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。
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。
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。
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 lve ur 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。
