地震简介英文

An earthquake (also known as a quake) is the result of a sudden release of energy in the Earth's crust that creates seismic waves. The seismicity, seismism or seismic activity of an area refers to the frequency, type and size of earthquakes experienced over a period of time.

地震(也称为地震,地震或地震)是一个突然释放的能量在地球的地壳地震波产生的结果。地震活动,地震或地震活动面积是指频率,类型和在一段时间内经历了地震的大小。

There are three main types of fault, all of which may cause an interplate earthquake: normal, reverse (thrust) and strike-slip. Normal and reverse faulting are examples of dip-slip, where the displacement along the fault is in the direction of dip and movement on them involves a vertical component. Normal faults occur mainly in areas where the crust is being extended such as a divergent boundary. Reverse faults occur in areas where the crust is being shortened such as at a convergent boundary. Strike-slip faults are steep structures where the two sides of the fault slip horizontally past each other; transform boundaries are a particular type of strike-slip fault. Many earthquakes are caused by movement on faults that have components of both dip-slip and strike-slip; this is known as oblique slip.

有故障的三种主要类型,所有这些都可能导致板内地震:正常,反(逆)

和走滑。正常和逆冲断层倾滑的例子,在沿断层的位移是倾斜的运动方向上包括一个垂直分量。正常的故障主要发生在区域地壳被扩展,如发散边界。逆断层发生的地区,地壳缩短如在会聚边界。走滑断层陡构造,断层两侧水平过去彼此;变换边界是一种特定类型的走滑断层。许多地震是由具有倾滑和走滑断层的运动引起的成分;这被称为斜滑。

The earth is divided into three layers: the center layer is the core, the middle is the outer layer of the crust mantle. The mean radius of the earth is about 6370 km, the crustal thickness is about 35 kilometers, the most destructive earthquake occurred in the earth's crust. But the earthquake not only occurred in the crust, may also occur in the asthenosphere. According to the seismic section determination of deep earthquakes generally occur in the underground 300-700 km. So far, the deepest known source is 720 kilometers. From this point of view, the traditional plates the formation fracture theory can not reasonably explain the deep earthquakes, because the 720 km deep solid matter does not exist. Scientists think the earthout of the picture, it is of great help to predict earthquakes.

地球分为三层:中心层是地核,中间是地幔,外层是地壳。地球的平均半径为6370公里左右,地壳厚度为35公里左右,大多数破坏性地震就发生在地壳内。但地震不仅发生在地壳之中,也会发生在软流层当中。据地震部门测定,深源地震一般发生在地下300-700公里处。

到目前为止,已知的最深的震源是720公里。从这一点来看,传统的板块挤压地层断裂学说并不能合理解释深源地震,因为720公里深处并不存在固态物质。科学家设想将地球岩石图画出来,这样对预测地震有很大帮助。

Seismic activity in China are mainly distributed in 5 regions, these 5 areas are: Taiwan provinceand its adjacent waters; Southwest China, including Tibet, central Sichuan and Western Yunnan; the western region, mainly in Gansu, Qinghai, Ningxia, Hexi Corridor, Xinjiang north and south of the Tianshan Mountains; North China, mainly in Taihang Mountain, on both sides of the Fen Wei River Valley and the Yanshan area, central Shandong and the Gulf of Bohai;southeast coastal area, Guangdong, Fujian and other places.

中国的地震活动主要分布在5个地区,这5个地区是:台湾省及其附近海域;西南地区,包括西藏、四川中西部和云南中西部;西部地区,主要在甘肃河西走廊、青海、宁夏以及新疆天山南北麓;华北地区,主要在太行山两侧、汾渭河谷、阴山—燕山一带、山东中部和渤海湾;东南沿海地区,广东、福建等地。

