朝鲜核试验的科学意义 今天看到 GeophysicalResearch Letters 最新发表文章有一篇是关于去年朝鲜第三次核试验的相关研究。突然想起,朝鲜核试验对于地球物理研究者来说其实就是一次超级人工地震,对于地球物理研究来说是非常难得的数据。尤其在 2010 年日本 9 级大地震之后,对于中国东部的地震危险性有很多的关注。 首先,从俗气的角度看,朝鲜提供免费震源,周边国家的地球物理研究者轻轻松松发表了 20 篇 SCI 文章,都是地球物理学方面的顶级刊物啊!详见后面的列表。 其次,从地球物理探测的角度看, 2010 年日本 9 级大地震之后,中国东部迫切需要进行新的地震危险性评估,朝鲜核试验完全可以看作是多次次人工控制的地震,有理由将其用于研究日本大地震前后中国东部地壳结构和应力状态的变化等。 再次,可以利用朝鲜核试验研究核爆监测技术,增强中国在核爆监测方面的能力。 甚至,可以进一步研究核爆对地应力的影响,开发出解除地震灾害的干预方法。 有报道鼓吹美国专家认为朝鲜要进行第四轮核试验,只不过中国成了绊脚石。看来,没有哪个国家不希望朝鲜核试验,只有中国想不到益处。不知道这科学意义算不算!
