国家地震局赈灾应急救援司司长
黄建发在新闻发布会上表示，
目前地震的准确预测仍是一个世
界性的难题，此次地震没有提前
预测到。
地震可以预测么
据新华社华盛顿5月21日电 在中国
以及世界其他一些国家，都有不少民
间的地震预测说法，比如动物的异常
行为、奇特天象出现等。美国专家琼
斯说，这些说法到目前为止都还没有
真正的科学依据。世界各国的很多科
学家曾不止一次地试图证实这些预测
的科学性，但到现在也没有找到十分
确凿的证据。
　　琼斯说，从另外的角度说，即便
这些异常可以作为预报地震的参考数
据，地震监测人员也不能仅仅依靠某
一个单独的异常现象作出地震预报，
因为这类异常可能只对应极小的地震
几率，假如误报了地震，直接和间接
损失往往也是相当严重的。　　
地震，特别是强烈地震之前，总会
出现一些异常现象，人们把与地震
发生有密切联系的异常现象称之为
地震的前兆。
下面这首民谣是群众在长期预测
地震中的总结，细读一下，对观察地
震是有极大好处的。
震前动物有预兆，群测群防很重要。 牛羊骡马不进圈，猪不吃食狗乱咬。 鸭不下水岸上闹，鸡乱上树高声叫。 冰天雪地蛇出洞，大猫携着小猫跑。 兔子竖耳蹦又撞，鱼跃水面惶惶跳。 蜜峰群迁闹轰轰，鸽子惊飞不回巢。 家家户户都观察，综合异常作预报。
失去“理性”的飞虫、鸟类
1976年7月25日，唐山以南天津大沽口
海面，“长湖”号油轮四周海面，一大群
深绿色翅膀的蜻蜓栖在船窗、桅杆和船
舷上，一动不动任人捕捉驱赶。
天津市郊木场公社和西营门公社都
看见成百上千只蝙蝠，大白天在空中飞。
唐山大地震前兆
动物界逃亡大迁徙
1976年7月25日上午，抚宁县100多
只黄鼠狼，大的背着或叼着小的从古
墙洞钻出，向村内大转移。26日、27
日，这群黄鼠狼继续向村外转移，一
片惊慌气氛。
不可捉摸的信息
秦皇岛附近水域作业的潜水员说，
他看见一条彩色绚丽的光带，像一条
金色的火龙，转瞬即逝。
1976年7月27日，唐山北部一个军
营里，几个士兵发现地下的一堆钢
筋，莫名其妙地迸发出闪亮的光，仿
佛一个隐身人在那里烧电焊。
《华西都市报》5月10日报道，四川绵竹市西南镇檀木村出现大规模蟾蜍迁徙，数十万蟾蜍拥挤着走上了马路。面对这一异常现象，村民们普遍表示担扰，害怕可能是地震或其他自然灾害的预兆。
汶川地震的前兆
2008年4月26日早上7时，湖北恩施市
白果乡下村坝村直径约百米、水深数
十米、常年不干的观音塘约8万立方米
的蓄水5小时内全部消失，水面突然出
现漩涡，并伴有轰鸣声。
震前应做哪些准备？地震来临，
在民房中、在公共场所怎么避震？
专家提出，学习必要的防震知识，
提高防震意识，做好防震准备，
对更好地保护身处险境的自己大
有好处。
地震来临, 我们如何保护自己呢
Life is beautiful.
We must love our lives.
In an earthquake
SPEED IS LIFE.
Let’s practise hiding.
地震前应做好防震准备，如清理杂物，保持门口、楼道畅通；固定高大家具，将重物下置，防止倾倒伤人；准备电筒、创可贴、水等物品，做成家庭防震包；腾空牢固家具的下方，以备藏身。
地震来临时，最重要的是要保持冷静，并灵活选择藏身之所：震时应就近躲避，震后迅速撤离到安全地方；室内避震时应选择易于形成三角空间的地方避震，如内墙墙根、墙角等，或躲避到厨房、厕所、储藏室等空间小的地方。震时切记不要站到阳台上和窗边。
学生在教室上课时遇到地震，
老师应疏导学生迅速抱头躲在课桌
旁，待地震过后迅速撤离；在操场的
学生可原地蹲下，注意避开附近高
大建筑物或危险物，不要回到教室中。
在商场、影剧院等公共场所遇到
地震时，应尽快找到结实的柜台、低
矮家具或柱子边、内墙角等处就地蹲
下，同时注意预防高空落物伤人。
在户外遇到地震时，应就地选择开
阔地蹲下，并注意避开变压器、电线
杆、广告牌、高烟囱、水塔、过街桥、
立交桥等构筑物。
