求一篇1000字的英文作文,关于地震如何避难的
An earthquake is the shaking of the ground caused by an abrupt shift of rock along a fracture in the Earth,called a fault.Within seconds,an earthquake releases stress that has slowly accumulated within the rock,sometimes over hundreds of years.The size of an earthquake is indicated by a number called its magnitude.
Earthquakes have the power to uproot trees and send them crashing into buildings.They can trigger landslides and avalanches,and cause flooding and tsunamis.Human structures are also at risk.It is interesting to note that tall buildings will sustain the least damage if they are located directly at the epicenter.This is because they can withstand the up-and-down motion of P-waves.S-waves,on the other hand,occur far away from the epicenter,and cause the greatest stress by shaking buildings from side to side.These buildings are often knocked off their foundations.
Scientists are continuously thinking of ways to try and reduce earthquake power.Some are trying to lessen the friction between colliding plates.They poured water down a fault where two plates were grinding together.The water “lubricated” the fault,letting one piece jerk free with a number of little earthquakes and preventing a large tremor.Architects are also designing earthquake-proof buildings,constructing on rock instead of gravel,or on soft sand or clay.Researchers are always trying to reduce the impact of earthquakes.They continue to study and experiment with ways to tame the Earth.However,we all still have much more to learn before we can control the power of one of nature’s most amazing phenomena.Here are some guidelines to staying safe in earthquakes.
Things that you will need:Portable Radios,First Aid Kits,Fire Extinguishers and Flashlights;
Step 1
Stay inside and duck and cover.Get underneath a desk or table,or stand in a corner or under a doorway.Cover your head and neck with your arms.
Step 2
Move against an interior wall if in a high-rise building with no protective desk or table nearby.Cover your head and neck with your arms.
Step 3
Try to get into an open area away from trees,buildings,walls,signs and power lines if outdoors.
Step 4
Pull over to the side of the road away from overpasses and power lines if driving.Stay in your car until the shaking ends.
Step 5
Get away from shelves or other areas where objects may fall if in a crowded store or public area.Do not run for the door.Crouch and cover your head and neck with your hands and arms.
Step 6
Stay in your seat if in a stadium or a theater.Get below the level of the back of the seat and cover your head and neck with your arms.
Tips and Warnings:
· If you take cover under a sturdy piece of furniture,hold on to it and be prepared to move with it.
· Try to stay away from kitchens and garages,where there are often many objects that might fall.When the earthquake occurred,it is essential to have a clear-headed,calm composed attitude.If the earthquake when you are indoors,such as further away from the windows and doors,temporarily escape in a solid corner or under furniture,is relatively safe.In addition,can also be transferred to the load-bearing walls more,a smaller hall in the kitchen,bathroom,etc.take shelter.Escaped after the main shock,should be quickly evacuated to a spacious outdoor.When the need to protect the withdrawal of the head,preferably with pillows,quilts and other soft goods Huzhu head.
If the earthquake when you are outdoors open spaces,this is the most fortunate thing.If the building-intensive areas,the best hands or purses,and other soft goods Huzhu head,as far as possible,do a good job in self-defense preparations.And quickly left the transformers,poles and walls,a narrow roadway,and so on

If you have received possibly have the earthquake warning, continues
to maintain listens to the local broadcasting station newest report
and the suggestion, like the suggestion switches off the liquid gas,
the power source. Greatly but the heavy object from high will put on
to take away. The jar, the glass, the chinaware and other brittle
things admit in the low cabinet, the baggage shelf should have keeps
off the hand by to prevent the object whereabouts. The cabinet gate
should shut tightly, moves away to be hanging the object. Below
prepares the goods by to prepare urgently needs: Fresh fresh water and
emergency food, flashlight, fire extinguisher. Is far away these
possibly to fall is pounding your thing, possibly can eradicate in
outdoors trees, in the small town construction even if enough is
sturdy cannot destroy, the chippings also possibly fall. Runs away
spacious to place most ideal, but if does not have the enough time,
stays is possibly safer in the room, on the avenue speech, the gas
piping or the electric wire which bursts can increase the risk. Passes
in and out the human is most dangerous, extremely easily is wounded by
the building in bricks and stones.
In room: When the earthquake occurs, if in the indoors, stays in
inside, extinguishes the fire, is far away the glass is specially the
big window (including mirror and so on). In the room quoin or has the
good strut internal way is good seeking asylum place. Perhaps the low
ground or the basement can provide the best survival opportunity.
Hides in under the table bottom or other firm furniture, this not only
can provide the protection to you, moreover also has the big breath
space. When store, is far away the big cargo exhibition hall, these
cargos possibly can drop down. Also is loaded with the elevator in the
multilayered building in the office, in-situ hides in the desk bottom.
Do not enter the elevator, the staircase also possibly can crowd the
panic-stricken people. .
Che Zhong: As far as possible quickly and safely stops - but stays in
the vehicle may avoid hit by the whereabouts object. Crouches in
hiding under the seat, if has the thing to fall on the vehicle, you
will be able to obtain the protection. When vibrates stops down, the
attention observation obstacle and possibly appears danger: Destroyed
the electric cable, damages the path and collapses bridge.
Outdoors: When outdoors lie in the ground, do not have to run. This
can throw down, also possibly is embezzled by the crack. Is far away
the big construction. Toward underground walk or do not enter the
gallery, this can cause to be stranded. Like you already prepared to
the outdoors, did not return to in the building. The earthquake causes
any construction not too to be all reliable for the first time, if
then again occurs slightly
shakes, the building can cave in. Is safer
to the summit. In the pitch earth stone is easy to fall, if crushes by
the number thousand ton heavy soil block or the rock(they to have
fearful speed), very little has the opportunity which fortunately
survives. Rolls equally on the place like the ball changes the
survival.
Beach place: So long as under the cliff cannot the suitable security,
but because the tsunami follows the earthquake but to come frequently,
therefore after vibrates stops leaving the beach as soon as possible
to the higher open field shift. The aftershock risk did not like the
tsunami to be so fearful.
