進入《中英對照讀新聞》Scientists get better view of magma under Yellowstone 科學家進一步了解黃石公園下的熔岩
◎李信漢
A big reservoir of hot, partly molten rock has been discovered beneath the famed Yellowstone National Park in the United States, but researchers said there is no added risk of volcanic eruption.
一個含有部分熔化的灼熱岩石的巨大岩漿庫，在知名的美國黃石公園被發現，但研究者說，這不會增加火山噴發的風險。
The findings in the journal Science show for the first time that the amount of magma beneath the surface is far bigger than previously thought.
這項發現刊登在《科學》期刊上，研究首次揭露在先前已知的岩漿庫表面下，還有一個更大的岩漿庫。
The reservoir lies 19 to 45 kilometers beneath the Yellowstone supervolcano and is more than four times bigger than the magma chamber that is already known to exist.
岩漿庫在黃石公園超級火山下方19至45公里的地方，它的容積比先前已知的岩漿庫大4倍。
Experts say there is one in 700,000 annual chance of a volcanic eruption at Yellowstone, which spans the midwestern US states of Wyoming, Idaho and Montana.
專家說，黃石公園的火山每70萬年噴發一次，黃石公園橫跨美國中西部州：懷俄明、愛達荷和蒙大拿。
The Yellowstone supervolcano last erupted about 640,000 years ago.
黃石公園超級火山上次噴發是64萬年前。
"The magma chamber and reservoir are not getting any bigger than they have been, it’s just that we can see them better now using new techniques," said co-author Jamie Farrell, a post-doctoral researcher at the University of Utah. （AFP）
論文的共同作者、猶他大學博士後研究員弗雷爾說，岩漿室和岩漿庫並沒有比之前變得更大，這只是因為我們現在使用新科技，所以可以對它們有更好的觀察。（法新社）
