Central point of the earthquake on the Earth’s surface.
Hypocentre:
Location in the Earth where the stress has been released.
Slide 18 - Tekstslide
Effects of an earthquake
Aftershocks
: Tremors following the main earthquake.
Buildings and infrastructure (roads, cables, etc.) collapse.
Victims (injuries or even deaths).
Landslides
: Soil and rocks wiggle loose and slide down the hill.
Liquefaction
: The soil becomes liquid and cars and buildings sink into it.
Slide 19 - Tekstslide
A

caused by an earthquake damaged the road.
Slide 20 - Tekstslide
Soil

after an earthquake in New Zealand.
Slide 21 - Tekstslide
Tsunami
Tsunami
= A giant wave caused by an earthquake underneath the ocean.
When the waves reach shallower water:
Their height can increase by several metres.
The shallow water slows the wave.
The waves get closer together.
