Prediction, protection and preparation
Prediction
Prediction involves using A machine that detects seismic waves caused by earthquakes. to monitor earth tremors. Experts know where earthquakes are likely to happen, however it's very difficult to predict when they will happen. Even looking at the timescale between earthquakes doesn't seem to work.
Protection
Many areas prone to earthquake hazards now use building codes. Any new building or adjustment to existing buildings must be built to strict guidelines that would protect people from future earthquake hazards. Protection involves constructing buildings so that they are safe to live in and will not collapse. Some examples of building improvements are:
- Rubber shock absorbers in the foundations to absorb the earth tremors.
- Steel frames that can sway during earth movements.
- Open areas outside of the buildings where people can assemble during an evacuation.
- Low cost methods, such as wire mesh To add a component or an upgrade to something that didn鈥檛 exist at the time it was made., are used in rural areas and developing countries. These are affordable and appropriate to the resources and people living there.
- Lightweight roofs and safety glass designed to reduce damage and injury.
Preparation
Hospitals, emergency services and residents practise for an earthquake in earthquake-prone countries. They have drills in all public buildings so that people know what to do in the event of an earthquake. This helps to reduce the impact and increases people's chance of survival.
