唐山 里氏7.8级
1960年智利9.5级大地震

公元1976年7月28日,中国北京时间3时42分53.11秒,中国唐山市丰南一带突然发生里氏8.2级(国内测量为7.8级)强烈地震,23秒钟后,唐山被夷成废墟,682267间民用建筑中有656136间倒塌和受到严重破坏,242769人死亡,164851人重伤,直接经济损失达30亿元人民币以上.地震罹难场面惨烈到极点,为世界罕见.

angshan earthquake the film reminded many memories,the 1976 tangshan for experienced TangShanRen it was forever in my heart,32 years,32 years later,another catastrophe descends to TangShanRen,it may be the more able to understand,nor did they forget that the community to their help all volunteered to join the tangshan salvage team,but also because such,FangDeng and brother reunion.At that time FangDeng understand,how oneself can yao can have hate?That's own everton-star brother ah,can live much good,then it now she also forgave her mother.

23seconds,32years!only beacause the 23seconds that changed the world they were familiar with for ever !it has to take 32years to comfort the pain of the people deeply in heart.however disaster can not ruin the hope just like the way it destroy the buildings.it makes the peopel stronger contrary.the one who survived the earthquake values the second chance of the life to do meaning things for others and society.
I was deeply moved by the kinship between the girl and her mother.Family love likes a big tree ,it protects you from things that dangerous,it comforts you out of sadness!it is really good to be alive to share the warmly sunshine.
so cherish everyday !love our family and friends.
时间不够了,匆匆给你打了这么多,希望对你有帮助!O(∩_∩)O~

一般性很深、因为地表下是泥土、泥土下有地心、地心温度很高、人掉进去了,被救上来可能性很小

许多动物的某些器官感觉特别灵敏,它能比人类提前知道一些灾害事件的发生,例如海洋中水母能预报风暴,老鼠能事先躲避矿井崩塌或有害气体等等.至于在视觉、听觉、触觉、振动觉,平衡觉器官中,哪些起了主要作用,哪些又起了辅助判断作用,对不同的动物可能有所不同.伴随地震而产生的物理、化学变化（振动、电、磁、气象、水氡含量异常等）,往往能使一些动物的某种感觉器官受到刺激而发生异常反应.如一个地区的重力发生变异,某些动物可能能过它的平衡器官感觉到；一种振动异常,某些动物的听觉器官也许能够察觉出来.地震前地下岩层早已在逐日缓慢活动,呈现出蠕动状态,而断层面之间又具有强大的磨擦力,于是有人认为在磨擦的断层面上会产生一种每秒钟仅几次至十多次、低于人的听觉所能感觉到的低频声波.人要在每秒20次以上的声波才能感觉到,而动物则不然.那些感觉十分灵敏的动物,在感触到这种声波时,便会惊恐万状,以致出现冬蛇出洞,鱼跃水面,猪牛跳圈,狗哭狼吼等异常现象.动物异常的种类很多,有大牲畜、家禽、穴居动物、冬眠动物、鱼类等等.动物反常的情形,人们也有几句顺口溜总结得好：
震前动物有预兆,群测群防很重要.
牛羊骡马不进厩,猪不吃食狗乱咬.
鸭不下水岸上闹,鸡飞上树高声叫.
冰天雪地蛇出洞,大鼠叼着小鼠跑.
兔子竖耳蹦又撞,鱼跃水面惶惶跳.
蜜蜂群迁闹轰轰,鸽子惊飞不回巢.
家家户户都观察,发现异常快报告.
除此之外,有些植物在震前也有异常反应,如不适季节的发芽、开花、结果或大面积枯萎与异常繁茂等.
动物为什么能事前知道地震?因为许多动物的器官对自然灾害特别敏感,它们比人能提前知道灾害的来临.如1975年2月4日海城、营口发生的7.3级地震前一个半月,就有冬眠的蛇出洞；许多鹅惊慌失措,乱叫不进窝,有的还飞起来.震前一两天猪不吃食,用力爬墙、拱门.地震前两天小猎互相乱咬,十几条小猪的尾巴都被咬掉.一只黑母鸡就在2月4日地震时飞上了树.一条雌马甲鱼在埒前20分钟突然翻腾,跃出水面,并发出尖叫声.营口一生产队有6条牛,震前头一天,有4头牛打呆拼角,2头牛拼命用蹄子刨地；鹿场的一群梅花鹿突然乱跑乱窜,有的前腿被挤骨折.
中国科学院对鸽与地震关系进行了实验观察,发现鸽子的胫骨的腓骨之间骨膜附近,有种椭球状小体,比小米还小,约有百余颗,有神经连着,形如一串葡萄.它们对震动十分敏感,刺激振幅达十分之几微米,就引起神经电发放.生物物理所用100只鸽子实验.将50只鸽子腿上的小颗粒切除,另50只保留不动,在4级地震前,后者惊飞不已,前者安静如常.说明切除腿部颗粒后与中枢神经失去了联系.

