1.1 What happens during an earthquake?
Earthquakes shake the ground surface, can cause buildings to collapse, disrupt transport and services, and can cause fires. They can trigger landslides and tsunami – in short, earthquakes can be very destructive. In this unit you will look at why, where and what happens when they occur and also at how earthquakes are assessed qualitatively and quantitatively.
