The three Aleutian volcanoes that have been erupting simultaneously in recent
months could be joined by a fourth. Davidof Volcano in the Western Aleutians
has remained inactive for thousands of years. But a series of earthquakes
measured around the dormant volcano has some researchers wondering if Davidof
is waking up.
最近几个月同时喷发的三座阿留申火山可能会与第四座火山一起喷发。位于西阿留申群
岛的大卫多夫火山几千年来一直不活跃。但是在休眠火山周围测量的一系列地震让一些研
究人员怀疑大卫多夫是否正在苏醒。
The remnant of an ancient caldera, Davidof rises over 1,000 feet out of the
Bering Sea. It’s located in the Rat Islands in the far Western Aleutians,
nearly 200 miles west of Adak — so far west that it’s in the Eastern
Hemisphere.
大卫多夫是古老火山口的遗迹，高出白令海海平面1,000 多英尺。它位于遥远的阿留申
群岛西部的老鼠群岛，在阿达克以西近 200 英里，它位于东半球。
The volcano hasn’t been active at least since the time Russian explorers
started keeping records in 1760. Researchers say it has likely remained
dormant for much longer than that, perhaps as long as 10,000 years.
至少自 1760 年俄罗斯探险家开始记录以来，这座火山就一直没有活跃过。研究人员表示
，它的休眠时间可能比这更长，也许长达 10,000 年。
But a swarm of earthquakes shook the area beginning Dec. 7, and that has
researchers keeping a close watch.
但从 12 月 7 日开始，该地区爆发多次群发地震，这让研究人员密切关注。

Matthew Haney is a geophysicist with the Alaska Volcano Observatory in
Anchorage. He said that even though Davidof is not considered historically
active, “the process of subduction that leads to volcanoes along the
Aleutian Arc hasn’t stopped,” and “the possibility remains for there to be
activity.”
Matthew Haney 是安克雷奇阿拉斯加火山观测站的地球物理学家。他说，即使大卫多夫在
历史上不被认为是活跃的，“创造阿留申岛弧的板块型造山俯冲过程并没有停止”，
并且“仍有活动的可能性。”
He says the earthquakes increased in magnitude over the week, which could
suggest the earthquakes weren’t caused by tectonic shifts, but rather by
magma flowing beneath the volcano.
他说地震在一周内增加了，这可能表明地震不是由构造变化引起的，而是由火山下方的岩
浆流动引起的。
“With tectonic earthquakes, typically the first one is the largest one, and
then there’s a bunch of aftershocks afterwards. So I think this one caught
our attention last week because the largest earthquake was not the first one,
” Haney said. “So that is something that catches our attention that’s more
like a volcanic earthquake sequence.”
“对于构造地震，通常第一次是最大的一次，然后是一堆余震。所以我认为这个上周引起
了我们的注意，因为最大的地震不是第一次，”哈尼说。“所以这更像是火山地震序列，
引起了我们的注意。”
Davidof is too remote to threaten any communities, but Haney says it could
pose a hazard to airline traffic. AVO raised the warning level at Davidof to
yellow last Friday due to that possibility.
大卫多夫太遥远，无法威胁到任何社区，但哈尼说，它可能对航空运输构成威胁。由于这
种可能性，AVO 上周五将 Davidof 的警告级别提高到黄色。
Haney says that in 2008, a similar string of earthquakes hit an area east of
Adak around Kasatochi Volcano.
Haney说，2008 年，一连串类似的地震袭击了 Adak 以东的 Kasatochi 火山附近地区。
“A similar question arose: are these earthquakes that we’re measuring
tectonic or volcanic? And in that case, the earthquake activity intensified
and the volcano ultimately erupted in 2008 in a large eruption,” Haney said.
“出现了一个类似的问题：我们测量的这些地震是构造地震还是火山地震？在那种情况下
，地震活动加剧，火山最终在 2008 年大规模喷发，”哈尼说。
The earthquakes around Davidof continued through the weekend, but they don’t
seem to be intensifying.
大卫多夫周围的地震持续了整个周末，但似乎并没有加剧。
Still, Haney says, AVO’s team will be keeping a close watch from their
vantage point 1,200 miles away.
尽管如此，Haney 说，AVO 的团队将在 1,200 英里外的有利位置密切监视。
