那么多孩子啊,人们怎么能够承受这样的悲痛啊

需要补充的是(ZT):这次四川汶川县出现的大地震,很多人都会疑问,这么大的地震为什么之前都没有预报到?地震究竟能不能预报呢?

省地震局局长丁仁杰介绍,地震多数发生在地下15公里以下的地壳里,当前人类对于地壳的研究只能通过钻机钻至地下12公里,远远做不到直接观察到地震孕育发生的全过程,只能在地表凭借有限的仪器设备捕捉地壳内部结构和状态变化的间接信息,以此来判断地震发生的可能性。

专家说,地震预报是一个全球性的难题;到目前为止,还没有哪个国家、哪个科学家有办法能把地震准确地预报出来。在此之前,我国也曾有极少数成功预报的先例,然而,由于各地的地震地质环境差别巨大,历史地震记载不全,地震观测站点密度偏少以及地震预测理论水平等原因,对地震做出准确预报现在还做不到。尽管地震所在地区也会出现一些先兆,但能否用于临震预报,还要积累和研究。

为什么没能及时地预报呢?

科技还没有发展到能够预测地震的地步。有些人以为存在这样的能力,是对一些事后孔明的夸张报道吹得过分而造成的误解而已。

有些黑人和白人可以感知

地震前其身体有一些不寻常征兆.

难道地震前一点征兆也没有吗?那怕只有几分钟,孩子们也可以逃出教室。

我也一直很纳闷,为何这么强烈的地震竟然事先没有测到?????

可惜,人类目前还没有这个能力。

Agree ! Prediction of earthquake is not an exact science.
