Fascinating Fact:

In some coastal regions, undersea earthquakes can trigger tsunamis, which are large, powerful waves that can travel across entire ocean basins.

In GCSE Geography, pupils learn that earthquakes happen when stress builds up along faults and plate boundaries and is suddenly released. The shaking can damage buildings, cut off services and affect people’s lives in many ways, especially in densely populated or less prepared regions. Case studies often compare impacts in richer and poorer countries, as well as short-term responses and long-term management strategies.

Key Terms

Earthquake: A sudden shaking of the Earth’s surface caused by movement along a fault or plate boundary in the crust.
Focus (hypocentre): The point inside the Earth where the rocks first break and seismic waves are released.
Epicentre: The point on the Earth’s surface directly above the focus, where shaking is often felt most strongly.

Frequently Asked Questions (Click to see answers)

What causes earthquakes in GCSE Geography?

In GCSE Geography, earthquakes are explained as the result of plates moving past, towards or away from each other. When stress along faults suddenly releases, energy travels out as seismic waves and the ground shakes.

Where do most earthquakes happen in the world?

Most earthquakes occur along plate boundaries, such as the Pacific Ring of Fire. These are zones where plates collide, slide past or move apart, creating frequent movement and therefore frequent seismic activity.

How are earthquakes measured and recorded?

Earthquakes are recorded by seismometers that track ground movement. Their strength can be described using magnitude scales, such as the moment magnitude scale, which measures the energy released at the focus.

Geography Quiz - Earthquakes (Answers)

Where do earthquakes mainly occur?

[x]	At the boundaries between plates
[ ]	At the centre of plates
[ ]	Under the sea
[ ]	At the North and South Poles

They are mainly caused by plates moving against each other

On the following list, where is the deepest earthquake likely to occur?

[ ]	In the UK
[ ]	Somewhere along the San Andreas fault
[x]	The west coast of Peru
[ ]	Impossible to say, the depth of an earthquake is random

You should be aware of the main examples of the different types of plate boundary. You should also know that deep earthquakes occur at destructive plate boundaries. The west coast of Peru is where you find a destructive plate boundary

The movement of the Earth's plates past one-another is ...

[ ]	smooth
[ ]	completely predictable
[x]	jerky
[ ]	not known

There is a lot of friction between the rocks of the plates so they don't move smoothly past each other. This movement is unpredictable which is why earthquake forecasting is so difficult

Japan suffers from large earthquakes because ...

[ ]	it is a small country
[ ]	it is made up from several islands
[ ]	it is split down the middle by a constructive plate boundary
[x]	it is right next to a destructive plate boundary

The Pacific plate is being destroyed under Japan

Which of the following is not a reason why there is greater loss of life in a LEDC than a MEDC from an earthquake measuring 8 on the Richter scale?

[ ]	The rescue services are less well equipped
[x]	Communications are better
[ ]	Water supplies are cut
[ ]	Buildings are weaker

There are many reasons why populations in LEDCs or less developed regions of MEDCs are hit harder - it usually comes down to a lack of money

When compared with a LEDC, during a large earthquake, the buildings in a city of a MEDC ...

[ ]	will all collapse
[ ]	will burst into flame
[x]	are less likely to be damaged
[ ]	are more likely to suffer damage

MEDCs can afford to build earthquake resistant buildings

Which one of the following explains why we have small earthquakes in Britain?

[x]	They are caused by small movements of old faults in the rocks
[ ]	Britain is directly on a destructive plate boundary
[ ]	There is a conservative plate boundary that runs from north to south down the middle of Britain
[ ]	Britain is an island

Even though the faults were made millions of years in the past, the rocks on either side can still move a little, creating small earthquakes that are sometimes called earth tremors

The cause of an earthquake is ...

[ ]	hot magma from the mantle moving upwards through the crust
[ ]	water exploding because of the heat deep in the Earth's crust
[ ]	shrinkage of the Earth
[x]	the release of strain that has built up in rocks at a plate boundary

There is a huge amount of friction between the plates which stops them moving smoothly