关于地震的演讲稿

篇一:地震演讲稿 尊敬的吴老师,亲爱的同学们: 大家晚上好! 您还记得吗? 2008年5月12日下午14点28分。 您还记得吗?中国——四川——汶川县。 您还记得吗?2013年4月20日早晨8点02分您还记得嘛?——四川——雅安 看着这些熟悉的数字我的心是如此的沉重和苦涩 2013年4月20日早晨8点02分,当我们还在熟睡之际,梦想人生之时,雅安却发生了大地震,我们被这残酷的灾难所震醒,心被这残酷的灾难所震颤,在这天灾发生的一刻,我想到了那次汶川地震。它就像噩梦一样留在我们心中永远挥之不去。 那一次,四川汶川县发生了里氏八点零级地震,全国大半地区都有明显震感。它给人们和国家造成了严重的生命和财产损失。说它是大地震,是因为它比我们都知道的唐山地震还要严重,余震异常频繁,是新中国成立以来,一次史无前例的大灾难! 然而,在这如此恐怖的灾难面前,我们的中国子民没有退缩,我们一起手挽手去挑战地震----这个张牙舞爪的恶魔。 “一方有难,八方支援。众志成城,抗震救灾。”不错,当大地震发生后,全国乃至全世界都举行了捐款捐物捐衣捐水活动,各国人民也纷纷解囊相助,用爱心来为灾区人民营造幸福乐园。 两次地震给四川人民带来流离失所的悲痛,同时也体现了众多人们伟大的人格,在灾难降临的时候,四川人民没有退缩,中国人民没有退缩,他们抛弃了个人的一切,甚至写下遗书奔赴抗震救灾第一线。国家领导人不惜一切代价抢救灾情,为灾区人民送去温暖和希望。温家宝总理李克强总理在第一时间赶到了抗灾第一线,向灾区人民嘘寒问暖,表达了党中央对他们的爱护及关心。总理们在抗震前线吃的是馒头榨菜,每时每刻都往返在各个救灾帐篷之间?? 社会的各界仁人志士同样也为抗震救灾做出了很大贡献。他们有的是从全国各地赶来的志愿者,有的是没有遇难的本地人,有的则是来四川探亲的??他们也许失去了亲人,也许没有了家园,但是他们没有时间去过多悲痛,而是化悲伤为力量,为了灾区人民夜以继日地奔波着忙碌着。还有那些最可爱的官兵战士们,为了多救出一个灾民,为了早一分钟让灾民脱离危险,他们置自己的生死于不顾,和时间赛跑,和余震斗争,多么可爱的人啊,我们向他们致敬!在这块被灾难和阴霾笼罩的土地上,每一分每一秒都在回荡着一组组爱的交响乐! 用我们的爱心和行动,谱写出我们众志成城的一个好日子。阳光会灿烂,月亮会微笑,孩子的眼睛会被水灵灵的希望擦亮。我们手牵手,用一种不屈的精神一起去迎接美好的明天!我们手牵手,用一种伟岸的气魄一起去迎接美好的明天!篇二:地震演讲稿.doc 地震演讲稿-国旗下讲话:让我们唱响同一首歌 清风徐来,红日升起,雄壮激越的国歌旋律在校园的高空飘扬的时候,同学们,你有没有感受到这是多么幸福安宁的生活?你有没有为此对这份幸福充满感恩?这些日子,我是如此强烈地感受到了这些,但是我还想到了同一蓝天下却承受着巨大的痛苦的我们的四川同胞们,他们遭遇到毁灭性的人生浩劫,正经受着的家破人亡的悲伤,正面临着大片大片废墟的茫然无措。。。 真相是如此残酷,了解真相更是令人痛苦。但是,哪一个黑头发黄皮肤的的中国人不突然放下手头的工作泪眼婆娑地盯着新闻里一个又一个关于同胞们受灾的镜头,哪一个流着中国血喝着黄河水的中国人不倾耳收听抗震救灾的行动? 下面,我想就我所了解的四川地震的有关情况为大家作个具体的介绍。 北京时间5月12日14时28分,在四川汶川县(北纬31度,东经103.4度)发生7.8级地震。包括北京在内的近半个中国都有震感。此次四川地震震级高,又属浅源性地震,释放能量剧

汶川地震英语作文

汶川地震英语作文 汶川地震英语作文   Strong earthquake hits China A powerful earthquake measuring 7.8 has hit China's southern province of Sichuan, shaking buildings as far away as Beijing, Shanghai and Bangkok. It was not immediately clear if there were any casualties or damage from the tremor which the the US Geological Survey (UGS) earlier put at 7.8. The epicentre of the quake was 93 kilometres north of Chengdu. Wenchuan, which took full force of the quake, has a population of 111,000 people. It is in an ethnic Tibetan area in Aba county which recently saw violent clashes between Tibetans and Chinese authorities. According to some reports there was a second earthquake measuring 3.9 which hit the Beijing district of Tongzhou at roughly the same time.

