Every 30 seconds there is an earthquake somewhere in the world - including in Britain.
Maps can be investigated to locate major earthquake zones.
Earthquakes occur near the boundary of tectonic plates.

Earthquakes only occur at tectonic plate boundaries.

Earthquakes can occur anywhere in the world, but they are most commonly found at tectonic plate boundaries.

Tectonic plates - The huge pieces that Earth’s crust is broken into are known as tectonic plates.
Plate boundaries - The point where two tectonic plates meet is known as a plate boundary.
Mantle - The mantle is the layer between Earth’s outer core and crust. It is the largest layer of Earth and is mostly semi-molten lava.
