The impact is the damage which happens as a result of the earthquake. The impacts of an earthquake can vary depending on:
- The size of the earthquake on the Richter scale - the higher it is on the scale, the more destruction it causes.
- Level of development - whether it occurs in a rich or a poor country. Richer countries will be more likely to be able to predict, and attempt to protect and prepare themselves from the effects of an earthquake.
- The depth of the focus - if it’s shallow it can be more destructive.
- The distance from epicentre - the effects of an earthquake are more severe at its centre.
- Population density - the more people living in an area, the more likely it is to be more deaths and casualties.
- The time of day - whether people are in their homes, at work or travelling.
We can classify the effects of an earthquake into the following categories:
- primary effects - things that happen immediately as a result of an earthquake
- secondary effects - happen in the hours, days and weeks after the initial earthquake
Responses are how countries react to an earthquake. They are categorised as follows:
- Short-term or immediate - a response in the hours, days and weeks immediately after an earthquake or disaster has happened. Short-term responses mainly involve search and rescue and helping the injured.
- Long-term - responses that go on for months and years after an earthquake or disaster. They can involve rebuilding destroyed houses, schools, hospitals, etc. They also involve kick-starting the local economy.
