An earthquake is a phenomenon that results from and is powered by the sudden release of stored energy in the crust that propagates seismic waves. At the Earth's surface, earthquakes may manifest themselves by a shaking or displacement of the ground and sometimes tsunamis, which may lead to loss of life and destruction of property.
Earthquakes may occur naturally or as a result of human activities. In its most generic sense, the word earthquake is used to describe any seismic event—whether a natural phenomenon or an event caused by humans—that generates seismic waves.
地震是供給動(dòng)力結果從和由被存放的能量突然的發(fā)行在外殼繁殖地波的現象。在地球的表面, 地震也許體現自己由地面和有時(shí)海嘯的震動(dòng)或位移, 也許導致物產(chǎn)的喪生和破壞。
地震也許發(fā)生自然地或由于人類(lèi)活動(dòng)。在它的最普通的感覺(jué), 詞地震使用描述任何地震事件是否一種自然現象或事件造成由人引起地波。
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 “l(fā)ubricated” 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.

本來(lái)是第2個(gè)回的。回完了才想起來(lái)沒(méi)把中文的發(fā)上。
可是在回復中又顯示不出我的回復。半天才有。
害我等了半天才重新編輯。希望可以幫到你吧。
Understood that the earthquake and the earthquake protect the general knowledge 了解地震與地震防護常識 (1) earthquake is the common natural phenomenon 地震是常見(jiàn)自然現象 The earthquake and daily sees the wind and rain, the thunder and lightning are the same, is one kind of more universal natural phenomenon. Statistics indicated that the world approximately has 5,000,000 times every year the earthquake, but 99% above earthquakes are the small earthquakes, the people are not easy to feel. But the intense burst characteristics earthquake often causes the human to be unexpected, thus causes the personnel casualty and the huge economic loss. 地震和日常所見(jiàn)的風(fēng)雨、雷電一樣,是一種較為普遍的自然現象。據統計,全世界每年約發(fā)生500萬(wàn)次地震,不過(guò)99%以上的地震是微小地震,人們不容易感覺(jué)到。
但強烈的突發(fā)性地震往往使人猝不及防,從而造成人員傷亡和巨大的經(jīng)濟損失。 (二) earthquake's origin 地震的成因 The earth interior material does not stop the movement, will have an function in the rock layer tremendous strength. When this strength accumulates to the certain extent, may cause some crag the level to have, the distortion curving. Once the rock layer cannot withstand this kind changed, will have the sudden breakage, moving out of place, caused the intense vibration, this kind of vibration was the earthquake which we usually said. The earth interior has earthquake's place to call the center of origin, the ground to be apart from the center of origin recent place to be called the epicenter earthquake's size to be possible to use the magnitude and the earthquake intensity weighs. When magnitude expression earthquake emit energy size; The intensity expressed that earthquake degree which destroys to the ground. 地球內部物質(zhì)不停運動(dòng),會(huì )產(chǎn)生一股作用于巖層的巨大力量。
當這股力量積累到一定程度時(shí),可使一些巖 層發(fā)生彎曲、變形。一旦巖層承受不了這種變化的時(shí)候,就會(huì )發(fā)生急劇的破裂、錯動(dòng),引起強烈振動(dòng),這種振動(dòng)就是我們平時(shí)所說(shuō)的地震。
地球內部發(fā)生地震的地方叫震源,地面距震源最近的地方叫震中地震的大小可以用地震震級和地震烈度來(lái)衡量。震級表示地震時(shí)釋放能量的大小;烈度表示地震對地面破壞的程度。
(三) Earthquake's type 地震的種類(lèi)(1) Tectonic earthquake 構造地震 The tectonic earthquake is the earthquake which the earth structure movement causes. When the composition earth's crust's rock layer under the crustal stress function, has the incline or the bending strain, the local stress continues to strengthen, accumulates to surpasses the limit which the rock layer can withstand, along rock layer structure weak place. Has the break or the dislocation suddenly, causes the energy which accumulates for a long time to release suddenly, and to all around disseminates by the earthquake wave form causes the ground vibration. 構造地震是地球構造運動(dòng)引起的地震。組成地殼的巖層在地應力作用下,發(fā)生傾斜或彎曲變形, 當地應力繼續增強,積累到超過(guò)巖層所能承受的限度時(shí),沿著(zhù)巖層構造薄弱的地方。
