WHAT TO DO IN THE EVENT OF AN EARTHQUAKE
Having knowledge beforehand is the best way to prepare for an earthquake. Here are some easy things to remember when you feel an earthquake happening. Howcast
1. Keep yourself calm and not panic when an earthquake occurs. If you are in the house you can take cover under sturdy table and Hold on to it, protect your head with a bag or hand. Try not to be close to a closet or glassware, stay away from windows, mirrors cupboards, and shelves and get out of the house as soon as the tremor is over.
2. Don’t go through the door, unless you are sure the door is supported by a strong frame, because it can collapse instantly.
3. Remain living in buildings, both houses, offices, apartments, until earthquake shaking stops and safely goes out. Research shows that people are even injured while trying to jostle out buildings and run in various directions, so that collisions occur.
4. Don’t use an elevator.
5. Be careful with electricity that might be extinguished or a fire extinguisher system in a building that might function automatically
6. If you are in a tall building, get out of the building immediately. Use emergency stairs and do not use elevators. Try to find out the place of evacuation and emergency stairs beforehand, so you can immediately know the place to save yourself when an earthquake occurs.
7. If you are successful outside when an earthquake occurs, you should also be aware of tall buildings, power lines and trees. Stay away from buildings and high pillars because it is very dangerous if it collapses and power lines, afflicts the person below it. Earthquakes also sometimes cause landslides and therefore avoid areas near cliffs or cliffs, try to be able to be in the open and terrain. Exit the moving vehicle If you are in a vehicle that moves during an earthquake, you should leave the vehicle immediately. But, remember! Don’t panic when getting out of the vehicle and you have to stay calm
8. If the tremor of the earthquake has finished, be more aware of aftershocks. Vibration that occurs in aftershocks is sometimes greater than the first earthquake. If you are still near the house, make sure the stove is turned off. If the smell of gas smells, immediately cover and pull the gas cylinder connecting valve. If you suspect that electrical damage arises due to an earthquake, immediately turn off the power source at home so that there is no dangerous electrical surge.
Listening to the radio will help to find out information and guidance directed by the local authorities to remain in a protected condition. It is feared there will be aftershocks that are even bigger and dangerous than the previous earthquake.
9. Be prepared for possible shaking after the main quake.
