A team of geologists at the US Geological Survey, working with a trio of
colleagues from Oregon State University, and another from the University of
Wisconsin-Madison, has found evidence of rhyolitic volcanism in Yellowstone
caldera shifting northeast.

In their paper published in the journal Nature, the group describes how they
used an electromagnetic geophysical method to survey the ground beneath
Yellowstone's caldera.

美國地質調查局的一組地質學家與俄勒岡州立大學的三名同事和威斯康辛大學麥迪遜分校
的另一名同事合作，發現了黃石火山口流紋質火山活動向東北移動的證據。

在《自然》雜誌上發表的論文中，該小組描述了他們如何使用電磁地球物理方法來測量黃
石火山口下方的地面。

The Yellowstone Caldera is a volcanic caldera and super-volcano in
Yellowstone National Park, located in the Western United States—it has
sometimes been referred to as the Yellowstone Super-volcano because of its
massive size; it is one of the largest on planet Earth.

Prior research has shown that the super-volcano has experienced three major
caldera-forming eruptions in the past 2.1 million years—with the most recent
lava flow being approximately 70,000 years ago. It is not known when it may
erupt again.

黃石火山口是位於美國西部黃石國家公園的火山口和超級火山，由於其巨大的規模有時被
稱為黃石超級火山；它是地球上最大的之一。

先前的研究表明，這座超級火山在過去 210 萬年裡經歷了三次主要的火山口噴發，最近
一次熔岩流發生在大約 7 萬年前。目前尚不清楚何時會再次噴發。

In this new study, the researchers investigated the makeup of the material
beneath the caldera, which is part of a larger effort to better understand
volcanic eruptions in order to help predict when they might occur.

Prior efforts to gain an accurate estimation of the type and amount of
material beneath the Yellowstone caldera have led to mixed results due to the
extreme conditions. The research team took a new approach—they carried out a
major magnetotelluric survey across the entire caldera. Such an approach
involved measuring electromagnetic geophysical properties that take into
account variations in the Earth's magnetic field—it also allowed the
conductivity structure of the crust to be inferred.

在這項新研究中，研究人員調查了火山口下方物質的組成，這是更好地了解火山爆發以幫
助預測火山爆發何時發生的更大努力的一部分。

由於極端條件，先前對黃石火山口下方物質的類型和數量進行準確估計的努力導致了不同
的結果。研究團隊採取了一種新方法—他們對整個火山口進行了大規模的大地電磁調查
。這種方法涉及測量電磁地球物理特性，考慮到地球磁場的變化，它還可以推斷地殼的導
電結構。

The survey allowed the researchers to see that there are seven, and possibly
more, unique regions of magma residing beneath the caldera, with some feeding
into others, at depths ranging from 4 to 47 kilometers—near the boundary of
the mantle.

透過這項調查，研究人員發現火山口下方存在七個（甚至可能更多）獨特的岩漿區域，其
中一些岩漿注入其他岩漿區域，其深度範圍為 4 至 47 公里，靠近地函邊界。

The research team also noted that the most interesting melt storage
reservoirs were located in the northeast parts of the caldera, suggesting
they were likely to be the most active in the future. The reservoirs, they
found, hold basaltic magma in their lower parts and rhyolitic magma in their
upper parts.

The team was even able to make estimations regarding amounts—they found
there was a melt storage of approximately 388 to 489 cubic kilometers. An
amount that was much higher than in the south, west and north, which is where
prior eruptions had been centered.

研究小組還指出，最有趣的熔體儲存庫位於火山口的東北部，這表明它們可能是未來最活
躍的。他們發現，這些儲層的下部含有玄武質岩漿，上部含有流紋質岩漿。

團隊甚至能夠對數量進行估算—他們發現熔體儲存量約為 388 至 489 立方公里。這一
數量遠高於南部、西部和北部地區，而這些地區是先前火山爆發的集中地區。
