Earthquake is Natural Disaster

Natural disaster is defined as the effect of nature that is hazardous and affecting human activities. Earthquake is a sudden shaking of the earth. The vibrations vary in magnitude from mild to very serious and destructive. Earthquakes by themselves are rarely disastrous. It is usually the secondary events that trigger disasters, such as building collapse, fires and tsunamis.

The exact time and place when an Earthquake will occur normally cannot be predicted. Using historical and past data, seismic agencies around the world can compile and predict earthquake within a certain period of time and over a large area.

Earthquake after-effects are normally avoidable with better building construction, safety systems, early warning and evacuation planning. We just need to be more vigilance and plan for the worse. With strong infrastructures, We also need to prepare the people so that they know what to do when tremors occur.

It is important to stay calm and not panic if you are indoor. Stay away from items made of glass or anything that can fall and hurt you. It may also be advisable to take cover under a table. Do not use a naked light just in case there is a gas leak. Do not use the lift if you are in a building. Use the staircase, instead. Evacuation is only necessary when there are visible signs of structural defects (new cracks, etc).

If you are outdoors, remain in the open until the tremors stop. Try to stay away from buildings and overhead electrical cables. Try to avoid trees as well if possible.

Once the shaking is over, check your surroundings for injured people and dangerous conditions. Turn off gas only if you smell gas. If you are trapped, try not to move too much to conserve your energy and not to kick up dust. Tap on pipe or wall or use whistle to alert rescuers or others. Shout only when it is really necessary as you need to conserve whatever energy and strength you still have. You won't know how long you have to wait before help comes around.

Experiencing natural disaster can be very stressful and depressing. Apart from handling rescue effort, it is also important to take care of the psychological aspect of the victims. Another consideration also includes the health and epidemic issues of the quake-affected areas. The effects will be felt soon if not well taken care early. These areas are normally neglected when everyone is busy with rescue and relief efforts.
