地震是怎麼形成的英語介紹

Ⅰ 地震是怎麼形成的英文版

Formation of Earthquakes：
Earthquakes form when there is a vibration in the earth』 crust, causing a sudden release of energy. This energy is radiated out from the quake』s epicenter, in the form of seismic waves.
There are two types of seismic waves, the P-waves, or primary waves and the S-waves, also known as secondary waves. The P-Waves are the first waves to arrive ring an earthquake. They compress and dilate (push together and pull apart) rocks in the ground, and they can travel through solids and liquids. The S-waves arrive after the P-waves. They move more slowly than the P-waves.As they pass through the ground they cause the rocks to move from side to side.

The 2008 Sichuan earthquake (Chinese: 四川大地震; pinyin: Sìchuān dà dìzhèn), magnitude 7.9 Mw, occurred at 14:28:01.42 CST (06:28:01.42 UTC) on 12 May 2008. In China, it was named after the earthquake's epicenter in Wenchuan County, Sichuan province of the People's Republic of China (Chinese: 汶川大地震; pinyin: Wènchuān dà dìzhèn). The epicenter was 90 kilometres (56 mi) west-northwest of Cheng, the capital of Sichuan, with a depth of 19 kilometres (12 mi).[2] The earthquake was felt as far away as Beijing and Shanghai, where office buildings swayed with the tremor.[3] The earthquake was also felt in nearby countries.

Official figures (as of 14 May) state that 14,866 are confirmed dead and 66,286 injured,[4][1][5] while the state-run Xinhua News Agency reported that 19,565 (including 7,700 in Yingxiu, near the epicenter) are dead and 26,206 injured.[6] The Chinese government said that the death toll could reach 50,000.[7] Tens of thousands are missing, many of them buried, and eight provinces were affected.[8][9]It was the deadliest and strongest earthquake to hit China since the 1976 Tangshan earthquake, which killed approximately 250,000 people.[10]

Ⅳ 地震是怎樣形成的（英語）一定要英語還要小學的拜託了

The crustal plates squeeze each other, causing the internal stress existing or stretched or squeezed inside the plate. When a certain stress exceeds the limit that a plate can bear at a certain time, the ground will be pulled away by a crack or suddenly folded up and collapsed, creating an earthquake.
地殼板塊互相擠壓，導致內部應力存在或伸展或擠壓在板塊內部。當某一特定的應力超過某一板塊在某一時間所能承受的極限時，地面就會被裂縫拉走或突然折疊倒塌，造成地震。

Ⅳ 關於地震的英語介紹

An earthquake is a sudden tremor or movement of the earth's crust, which originates at or below the surface.

There are two main causes of earthquakes. They can be linked to explosive volcanic eruptions or can be triggered by tectonic activity, with the latter being the cause of most earthquakes.

Earthquakes in the UK are all tectonic quakes, triggered when the Earth』 crust is subjected to strain and eventually moves.

At the start of a quake there is a sudden movement within the Earth's crust and shock waves move out from that point.

The focus of the earthquake or tremor is often deep below the surface and difficult to map, so what is normally called the epicentre is taken as the point on the Earth directly above it.

There are two scales for defining the strength of an earthquake, the Mercalli Scale and the Richter Scale.

Earthquakes emit three types of waves which have their own characteristics.

Primary waves are identical in character to sound waves. The ground is forced to move forwards and backwards as it is compressed and decompressed.

Secondary waves travel more slowly and arrive after the P-waves. They move in all directions, at speeds which depend upon the density of the rocks through which they are moving. They cannot move through liquids. They can move walls and fences, leaving them 'S' shaped.

Surface waves are formed close to the epicentre and can only travel through the outer part of the Earth』s crust. They are responsible for the majority of the buildings damaged by earthquakes. The ground is made to move in a circular motion, causing it to rise and fall as visible waves move across the ground.

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. 地震和日常所見的風雨、雷電一樣，是一種較為普遍的自然現象。據統計，全世界每年約發生500萬次地震，不過99％以上的地震是微小地震，人們不容易感覺到。但強烈的突發性地震往往使人猝不及防，從而造成人員傷亡和巨大的經濟損失。

(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. 地球內部物質不停運動，會產生一股作用於岩層的巨大力量。當這股力量積累到一定程度時，可使一些岩
層發生彎曲、變形。一旦岩層承受不了這種變化的時候，就會發生急劇的破裂、錯動，引起強烈振動，這種振動就是我們平時所說的地震。
地球內部發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衡量。震級表示地震時釋放能量的大小；烈度表示地震對地面破壞的程度。
(三) Earthquake's type 地震的種類
(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引起的地震。組成地殼的岩層在地應力作用下，發生傾斜或彎曲變形， 當地應力繼續增強，積累到超過岩層所能承受的限度時，沿著岩層構造薄弱的地方。突然發生斷裂或錯位，使長期積累起來的能量急劇地釋放出來，並以地震波的形式向四周傳播而引起地面的振動。

(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 reces 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 proce. 火山地震是由火山爆發而引起的。火山地震主要有兩種：一種是火山爆發時， 由於岩漿沖擊地殼或使局部地區岩層發生變形和變位而引起的地震。另一種是火山爆發後，由於大量岩漿損失，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岩層斷裂或塌陷而產生的地震。
(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於地下溶洞或礦山采空區的陷落而引起的局部地震。

