中国东部海域发生海啸的可能性分析

由强地震引发的印度洋大海啸在短短几个小时内就演变成了一场巨大的人间惨剧。这样的2004年12月26日自然灾害,人类能不能预防?它的形成机制是什么?我国历史上发生过海啸吗?在未来我国哪些地区会发生海啸?就上述问题,作了可能性分析。印度洋海啸的发生可以说既是天灾,也是人祸。人类虽说还不能控制地震、海啸等天灾的发生,但可以通过预报等措施来减轻它们造成的损失。我国历史时期曾发生过多次海啸,台湾周围海域是海啸的高发区域,其次是大陆架区域,渤海是低发区域。在未来,东海、南海,特别是台湾岛附近海域具备产生海啸的条件,即海南、台湾存在成灾条件;其次是上海,广州,也存在潜在的海啸危险;沿海其它城市亦应居安思危。
