Effects and responses of earthquakes
The effect of an earthquake is the damage which happens as a result of the earthquake. The effects 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 can cause.
- Level of development - whether it occurs in a rich or a poor country. Richer countries will be more likely to be able to predict, protect and prepare themselves from the effects of an earthquake.
- The depth of the focus - if it's shallow, it can be more destructive.
- 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 that more deaths and casualties may arise.
- The time of day - whether people are in their homes, 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 - things that 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 days and weeks immediately after a 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 a disaster. It involves rebuilding destroyed houses, schools, hospitals, etc. It also involves kick-starting the local economy.