1976 年7月28日3时42分 24万多人死亡,16万人受伤 惨不忍睹.

唐山大地震观后感
昨天晚上,爸爸对我和妈妈说：“今天,我们看“唐山大地震”,这是一部很好的电影,十分催人泪下!
　　爸爸打开了迅雷看看播放器,点了一下《唐山大地震》,电影就放了起来.这部电影很催人泪下.主角有“方大强”“元妮”“方登”“方达”.里面讲了,在1976年里的一天,方大强和妻子元妮在夜里去工作,可是,过了一会儿,他们就感觉有点不对劲,车子竟然动了起来,下车一看,原来是地震,元妮一看,就吵着要去救孩子,但是方大强阻止了元妮,自己却跑进了倒塌的楼房内,到了早上,方大强的尸体才被清理出来,元妮很伤心,不过她一想,还有两个孩子呢,还要救他们那.于是,便找了起来,就在她绝望的时候,有人喊：“元妮,方达和方登在这里,快来看一看那.”元妮一看,正是她的两个孩子,可是,当人们发现,如果,撬方达那边的话,那方登就会有事,如果,撬方登那边的话,那方达就会有危险,当人们告诉元妮的时候,她的心里又落上了一块大石头,人们再三询问元妮的时候,元妮犹豫地说：“救弟弟,救弟弟!”可当时,姐姐方登是清醒的,这话她听到了,她哭了.当人们把姐弟俩拉上来的时候,元妮抱着方登哭了,几分钟后,元妮跟着一辆车走了,过了一会,天空下起了雨,方登被雨水一浇,奇迹般的醒了,她被一个武警送到了一个集中营,随后,就被一对好心人领走了,她在忧伤中长大了,她去学了医.方登从一个拉小车的小工,干到了一个公司的董事长.
　　在2008年四川汶川大地震,中方登和方达,都去了救灾现场,他们偶然相遇了,并相认了,方达带方登回了家,他们的妈妈一看方登回来了,就忍不住跪了下来.
　　方登和她妈妈相认了相认了,带她去了墓地,看了方大强的墓地.方登伤心的哭了.
　　看了这部电影,我知道了人的生命是多么的脆弱.地震是多么的无情.我现在生活是多么的美好,所以,我以后要努力学习报效祖国.

绝大多数地震发生在地球最刚硬的部分—地壳和地幔上部边缘的岩石里面.那里的岩石在地应力的作用下发生破裂.这个破裂处就成为震源,震动从这里开始.
刚硬的岩石为什么也会破裂呢?
首先,正因为它是刚硬的,所以才会破裂.如果它象生面团那样有很好的塑性,就不容易破裂了.如果是液体,更无所谓破裂.绝大多数地震都发生在地下70公里以内,特别集中在地下5—20公里以上下,这不是偶然的.因为在地下较深的地方,温度高,压力大,在长期缓慢的力的作用下,虽是坚硬的岩石也具有一定的塑性,就不那么容易破裂.
岩石具有受力后发生破裂的性质,这是它会破裂的根据,但还得有力作用于它的身上才能使它破裂.在地下,存在着各种形式的力的作用,产生多种类型的破裂,但最主要的作用是地壳运动.
在地壳运动的过程中,地壳的不同部位受到了挤压、拉伸、旋扭等力的作用,在那些构造比较脆弱的处所,就容易破裂,引起断裂变动,这种变动成为地震的主要原因,全世界99%以上的地震,就是由于地壳的断裂变动造成的,这类地震称为构造地震.现在我们要预报预防的,主要就是这种构造地震.此外,火山爆发、洞穴坍塌等也可造成地震,但数量都很少,规模也很小.

额~~里氏震级相差一级,相差的能量是30倍左右.唐山地震是7.6级,汶川是8.0级.能量与震级的公式为：㏒E=11.8+1.5M 其中E表示能量,M表示震级...所以相差的能量应该是约为3.98倍..

