environment. 

This unit explores the causes and effects of earthquakes. Pupils learn where and why they occur, how they are measured, and what can be done to prepare for and respond to them. Case studies include Japan (2011) and Turkey (2023).
