Q. 1 B
Answer the follow
Sudden vibrations on the earth and shaking of the earth surface /ground are called an earthquake. These cause seismic waves leading to movements of the earth’s surface like tremors, shaking or it goes up-down. Shocks occurred due to an earthquake can be mild or intensified (acute).
Follow these steps in case you feel tremors:
● DROP to the ground; take COVER by getting under a sturdy table or other piece of furniture; and HOLD ON until the shaking stops. If there is no a table or desk near you, cover your face and head with your arms and crouch in an inside corner of the building.
● Protect yourself by staying under the lintel of an inner door, in the corner of a room, under a table or even under a bed.
● Stay away from glass, windows, outside doors and walls, and anything that could fall, (such as lighting fixtures or furniture).
● Stay in bed if you are there when the earthquake strikes. Hold on and protect your head with a pillow, unless you are under a heavy light fixture that could fall. In that case, move to the nearest safe place.
● Use a doorway for shelter only if it is in close proximity to you and if you know it is a strongly supported, load bearing doorway.
● Stay inside until the shaking stops and it is safe to go outside. Research has shown that most injuries occur when people inside buildings attempt to move to a different location inside the building or try to leave.
● Do not move from where you are. However, move away from buildings, trees, streetlights, and utility wires.
● If you are in open space, stay there until the shaking stops. The greatest danger exists directly outside buildings; at exits; and alongside exterior walls. Most earthquake-related casualties result from collapsing walls, flying glass, and falling objects.
If in a moving vehicle
● Stop as quickly as safety permits and stay in the vehicle. Avoid stopping near or under buildings, trees, overpasses, and utility wires.
● Proceed cautiously once the earthquake has stopped. Avoid roads, bridges, or ramps that might have been damaged by the earthquake.
If trapped under debris
● Do not light a match.
● Do not move about or kick up dust.
● Cover your mouth with a handkerchief or clothing.
● Tap on a pipe or wall so rescuers can locate you. Use a whistle if one is available. Shout only as a last resort. Shouting can cause you to inhale dangerous amounts of dust.