　　李元妮说;没了,才知道什么叫没了!
　　我总是自以为,是一个行将成年的人,其实在我生活过的短短十六年光阴中,我可以说
　　是毫无阅历,至少,我总是不懂得珍惜的含义,而这部电影却第一次让我懂得,珍惜拥有
　　小盆里的蔬菜,鱼缸里的热带鱼,恩爱的夫妻,和睦而快乐的家庭,一切美好的事
　　都可以随着大地小小的抖动一次身体而成为过眼云烟,在这一切都成为过去后,我们可以指责老天的不公,痛惜失去的一切,可是在这一切牢牢握在我们手中时,我们可曾如此地珍视他们?
　　李元妮在片头给过女儿一个承诺,“明天,妈再给你买西红柿.”明天,一个多么平凡的字眼,我们的口中不也是有很多明天吗?——“今天太忙了,明天再回家看父母.” “今天累了,明天再做这些题.” “孩子,明天我再陪你玩.”,有时,我们确实是因为太累了,太忙了,把事情暂搁到了明天,可有时,我们是否是在“明天”真正解决了这些事,我们也许在明天来临时,以另一个理由将事情推到了更遥远的明天,然而我们可曾想过,我们其实就像是那只“明天再垒窝”的小猴子,今日复明日,直到有一天被突如其来的大雨浇个猝不及防.
　　而这部电影告诉我们的,恰恰便是这个道理.人生就像一棵秋天的大树,看似枝繁叶茂,充实繁密,然而秋风一打,树上的叶子便随风飘零了,往往这时,我们才意识到,我们还没有来得及,仔细看一看,我们身边熟悉的事物,因为这些事物,我们往往太过熟悉,熟悉到我们总是天真的以为,他们永远都会陪在我们身边,然而在灾难面前,人类永远是卑微而猝不及防的,自然界一点小小的变动,上帝一个小小的玩笑,都会让我们失去很多,往往这时,我们才知道失去事物的珍贵,因为没了,我们才知道什么叫没了.
　　很多人总是恐惧着世界末日的到来,然而恐惧又有何益,我们既然无力对抗自然,还不如好好珍惜生活中的每一天,多学一些知识,多陪陪父母孩子.我们不是圣人神仙,不可能解决人生中每一个未了心愿,但我们至少可以,多珍惜一下身边的一切,不要等到一切都没了,才知道什么叫没了
　　楼主自己再发散一下,

A:想楼上说的,在北国测也是这么大级数
B:地震对某一地区的影响和破坏和程度称烈度.一般而言,震级越大,烈度也越大,同一次地震,距离震中远近不同而烈度也不同.接近震中的地区烈度较大,受破坏的程度大,远离震中的地区烈度较低,受破坏的程度较轻.
影响地震烈度的因素,除了震级和震中距外,还与地质构造、震源深度有关.
C:明显是错误的,地震有范围影响.离的比较远的烈度小
D大地先是上下剧烈颠动,接着是左右摇晃.不管是哪的地震,地理上我们学过,纵波比横波会先传达到地面.说一起晃的只是人的感觉
所以,这个答案是:B

