On March 27th, 1964, a huge earthquake struck the Prince William Sound, off the coast of Alaska. <>

1964年3月27日,在阿拉斯加海岸线的威廉王子湾发生一场大地震。<<阿拉斯加的海湾,海底陷入深渊,然后向上仰起整整50英尺,一股浪潮冲向海岸······>>

The quake is the second most powerful ever recorded, at 9.2 on the Richter scale, and it killed more than a hundred people. And just like the devastating Sumatra quake of 2004…or the Chilean quake in 2010…the great Alaska earthquake struck right around the time of the full moon. Coincidence?

这次地震是人类有记录以来第二大的地震,已达到9.2里氏震级,超过一百人死亡。然而和2004年苏门答腊地震、2010年智利地震一样,阿拉斯加大地震也发生在满月期间。这是巧合吗?

In 2016 Japanese researchers concluded that large earthquakes might indeed be more likely to occur during times of significant tidal stress… when it's either a new or full moon. And the news rumbled through the media, despite the study's small sample size, of just a dozen large quakes.

2016年日本科学家推测在新月或满月出现时,可能确实更容易在潮汐力的作用下发生大地震…这则新闻在媒体中广泛传播,尽管研究样本数量较小——只有几次大地震

Now seismologist Susan Hough of the U.S. Geological Survey has done a much larger analysis. She plotted more than 200 big quakes—magnitude 8.0 or above—over the past four centuries, looking to see if they were more likely to strike on certain days of the year, or during key phases of the moon. The answer, neatly summed up in the study's one-word abstract? "No."

现在地震学家苏珊·霍夫(Susan Hough)已完成对更多样本的分享。她调查超过200次大地震——过去四个世纪的8.0级以上的地震,来研究大地震是不是在一年中的特定某天或特定某种月相时更容易发生。答案,几乎用一个词就能表述:“不是”

The study is in the journal Seismological Research Letters. [Susan E. Hough, Do Large (Magnitude ≥8) Global Earthquakes Occur on Preferred Days of the Calendar Year or Lunar Cycle?]

这项研究发表在《地震学研究简讯》(《Seismological Research Letters》)杂志上

That's not to say we don't know of certain factors that actually do increase the risk of quakes. Hough says the ground injection of wastewater, oil and gas production, fracking, and damming up waterways can in some cases cause quakes. Just don't blame it on the moon.

但这并不说明我们不知道真正能够增加地震概率的因素。霍夫说开采石油和天然气后向地下注入的废水,在某些时候会引发地震。就不要再怪月亮啦。
