灾难后的反思

地球怎么了?发生在海地和智利的地震带来的伤痛还没平息,我国青海玉树地区又遭受地动山摇的揪心;我国西南旱灾的干渴还未解除,南方多省市又遭遇暴雨及强对流天气袭击;冰岛火山灰遮天的威力还在让人们心有     

高中地理课程如何开展防灾抗灾知识教育

学校是人员密集的场所,青少年学生应对突发事件的能力差,一旦发生自然灾害,学校极易成为重灾区。对学生进行生命教育,掌握防灾抗灾知识、自救互救技能,培养生存能力十分必要。生命教育包括生     

地震成因新解

如果在缓慢滑动过程中,由于板块间某一个区域摩擦系数发生变化,存在一瞬间的"非匀速"状态,则会让人们感觉到细微的"震感"。这个发现,也恰好充分解释了这段时间各地"地震频发"的现象。     

Walls Collapse But the Structure Stands Still

In February 1996, an expert delegation from UNESCO visited Lijiang, southwest Yunnan Province of China for the assessment of the city＇s application for the World Cultural Heritage entry. Old architectures, historical streets and crisscross streams winding through them shape the old town of Lijiang and are the most important elements that the expert board planned to evaluate. Unfortunately, the visit coincided with a great earthquake of the region, Many new buildings fell down and roads were badly broken. But to their surprise, experts found that the old town was not destroyed as seriously as they expected. Wails of old houses and shops collapsed or damaged to some extents, but their structures stood still and maintained original forms. Ironically, some new, modern buildings that were at odds with the overall appearance of the old town collapsed. In the old town, roads remained intact and streams continued to flow as usual. Experts therefore asserted that with adequate restoration, historic, artistic and scientific values of the old town of Lijiang would not disappear and the application was still valid. In the end of 1997, Lijiang was approved to enter the list of World Cultural Heritage by UNESCO.     

记忆与认知——"抗震救灾研究专栏"编后记

在人类的历史记忆库存里,最难以忘怀的莫过于所经受的重大的事件、无情的战争或者巨大的灾难,它们就仿佛是一枚枚锐利无比的钉子锲入人类的柔软肌体,切进人类的骨髓内里,乃至沉淀为一种记忆雕刻。这些足以引起人类灵魂和精神痛感的东西,即使穷尽哲学的玄奥、理论的深瞻、想象的     

智利风铃草

智利风铃草是智利的国花,又称可比伟野百合,或者简称"可比伟",是当地称呼Copihue的音译。在蜿蜒巍峨的安第斯山脉西麓,智利就像一条黄灿灿的丝带面向广袤的太平洋。智利是世界上最狭长的国家,也是地质条件最为复杂的国家之一。智利西侧是一条狭长的海岸线,紧挨着的是细细长长的海岸山脉,海拔从300米到2000米不等,然后是比较宽的高原,海拔约1200米,最后到了东侧——安第斯山,最高海拔超过6000米。从西侧海岸到东侧安第斯山,最窄处只有90多千米。     

地震,伤不起

正地震真是个坏家伙,时不时地出来捣乱,不是严重破坏了建筑物,就是让人们无家可归。你不知道吧,它不是单枪匹马在战斗,还有好几个帮凶呢。从1976年唐山大地震到2008年四川汶川地震,再到2011年日本9.0级地震,今年四川雅安又发生了地震……地震活动越来越频繁,似乎成了可怕的代名词。     

受人木桃 报以琼瑶

5月12日下午2时28分,我们初二(3)班正在上信息课。在那时就开始地震了,开始只是晃动了一下,我们在信息室里没有什么察觉,过了大概有三四秒钟的时间,教学楼开始剧烈地晃动了,我们大家都往外跑(由于信息室是单独的,所以我们初二(3)班全部都活了下来,只有两位同学轻微擦伤,在操场上还有两个班在上体育课,所以北川中学当时只有三个班是完好的)。

地震知识

中国最早有记载的地震是哪一次?中国尧舜时代(公元前23世纪),发生在蒲州(现称)的地震。地震多发生在什么地方?地震的发生是受地质构造这个条件控制的。因此,地震的分布,多发生在那些活动构造体系内的活动构造带上,而且主要分布在存在着活动断层的地方。也就是说,地震的发生主要与活动断层有关。