Tangshan: The Deadliest Earthquake
From Jennifer Rosenberg
At 3:42 a.m. on July 28, 1976, a magnitude 7.8 earthquake hit the sleeping city of Tangshan, in northeastern China. The very large earthquake, striking an area where it was totally unexpected, obliterated the city of Tangshan and killed over 240,000 people - making it the deadliest earthquake of the twentieth century.
Fireballs and Animals Give Warning
Though scientific earthquake prediction is in its nascent stages, nature often gives some advance warning of an impending earthquake.
In a village outside of Tangshan, well water reportedly rose and fell three times the day before the earthquake. In another village, gas began to spout out the water well on July 12 and then increased on July 25th and 26th. Other wells throughout the area showed signs of cracking.
Animals also gave a warning that something was about to happen. One thousand chickens in Baiguantuan refused to eat and ran around excitedly chirping. Mice and yellow weasels were seen running around looking for a place to hide. In one household in the city of Tangshan, a goldfish began jumping wildly in its bowl. At 2 a.m. on July 28, shortly before the earthquake struck, the goldfish jumped out of its bowl. Once its owner had returned him to his bowl, the goldfish continued to jump out of its bowl until the earthquake hit.
Strange? Indeed. These were isolated incidents, spread across a city of a million people and a countryside scattered with villages. But nature gave additional warnings.
The night preceding the earthquake, July 27-28, many people reported seeing strange lights as well as loud sounds. The lights were seen in a multitude of hues. Some people saw flashes of light; others witnessed fireballs flying across the sky. Loud, roaring noises followed the lights and fireballs. Workers at the Tangshan airport described the noises as louder than that of an airplane.
The Earthquake Strikes
When the 7.8 magnitude earthquake struck Tangshan at 3:42 a.m. on July 28, over a million people lay sleeping, unaware of the disaster that was to befall them. As the earth began to shake, a few people who were awake had the forethought to dive under a table or other heavy piece of furniture, but most were asleep and did not have time. The entire earthquake lasted approximately 14 to 16 seconds.
Once the quake was over, the people who could, scrambled out into the open, only to see the entire city levelled. After an initial period of shock, the survivors began to dig through debris to answer the muffled calls for help as well as find loved ones still under rubble. As injured people were saved from under the rubble, they were lain on the side of the road. Many of the medical personnel were also trapped under debris or killed by the earthquake. The medical centers were destroyed as well as the roads to get there.
Survivors were faced with no water, no food, and no electricity.
All but one of the roads into Tangshan was undrivable. Unfortunately, relief workers accidentally clogged the one remaining road, leaving them and their supplies stuck for hours in the traffic jam.
People needed help immediately; survivors could not wait for help to arrive. Survivors formed groups to dig for others. They set up medical areas where emergency procedures were conducted with the minimum of supplies. They searched for food and set up temporary shelters.
Though 80 percent of the people trapped under rubble were saved, a 7.1 magnitude aftershock that hit in the afternoon of July 28 sealed the fate for many who had been waiting under the rubble for help.
After the earthquake hit, 242,419 people lay dead or dying, along with another 164,581 people who were severely injured. In 7,218 households, all members of the family were killed by the earthquake.
Corpses were buried quickly, usually close to the residences in which they perished. This later caused health problems, especially after it rained and the bodies were again exposed. Workers had to find these impromptu graves, dig up the bodies, and then move and rebury the corpses outside of the city.
Damage and Recovery
Before the 1976 earthquake, scientists didn't think Tangshan was susceptible to a large earthquake; thus, the area was zoned an intensity level of VI on the Chinese intensity scale (similar to the Mercalli scale). The 7.8 earthquake that hit Tangshan was given an intensity level of XI (out of XII). The buildings in Tangshan were not built to withstand such a large earthquake.
Ninety-three percent of residential buildings and 78 percent of industrial buildings were completely destroyed. Eighty percent of the water pumping stations were seriously damaged and the water pipes were damaged throughout the city. Fourteen percent of the sewage pipes were severely damaged.
The foundations of bridges gave way, causing the bridges to collapse.
Railroad lines bent. Roads were covered with debris as well as riddled with fissures.
With so much damage, recovery was not easy. Food was a high priority. Some food was parachuted in, but the distribution was uneven. Water, even just for drinking, was extremely scarce. Many people drank out of pools or other locations that had become contaminated during the earthquake. Relief workers eventually got water trucks and others to transport clean drinking water into the affected areas.
After the emergency care was given, the rebuilding of Tangshan began almost immediately. Though it took time, the entire city was rebuilt and is again home to over a million people, earning Tangshan the name "Brave City of China."

Many people suffered great pain from the Tangshan Earthquake.
The big fire took hold of the house quickly.

唐山市及所属各县区地震前人口总数为122万余人加上流动人口
其中唐山市死亡13.59万人,占总人口106.19万人的12.8%；

由于时间关系我只是大概看了一下这电影,整体给我的感觉就是感人吧!我体会到了生命的脆弱,在灾难面前人类的无奈之情.其实我觉得母爱真的很伟大,尽管在二选一中内心是多么痛苦 那时重男的思想还是挺重的啊 !选择儿子留下女儿 手心手背都是肉呀!我可以深深体会到这位伟大母亲内心是经过多少的挣扎才开了这金口呀!幸好上天理解这位母亲 ,让她的女儿活了下来

The Tangshan Earthquake also known as the Great Tangshan Earthquake,was a natural disaster that occurred on July 28,1976.It is believed to be the largest earthquake of the 20th century by death toll.The earthquake hit in the early morning,at 03:42 local time ,lasted 23 seconds and killed 242796 people.Rebuilding infrastructure started immediately in Tangshan,and the city was completely rebuilt.Today Tangshan city is home to nearly three million people and is known as "Brave City of China."

那叫做地光 由于能量突然大量的释放产生的 地光是指大地震时人们用肉眼观察到的天空发光的现象.地光在文献中有不少记载.震前的地光现象非常突出.地光出现的时间大多与地震同时,但也有在震前几小时和震后短时间内看到的.其形状有带状光、闪光、柱状光、片状光等.颜色也是多种多样的.低空大气中出现的片状光、弧状光和带状光等多为青白色,地面上冒出的火球、火团则多为红色.

人活着应该如何抉择,在遇到无法改变我们困难的时候,我们应该选择有信心的战胜这种困难,只有自己有信心了,困难才会向我们低头,只有自己伟大了,困难才会渺小,不要放弃任何一次希望,哪怕在世界最大的灾难来临的时候,我们依然是有希望的.
看了这部电影,知道了人的生命是多么脆弱,地震是多么的无情,我现在生活是多么的美好,唯有好好珍惜现在.

