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.
最近幾個月同時噴發的三座阿留申火山可能會與第四座火山一起噴發。位於西阿留申群
島的大衛多夫火山幾千年來一直不活躍。但是在休眠火山周圍測量的一系列地震讓一些研
究人員懷疑大衛多夫是否正在甦醒。
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.
大衛多夫是古老火山口的遺跡，高出白令海海平面1,000 多英尺。它位於遙遠的阿留申
群島西部的老鼠群島，在阿達克以西近 200 英里，它位於東半球。
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 年俄羅斯探險家開始記錄以來，這座火山就一直沒有活躍過。研究人員表示
，它的休眠時間可能比這更長，也許長達 10,000 年。
But a swarm of earthquakes shook the area beginning Dec. 7, and that has
researchers keeping a close watch.
但從 12 月 7 日開始，該地區爆發多次群發地震，這讓研究人員密切關注。

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觀測站的地球物理學家。他說，即使大衛多夫在
歷史上不被認為是活躍的，“創造阿留申島弧的板塊型造山俯衝過程並沒有停止”，
並且“仍有活動的可能性。”
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.
他說地震在一周內增加了，這可能表明地震不是由構造變化引起的，而是由火山下方的岩
漿流動引起的。
“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.”
“對於構造地震，通常第一次是最大的一次，然後是一堆餘震。所以我認為這個上週引起
了我們的注意，因為最大的地震不是第一次，”哈尼說。“所以這更像是火山地震序列，
引起了我們的注意。”
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.
大衛多夫太遙遠，無法威脅到任何社區，但哈尼說，它可能對航空運輸構成威脅。由於這
種可能性，AVO 上週五將 Davidof 的警告級別提高到黃色。
Haney says that in 2008, a similar string of earthquakes hit an area east of
Adak around Kasatochi Volcano.
Haney說，2008 年，一連串類似的地震襲擊了 Adak 以東的 Kasatochi 火山附近地區。
“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.
“出現了一個類似的問題：我們測量的這些地震是構造地震還是火山地震？在那種情況下
，地震活動加劇，火山最終在 2008 年大規模噴發，”哈尼說。
The earthquakes around Davidof continued through the weekend, but they don’t
seem to be intensifying.
大衛多夫周圍的地震持續了整個週末，但似乎並沒有加劇。
Still, Haney says, AVO’s team will be keeping a close watch from their
vantage point 1,200 miles away.
儘管如此，Haney 說，AVO 的團隊將在 1,200 英里外的有利位置密切監視。