关于防地震安全知识演讲稿

关于防地震安全知识演讲稿 我们要有防患意识、自我保护意识、珍爱生命意识,防灾意识。多学习一些防灾的知识,多掌握一些防灾抗灾的技能。下面是为大家整理了有关于防地震安全知识演讲稿3篇,希望能够帮到你。 关于防地震安全知识演讲稿篇1 亲爱的老师、同学们: 早上好,“星星火炬”广播现在开始,我是广播员钟宝仪。今天我广播的内容是“地震时我们该怎么办?”。 上星期,学校开展了地震演练活动,同学们都认真对待,积极配合老师,可是有一小部分同学嘻嘻哈哈,认为地震根本不可能发生在自己身上。其实,地球每天都在发生地震,一年约有500万次。地震,它就像刮风,下雨一样平常,是一种经常发生的自然现象,但是它破坏力很大,往往发生在瞬间。这就要求我们要有防患意识、自我保护意识、多学习掌握一些抗震技能。 如果我们在上课时发生地震,怎么办?我们要迅速抱头,闭眼,躲在各自的课桌下,背向窗户,用书包保护头部。服从老师指挥,有组织地撤离,防止发生踩踏,不可慌乱冲出教室,不可跳窗逃生。 如果我们在家发生地震,怎么办?我们要躲在坚固家具附近,内墙墙根,墙角,厨房,厕所,储藏室等开间小的地方。 如果我们逛书店发生地震,怎么办?我们要选择结实的柱子边或内墙角就地蹲下,用手或其他东西护头,避开玻璃门窗、玻璃橱窗或柜

台,不要慌乱,听从现场工作人员指挥。 如果我们不幸被埋压,怎么办?设法用砖头、木棍等支撑残垣断壁,防止周围杂物进一步倒塌,以防余震时再被埋压,不要随便动用室内设施,包括电源、水源等,也不要使用明火,闻到煤气及有毒异味或灰尘太大时,设法用湿衣服捂住口、鼻,不要乱叫,保持体力,用敲击声求救。 防患于未然,同学们,中午回家就自己动手做一个“地震包”吧。先找一个书包(可以是以前使用过的旧书包或背囊),里面放一些防灾用品:如口哨、手电筒、急救药品、火柴、蜡烛、毛巾、绳索、毛毯、写有家人血型的卡片等等,可以再放两瓶矿泉水及一些固体食品(譬如饼干、花生)。记得这些食品每隔一段时间更换一次,因为放久了会过期的。接着把这个“地震包”放在家门口一个醒目并且容易拿到的地方。如果灾难真的发生时,这个“地震包”或许会挽救我们的生命。 “星星火炬”广播到此结束,请大家明天继续收听,谢谢大家! 关于防地震安全知识演讲稿篇2 孩子是祖国的花朵,是民族的希望,是祖国的未来,如此美好的词汇昭示着孩子生命的宝贵。作为培育孩子的摇篮,我校一直都注重安全教育,经常开展各类安全讲座与展板宣传,并将安全理念渗透在每周一国旗下的讲话之中,宣传督促学生注意安全,快乐享受在校的美好时光。 一.地震知识