用爱在心灵的废墟上重建家园 ——《唐山大地震》观后感 题记：23秒就可以让一座城市毁灭，10万个家庭流离，几十万个孩子失去父母、亲人……而在城市废墟上重新建起家园、在心灵的废墟上重新与血脉相连，却需要32年。 今天借小猪同学的光，有幸去看了期待已久的电影——《唐山大地震》。 每次只要有大片上映，媒体电视总是大肆宣传，但是很少有让我心动地想跑电影院看的。这次却例外！很多人是冲着冯导去的，我很俗，就是冲着明星去的。明叔、七哥——我最欣赏的两个演员，难得在同一部作品中出现，这样的机会对我而言值得珍惜。所以打从7·22电影上映开始，我就一直想找个时间去电影院领略一下他们的风采。其实时间是挺多的，就是少了一个伴。 某天在和小猪聊天中提到了这部电影，她也很感兴趣，于是相约找个大家都有时间的日子一起去恒隆看。昨天下午接到小猪短信说票已订好，今天下午两点。看到短信时我很激动，终于可以去看《唐山大地震》了！ 下午一点半，我俩在汽车站碰面后就直奔恒隆。看到电影院进出口都是《唐山大地震》的宣传海报，我的心情更激动了！小猪很了解我，说让我和海报合个影做个纪念，我当然愿意了，虽然不能和明叔、七哥真人合影，和名字合个影也挺知足的哈哈……（我的小孩子脾气又出来的。） 两点整，电影准时开演。不过商业片就是商业片，广告挺多的。 几分钟后，“唐山大地震”五个字终于出现在大荧幕上了。我一直盯着那变动的字幕，期待演员表里赶紧出现“张国强”、“陈道明”的名字，感觉自己又回到了“年少轻狂”的日子了。 七哥是第一个出场的，看着他的着装打扮，我心里那个乐啊！他的表情、他的声音依旧是那么熟悉，他挺适合这个角色的。看着他和一对儿女在一起的镜头，我感觉这一家子很幸福，七哥表现相当不错！可是他和徐帆的某组镜头真的让人看着别扭啊！记得七哥刚成名时经常说自己演感情戏很不习惯，我也不知道他和徐帆演感情戏的时候是否已习惯，反正我看着是替他捏把汗啊！ 我原以为七哥是这部影片的主演，大概是因为关注他的消息比较多的缘故吧！今天看到演员表的排序才知道，原来男主角不是他。 电影开始没多久，七哥就为“爱”献身了，我都还没反应过来呢，直到元妮撕心裂肺地嚎啕，我才惊叹：“啊，七哥就这么没啦！”真是意外，我心中的主角的出场就这么结束了！ 不过这个角色真的很令我感动，正如元妮后来所说的，“哪个男人能用命来爱我”，为这样的男的坚守一辈子，她不亏！ 七哥的演出告一段落，接下去就看晨儿和明叔的表现了。 话说《士兵》出来的演员现在真的是走到哪都能看到他们的消息了，绝对的红大发了！李晨居然能在冯导的电影中担当主角，这绝对是对他演技的一种肯定。作为突迷，我替他们现有的成就感到高兴。晨儿在在这部电影中的演出仍旧是那样帅帅的，与先前作品相比，现在更显成熟魅力。至于他演的这个角色，我就不做过多阐述，因为网上已经很多了。不过每次看到晨儿，我总会想到小丹，因为“年少轻狂”的那段“幸福时光”里，她最欣赏的就是晨儿演的吴哲了。如果小丹也和我们一起看这部电影的话，那就更加圆满了！ 陈道明，认识我的朋友都知道，他是我最最欣赏的演员！这部戏这么执着地想去电影院观看，不言而喻，因为明叔有演出。小猪说他很适合演这样的角色，因为在《我们无处安放的青春》里，我们已经领略过他所饰演的“慈父”的温暖形象。在《唐》剧中，他所扮演的养父，仍旧是全片最温暖最坚定的角色，你看了后就会觉得，生活里真的就是想要这样一个父亲，即使在困境里，他也会把女儿宠成一个公主。（说这话可不是贬低俺老爸啊，其实俺老爸也是很疼偶滴！