Ⅸ 地震時如何產生的，寫一篇英文作文

原文：地震是指岩石圈在內力作用下脫然發生破裂，地球內能以地震波的形式強烈釋放出來，從而引起一定范圍內地面震動的現象。

發生地震的原因很多，根據地震的成因，可以把地震分為以下幾種：

1．構造地震

由於地下深處岩層錯動、破裂所造成的地震稱為構造地震。這類地震發生的次數最多，破壞力也最大，約佔全世界地震的90%以上。

2．火山地震

由於火山作用，如岩漿活動等引起的地震稱為火山地震。只有在火山活動區才可能發生火山地震，這類地震只佔全世界地震的7%左右。

3．塌陷地震

由於地下岩洞或礦井頂部塌陷而引起的地震稱為塌陷地震。這類地震的規模比較小，次數也很少，即使有，也往往發生在溶洞密布的石灰岩地區或大規模地下開採的礦區。

4．誘發地震

由於水庫蓄水、油田注水等活動而引發的地震稱為誘發地震。這類地震僅僅在某些特定的水庫庫區或油田地區發生。

5．人工地震

地下核爆炸、炸葯爆破等人為引起的地面振動稱為人工地震。 人工地震是由人為活動引起的地震。如工業爆破、地下核爆炸造成的振動；在深井中進行高壓注水以及大水庫蓄水後增加了地殼的壓力，有時也會誘發地震。

地震發生時，最基本的現象是地面的連續振動，主要是明顯的晃動。在震區的人在感到大的晃動之前，有時首先感到上下跳動。這是因為地震波從地下向地面傳來，縱波首先到達的緣故。橫波接著產生大振幅的水平方向的晃動，是造成地震災害的主要原因。

地震對自然界景觀產生很大影響，最主要的後果是地面出現斷層和地裂縫。大地震的地表斷層常綿延幾十至幾百千米，往往具有較明顯的垂直錯距和水平錯距，能反映出震源處的構造變動特徵。但並不是所有的地表斷裂都直接與震源的運動相聯系，它們也可能是由於地震波造成的次生影響。特別是地表沉積層較厚的地區，坡地邊緣、河岸和道路兩旁常出現地裂縫，這往往是由於地形因素，在一側沒有依託的條件下晃動使表土松垮和崩裂。地震的晃動使表土下沉，淺層的地下水受擠壓會沿地裂縫上升至地表，形成噴沙冒水現象。大地震能使局部地形改觀，或隆起，或沉降。使城鄉道路坼裂、鐵軌扭曲、橋梁折斷。在現代化城市中，由於地下管道破裂和電纜被切斷造成停水、停電和通訊受阻。煤氣、有毒氣體和放射性物質泄漏可導致火災和毒物、放射性污染等次生災害。在山區，地震還能引起山崩和滑坡，常造成掩埋村鎮的慘劇。崩塌的山石堵塞江河，在上游形成地震湖。

英語翻譯：
Earthquake refers to the lithosphere in internal force descend from natural fracture, the earth in the form of seismic waves can strongly released, resulting in a certain range ground vibration phenomenon.

The earthquake many reasons, according to the genesis of earthquakes, can put divided into the following several earthquake:

1. Structural earthquake

Due to the deep underground strata rupture, by the collapse of the earthquake as structural earthquake. This kind of earthquake the most times, damaging the largest, accounts for about more than 90 percent of the world earthquake.

Volcanic earthquake 2.

Due to volcanic action, like the magma activity caused earthquake known as the volcano earthquake. Only in volcanic area can occur volcanic earthquake, this kind of earthquake accounts for only 7% of the world earthquake.

Earthquake collapse 3.

Due to the underground caves or mines top subsidence caused by the earthquake known as the collapse of earthquake. This kind of earthquake relatively small size, number are also few, although have, also often occur in cave cloudy limestone region or large-scale underground mining of mining area.

Ince earthquake 4.

Because of the initial impoundment of the reservoir and activities such as injection water caused by earthquake known as the inced earthquake. This kind of earthquake only in certain reservoir or oilfield area happen.

Artificial earthquake 5.

Underground nuclear explosion, explosives are caused by artificial ground vibration called artificial earthquake. Artificial earthquake is caused by human activities of earthquake. Such as instrial, underground nuclear explosion caused by blasting vibration, In deep water in high pressure and large reservoir impounding increased crustal stress, sometimes also can ince earthquake.

When an earthquake occurs, the most basic phenomenon is the ground of continuous vibration, mainly is obvious shaking. In the quake area people feel great shaking before, sometimes first feel about beats. This is because seismic waves from underground to ground came that p-wave first reach's sake. S-wave then proce the large amplitude of the horizontal wobble, is the main cause of the earthquake disaster.

The earthquake on nature landscape impact, the main consequence is ground faulting and ground fissure. Earthquake ground fault often to several hundred kilometers stretching dozens, often have the obvious vertical and horizontal distance from the fault fault, can reflect source in the tectonic change characteristics. But not all surface rupture directly with focal the movements of link, they can also be caused by seismic waves cause secondary influence. Especially surface sediments thicker areas, sloping edge, rivers and both sides the path, which often appear ground fissures are often the result of terrain factors, on the side without relying on shaking that under the condition of surface baggy and split. Earthquake jolts make elongate-shaped sinking, shallow groundwater suffers extruding will rise to the surface along the ground fissures, forming sandblasting take water phenomenon. Large earthquakes can make local terrain change, or uplift, or settlement. Make urban and rural road bran, rails distortion, bridge broken. In modern city, as underground pipes burst and cable was cut off water, power and communications caused by. Gas, toxic gases and radiation can cause fire and poisons, radioactive pollution and so on secondary disasters. In the mountains, the earthquake can cause landslides and landslides, often cause bury towns tragedy. Collapse of rocks blocked rivers, formed in upstream quake lake.