突然發(fā)生斷裂或錯位,使長(cháng)期積累起來(lái)的能量急劇地釋放出來(lái),并以地震波的形式向四周傳播而引起地面的振動(dòng)。 (2) Volcanic earthquake 火山地震 The volcanic earthquake is causes by the volcanic eruption. The volcanic earthquake mainly has two kinds: One kind when is volcanic eruption, because the rock magma impact earth's crust or causes the earthquake which the local area rock layer occurs distorts and dislodges causes. After another kind is volcanic eruption, because the massive rock magma lose, the subsurface pressure reduces or the underground deep place supplies is inferior to, to present the cavity, thus causes the earthquake which the above cover's rock layer break or the collapse produce. 火山地震是由火山爆發(fā)而引起的。
火山地震主要有兩種:一種是火山爆發(fā)時(shí), 由于巖漿沖擊地殼或使局部地區巖層發(fā)生變形和變位而引起的地震。另一種是火山爆發(fā)后,由于大量巖漿損失,地下壓力減小或地下深處補給不及, 出現空洞,從而引起上面覆蓋的巖層斷裂或塌陷而產(chǎn)生的地震。
(3) The depression earthquake depression earthquake is the local earthquake which causes as a result of the underground limestone cave or the mine worked-out section's downcast. 陷落地震陷落地震是由于地下溶洞或礦山采空區的陷落而引起的局部地震。China earthquake intensity 中國地震烈度 Ⅰ 1.9 Does not have the feeling, only the instrument can record 無(wú)感,。

DURING an earthquake: 1. STAY CALM. 2. Inside: Stand in a doorway, or crouch under a desk or table, away from windows or glass dividers. 3. Outside: Stand away from buildings, trees, telephone and electric lines. 4. On the road: Drive away from underpasses/overpasses; stop in safe area; stay in vehicle.AFTER an earthquake: 1. Check for injuries -- provide first aid. 2. Check for safety -- check for gas, water, sewage breaks; check for downed electrical lines and shorts; turn off appropriate utilities; check for building damage and potential safety problems during aftershocks, such as cracks around chimney and foundation. 3. Clean up dangerous spills. 4. Wear shoes. 5. Turn on radio and listen for instructions from public safety agencies. 6. Use the telephone only for emergency use。
Dear friends
I'm sorry to hear that an earthquake happened to your hometown. The earthquake destroyed your hometown. Lots of houses fell down and some of you can't see your families any longer.
Please don't feel sad. You should believe in the Party, the government and the people in the country. Your heart should be full of wishes because the Party, the government and the people are with you all the time and they take care of you. They try their best to solve your troubles. They give away their money and many things for you and they donate blood for you.
So you should take care of yourselves. In the future, you should do something useful for our country to answer for their loves.
Yours,
XXX
When an earthquake occurs, it is essential to have a clear mind and calm attitude. Only calm, it is possible to use usually learned earthquake knowledge and determine the size and distance of the earthquake. Near the earthquake often above under the bumpy start, only after the left and right sway. Far less shake up and down feeling, and to sway around the main, and sound crisp, small vibration. In general, small and far earthquakes do not have to escape. It can be seen that earthquake, although the current human can not completely avoid and control, but as long as you can master the skills of self-rescue, mutual rescue, can make the disaster to a minimum.
地震發(fā)生時(shí),至關(guān)重要的是要有清醒的頭腦,鎮靜自若的態(tài)度。只有鎮靜,才有可能運用平時(shí)學(xué)到的防震知識并判斷地震的大小和遠近。近震常以上下顛簸開(kāi)始,之后才左右搖擺。遠震卻少上下顛簸感覺(jué),而以左右搖擺為主,而且聲脆,震動(dòng)小。一般小震和遠震不必外逃。 由此可見(jiàn),地震,雖然目前人類(lèi)還不能完全避免和控制,但是只要能掌握自救,互救技能,就能使災害降到最低限度。