Year on July 28,1976,Beijing time 3:42 53.8 seconds after 23 seconds,that time for the Chinese people,it is definitely difficult to Shihuai of 23 seconds; and personal experience that for 23 seconds and survived the Tangshan ,The 23 seconds is more deeply branded into their memories can not fade the unspeakable pain and terror - 1976,July 28,3:00,42 minutes,53.8 seconds,Tangshan earthquake!23 seconds,is located in North China's Tangshan occurred as the magnitude 7.8 Richter earthquake; 23 seconds,more than 242,000 dead and 164,000 seriously injured people; 23 seconds,more than 7200 earthquake killed his family home,Tens of thousands of family disintegration,4204 to become orphans; 23 seconds,97% of the ground construction,55% of the destruction of production facilities; 23 seconds,transport,water supply,power supply,disrupted all communications; 23 seconds,the direct economic loss 3,000,000,000 yuan; 23 seconds,a million people have the industrial city was razed to the ground ......Exactly 30 years have passed,compared to 30,23 seconds appears to be how insignificant,but then a short period of 23 seconds,so that 30 years later,when people look back on the past very much saddened that the situation is difficult Kan.July 28,2006 is the 30th anniversary of the Tangshan earthquake in the days to come,in this special day,the People's Network channels sorted out some of the pictures 30 years ago to reflect that great pictures of the disaster,along with the readers cherish the memory of the earthquake were killed Victims who,together with an unprecedented recall that the struggle to earthquake relief.

答案很明确：地震是可以预测的,但预报需要准确的发生时间和震级、烈度,这一点很难做到,正因为这一点,我国的做法是：宁可不报.
地震预报分3个层次：长期预报,中期预报,临震预报.
长期预报：长期预报：是指对未来十年可能发生破坏性地震的地域预报.它主要是根据当地的地震地质、历史地震活动背景及地球物理背景作出来的.长期预报主要是为国家或省、自治区、直辖市人民政府确定地震重点监视防御区提供震情趋势依据,并为国家经济发展、国土利用等防震减灾工作提供参考.
中期预报：中期预报：是指对未来1-2年内可能发生破坏性地震的地域、强度进行的预报.它的依据是地区的地震活动情况及各种趋势性前兆观测资料.中期预报是为划分地震危险区、进行中期震害防御和地震应急准备工作提供依据.
临震预报的定义：对某地几天以内,在较小范围内可能发生的地震破坏性地震做出的预报叫临震预报.

专家说了,地震中远期预报,中国处于世界前列 !
但临震预报是一项世界性的难题.不准确的预报,给人们造成心理恐慌,扰乱正常的生活和工作；但突然降临的大地震,对毫无准备的人们来说,将会遭到毁灭性的打击,所以,我国的做法是：宁可不报.
世人皆知的唐山大地震：.耿庆国又从气象角度研究短临预报的方法,1975年5月写了第一篇有关论文,在北京市地震队内外进行交流,正式提出地震前30天内的短期临震气象要素五项指标异常的概念、特征及其震例.他据此预测了唐山地震,时间在30天范围内,地点在京、津、唐、渤、张地区.
以下为引用：
“中国地震界都知道有一个“唐山杨”,是个敢说话的人.1968年,唐山市防震工作上马,杨友宸着手组建唐山地震监测网.几年间,他在唐山市区内先后建立了40多个监测点,各监测点都由专人负责,每天向他上报数据.虽然他没有被任命为唐山市地震办公室主任,但却是实际负责人.
　　在40多个监测点中,有各厂矿监测台站,还有学校监测台站.虽然是一支业余监测队伍,但监测人员大都是本科生,不仅懂业务,也很有责任心.从1975年年底开始,各个监测点纷纷监测到异常情况.开滦马家沟矿地震台的马希融、山海关一中的吕兴亚老师、乐亭城关中学（“文革”中称乐亭红卫中学）侯世均老师……一些监测者根据自己的测量、计算,都发出了唐山即将有地震的预报.1976年年初,综合唐山市40多个地震台、站的观测情况,杨友宸在唐山防震工作会议上作出了中短期预测：唐山市方圆五公里内,1976年7、8月份或下半年的其他月份将有5到7级强震发生.
　　然而,眼看就要摸着大震了,组织上却通知杨友宸去干校劳动.就在大地震预计即将爆发的当口,杨友宸被迫离开了至关重要的地震预测岗位,只剩下两个业务不熟的人值班.
　　“从1968年到1976年,千难万苦地铺了那么大的一张监测网,不敢眨一下眼,夜以继日地工作,都是为了抓到这次强震.可是,风风雨雨多少年,最终却没报出来.失去了24万人,惨哪!”面对张庆洲,老人哭了.苍老的脸上,泪珠滚落了一颗,又滚落了一颗.
　　杨友宸的直白,将历史真相撕开了第一道口子.他的坦诚,也让张庆洲感到意外.
　　“知道我为什么愿意和你说吗?”老人缓缓地说：“我年岁大了,身体不好.再不说,就来不及了.”
　　“一边是县委书记的乌纱帽,一边是47万人的生命,反反复复掂哪.”
唐山大地震之前,各种预兆、科学参数都显示出有大地震要发生,但谁都不敢预测准确的发生日期,各路专家的预报都为了保证稳定的原因,被国家按住了没报.

