美国十大地震州
Alaska and California have more earthquakes and more strong quakes than any other U.S. states. But depending on whether they count total number of quakes or the strongest temblors（地震）, geologists（地质学者）don't agree on ranking beyond that.比起美国其他州来，阿拉斯加州和加利福尼亚州要发生更多并且更强烈的地震。但是，除了参考地震次数和强度的数据外，地震学家们还没有采用其他的方法对容易发生地震的地区进行分级。
So John Anderson and Yuichiro Miyata at the University of Nevada, Reno, decided to investigate and create a formal list. Their Top 10 states, based on the greatest magnitude（地震级）achieved every year:
来自内华达州大学的约翰·安德森和Yuichiro Miyata决定调查并最终制作出一个正式名单。名单上，每年根据震级列举出美国十大地震州。
Alaska, 6.70
California, 6.02
Nevada, 5.11
Hawaii, 5.00
Washington, 4.97
Wyoming, 4.67
Idaho, 4.57
Montana, 4.47
Utah, 4.29
Oregon, 4.24
阿拉斯加州6.70
加利福尼亚州6.02
内华达州5.11
夏威夷州5.00
华盛顿州4.97
怀俄明州4.67
爱达荷州4.57
蒙大纳州4.47
犹他州4.29
俄勒冈州4.24
The list is far from reflecting the quake risk in many locations. For example, the Midwest is prone to（倾向于）infrequent but powerful quakes, and sooner or later one will strike that is liable to（易受）wreak havoc（严重破坏）across vast regions. Washington and Oregon, while not at the top of the new list, are both capable of suffering catastrophic（灾难的）damage in mega-quakes（超级大地震）that could near or exceed magnitude 9.0.
这份名单远没有反映出美国许多地方发生地震的危险情况。例如，美国中西部一般不容易发生地震，但一旦发生地震，那么震级将相当大，并且这种强烈地震在该地区迟早都要发生。华盛顿州和俄勒冈州没有排在这份名单的前列，但上述两个地区也有可能发生震级接近甚至超过9级的大地震。
"The reason for talking about this is not to change the rankings or to have one state move ahead of another—it's to motivate people to build structures that resist earthquakes," Anderson said. "If you're on this top-10 list, hopefully it will motivate you to be better prepared in the event of a large earthquake."安德森说：“讨论上述问题并不是要给美国容易发生地震的地区分级或者排名，而是要提醒人们在这些地区进行建设时要建造防震的建筑。如果你是在上述名单列举的地区，那么你最好做好可能发生大地震的准备。”
The study, published in the November/December issue of Seismological Research Letters, is based on actual quake accounts from 1568 to 1989 and seismological data from 1898 to 2005.
以上研究信息将会刊登在11月/12月出版的《地震研究》上，研究信息是参考了从1568年至1989年期间的地震总次数以及从1898年至2005年期间的地震数据做出的。