唐山大地震中英文双语简介

唐山大地震中英文双语简介 来自:贡献人:Alex创建时间:2010-07-26 11:28 冯小刚导演拍摄的《唐山大地震》电影上映,于此同时又让我们回到了1976年 The China Earthquake of July 28, 1976 (The Tangshan Earthquake) No other earthquake in this century has been as catastrophic or has claimed as many lives as the great earthquake that struck the city of Tangshan, in Northern China, on July 28, 1976. Tangshan, a thriving industrial city with one million inhabitants, is located only about 95 miles east, and slightly south, of Beijing. Although the region had experienced moderate seismic activity in the past, the city of Tangshan has been built on unstable, alluvial soil. To make matters worse, The city is located in the center of an area with major crustal faults on four sides. Furthermore, a 25-mile long fault passes through Tangshan, where only few of its structures are earthquake-resistant. In the early morning hours of July 28, while the city was asleep, the magnitude 8.0 earthquake with its epicenter right on the city broke a five-mile section of the fault. Along the west side of the fault the land moved five feet northward in relation to the land on the east side. The east block tipped downward at the northern end of the break, and upward toward the south end. Over a four-by-five mile area the devastation of the city was nearly total. The force of the quake motions were so strong that people reported being thrown in the air. Within seconds, thousands died. Property destruction was unbelievable. Bridges, railroads, homes, factories were completely leveled. In the harbor city of Tientsin, 60 miles to the southwest, and in Beijing to the west, the quake jolts forced thousands of frightened people into the streets seeking refuge from aftershocks. 中文翻译:

2021年汶川地震一个月:地震英摸报告会演讲稿

昨天晚上,收看了央视英模报告会。张泉灵的报告平实中积聚力量,真情流露中彰显令人震撼的敬业精神。 汶川地震英摸报告会的一篇演讲稿 中央电视台记者张泉灵 各位领导、同志们我是中央电视台记者张泉灵。5月12号,在珠峰呆了一个月之后我回到了拉萨,还沉浸在奥运火炬珠峰传递报道成功的喜悦中,大地震发生了。北京、台湾、日本都有震感!我的第一反应是唐山大地震影响到了14个省,这可能是比32年前更大的一次灾难,而前方灾情不明!情况不明的时候是最需要记者的时候!我得去现场!我知道高原下撤以后的第一原则是休息,我也很想家,想不满两岁的儿子。但是这时候到一线去,不是我个人的选择而是一种职业的天性。 经批准,5月13号,我挤上了震后拉萨飞往成都的第一班飞机。 帮助外面的人搞清灾区的情况是这个时候记者的第一责任。太多太多灾区的情况,抢险救灾的人要知道,受灾的群众要知道,党中央要知道。我觉得自己肩上的担子从未有过的沉重。到达四川的当天下午,我们报道组立即动身前往受灾最严重的北川。 交通断了,通讯断了,余震不断。尽管做了心理准备,灾难还是击碎了我的想象。要快,要让外面尽快了解灾区的情况。强迫自己冷静下来,雨中发回了我在灾区的第一条报道。 路,是生命线,也是抢险救灾的关键。奔向震中的途中我不停地问自己灾区的路到底怎么了?通向震中汶川的路为什么还不能打通?这个时候,我们必须把镜头对准这条路,去引导人们的视线。 5月14号,我沿着汶川方向,奔向213国道,踏进了打通道路的现场。观众看到了这样的情景几乎半座山塌下来,路不见了。而这条路原本只有7、8米宽,一边在塌方,一边是临着岷江的悬崖。工作人员上得去,但是展不开。这条报道,也许不那么惊心动魄,但是它把大家的疑问解开了,责难不见了,人们焦急的心情也冷静下来,开始积极地帮着出主意,怎样才能使修路的进展快一些。 在灾区的人民处在惊恐与悲伤中的时候,特别需要鼓起勇气,在废墟上没有比活着把人救出来更让人振奋的了。5月14号,都江堰的幸福小区发现了幸存者,救援者开始与死神搏斗。我想虽然压在废墟下的人我们连姓名都不知道,但电视机前有无数的人关心着她注视着她。我想让他们看到坚持,奋斗,我们就一定能获得重生!我向现场的领导建议直播救援过程。那天晚上,我知道很多人都守在电视机前,他们的心通过我们的直播与灾区紧紧地连在了一起。 那一片废墟有三层楼高,里面充满了空洞和尖利的钢筋,随时都有坍塌的可