唐山大地震中,有一个少为人知的“青龙奇迹”——距唐山市中心仅65公里的青龙县,在大地震中无一人伤亡.
　　1976年7月,国家地震局的一行人到北京市地震队听取汇报.国家地震局以汪成民为代表的一批同志坚持认为大震将近,但他们的意见没有得到重视.在这种情况下,汪成民做了一次“越轨”行为——在全国地震群防工作经验交流会的晚间座谈上,把“7月22日到8月5日唐山、滦县一带可能发生5级以上地震”的震情捅了出去.
　　青龙县科委主管地震工作的王春青听了通报,从唐山火速赶回县里.7月24日,青龙县“一把手”冉广歧顶着摘乌纱帽的风险拍了板,向全县预告灾情.7月25日,青龙县向县三级干部800多人作了震情报告,要求必须在26日之前将震情通知到每一个人.当晚,近百名干部十万火急地奔向各自所在的公社.青龙县的人几乎全被赶到室外生活.
这一违反政府常规的做法,保证了在惨烈的大地震中,青龙县无一人伤亡.

After I saw the movie ,I could not help crying out loud.I feel deeply sorry for the people who died in the earthquake,and this movie give me a new way to know more about the people who survived.The past has past,but those who carry on living sill still suffer from the great loss.
The movie describe a story about a mother and her two children.In the earthquake,the mother was forced to save only one of her children,and fianally she painfully chose her son.However ,the daughter actually survived on her own and was adopted by others,but she hated her mother for not choosing her at that time.They did not meet each other until 32 years later,when the Wenchuan earthquake struck China.At the end,the daughter understand her mother's love for her,and they hug each other,crying.
Although we can not escape from the natual disaster,but we have love.With love we can survive all the pains adn all the obstacles.Sometimes children may have doubt about their parents' love,but actually every parent has devoted all their love to their children.The daughter in the movie took 32 years to realize this.
Love is the greatest power to let human survive until now.

震前,有时天气大旱,但井水(地下水)却猛涨,甚至溢出地表.在多雨的季节里,井水本应逐渐上升,但却猛降,甚至干涸.有的地方,本没有水源,却有大量水从地下涌出等等.产生的原因是因地震孕育过程中,地应力不断增强,尤其在震中区附近,因地应力的作用；地壳活动随之加强.压性区水位会逐渐抬升；张性区在张应力作用下,水位会逐渐下降.尤其是地壳局部区域在地应力作用下遭受破坏,发生变形或加速位移,以及由岩层破坏而引起上下层间水的贯通,都会使水位产生急剧的升降运动,这就是利用地下水预报地震的依据.
地震后,由于地震使空中的粉尘数量大增,加上地磁地壳中金属矿物的加热影响使地面水份快速蒸发,也就是说在地震发生前应该有一段闷热的天气,而地震发生后地面和地下能量大面积释放加速了天空水气的饱和度,地震后,出现很多的裂缝,地球内部的热量大量的释放出来,同时使得地面温度升高,蒸发加强,并且使得地下的一些水汽沿着裂缝进入空气中,同时巨大的能量使这部分水气上升速度和高度大增而进入高空低温区域(同样的原理大型森林火灾也最终会以暴雨结束),这样就在地面形成很强的上升气流,空气震动可以引起水蒸气凝结(同样的原理古代有擂鼓求雨的方法),这些水气和粉尘就凝结为水或冰散落下来,所以地震后通常会形成降水.

Earthquake struck by many thrilling,on a matter of moving,moving on a Word,a smile touched ...I'll be a great event this year which sensation.May 12,2008,happened to Wenchuan-centric 8.0 earthquake.Wenchuan of Sichuan province is a quiet little town,backed by Qingcheng mountain,West dujiangyan and Chengdu,however,at 14:28 minutes,here the past calm,but the sudden break by the earthquake.Three days later,the PLA soldiers entered the town.They found the Wenchuan central primary school,the school has been cut down in an illustration,they had to use the cable car to concrete panels hanging up.However,where the most critical time,suddenly teaching building of ruins because aftershocks and the machine hanging operation undergone mobile,at any time are likely to collapse,and then again to enter the ruins of danger,rescuing is almost equal to die,then fire command a dead command,allowing people to drill into the ruins to the withdrawal right now,collapse until after entering,stable but at this point,several ruins from the soldiers just shout and found children.Although several soldiers heard retreat commands but still ignoring personal safety,the head was going to go in the ruins,then collapse occurred,a huge concrete blocks to see it in to the settlement,the few soldiers to drill immediately by another soldier was dragging,two guys in the above pull,the last ruins of soldiers being dragged to a security zone,a fresh from the ruins brought out a child soldier is knelt down crying,dragging his people said:you make me to rescue a child,please you let me go to rescue a!I can't save a!see this situation everybody cried,but all do nothing,just stand by and watch the ruins of the second collapse.Subsequently,the child or to dig out,but only one is still alive,sees a young soldier holding the survival of the little girl in the rain shrieks ran to the rescue when where the tent,the soldier was sobbing.See here,my tears have meant stayed.What a touching story,how fearless soldiers,their burning sun,rain,used his own life to ensure the safety of people; what a touching story,how selfless acts,they abandon the rest,as affected people lift the pieces with a heavy concrete panels,to the disaster the people born of hope; how moving action,how unselfish dedication,they embody the daughters of the indomitable spirit,the spirit of the team,they love to save people.Looking back,take a look at our own,we do not have to rescue people in scorching,having to rescue the wounded in the flood,nor in the ruins of difficult.Our job is to learn,our study does not need to have such a hard,tenacious spirit?learning is not a day to learn,to learn to have persistence,perseverance,only then will it be possible to success!Their image will deeply in the hearts of the people affected,but also deeply impressed in my mind!in the Wenchuan earthquake in our hero's army by such outstanding,to heal the spirit make Sunward to cry,the Earth is moved,this spirit I deeply admire,they are a wonderful person,this is me in the earthquake of that long moved!

1、地震是有些前兆的,但全世界现在还不能进行准确的地震预报
2、目前地震报警器这样的产品
3、其实,地震来的时候,跑是没有用的,你根本不可能有时间跑,关键是建筑要好.在离地震中心较远的地方,第一波地震（地震有两种波,其中之一会稍快些,另一个会慢些,这之间有时差的）过后,可以立即从建筑里面出逃,这段时间可用来逃生.
4、家中高处的物体要固定一下,比如花瓶,书,装饰品等,防止地震时掉下来砸着人

是由于地震是空中的粉尘数量大增,加上地磁地壳中金属矿物的加热影响使地面水份快速蒸发,也就是说在地震发生前应该有一段闷热的天气,而地震发生后地面和地下能量大面积释放加速了天空水气的饱和度,同时巨大的能量使这部分水气上升速度和高度大增而进入高空低温区域,这些水气和粉尘就凝结为水或冰散落下来,这就是地震后形成下雨的原因.

唐山大地震多

1976年7月28日3时42分53.8秒,中国河北省唐山、丰南一带（东经118.2°,北纬39.6°）发生了强度里氏7.8级（矩震级7.5级）,震中烈度Ⅺ度,震源深度23千米的地震.地震持续约12秒. 有感范围广达14个省、市、自治区,其中北京市和天津市受到严重波及.强震产生的能量相当于400颗广岛原子弹爆炸.整个唐山市顷刻间夷为平地,全市交通、通讯、供水、供电中断. 唐山地震没有小规模前震,而且发生于凌晨人们熟睡之时,使得绝大部分人毫无防备,造成242769人死亡,重伤16.4万人,名列20世纪世界地震史死亡人数第一.直接财产损失达30亿元以上.
汶川大地震,也称2008年四川大地震,发生于北京时间（UTC+8）2008年5月12日（星期一）14时27分59.5秒,震中位于中国四川省阿坝藏族羌族自治州汶川县映秀镇与漩口镇交界处、四川省省会成都市西北偏西方向79千米处.根据中国地震局的数据,此次地震的面波震级达8.0Ms、矩震级达8.3Mw（根据美国地质调查局的数据,矩震级为7.9Mw）,破坏地区超过10万平方千米.地震烈度可能达到11度.地震波及大半个中国及亚洲多个国家和地区.北至辽宁,东至上海,南至香港、澳门、泰国、越南,西至巴基斯坦均有震感.截至2008年9月18日12时,汶川大地震共造成69227人死亡,374643人受伤,17923人失踪.是中华人民共和国成立以来破坏力最大的地震,也是唐山大地震后伤亡最惨重的一次.

因为岩浆是在地下几十千米的软流层,是在地壳以下
地震时只是岩石圈错位,岩浆不会喷发!
而火山喷发时岩浆会喷发,同时,可能引起地震
