Magnesium is one element present in the volcano’s different rock layers.
鎂元素存在于火山的不同巖層中。
Since it diffuses slowly through crystalline rock, scientists can calculate rock ages by how much magnesium is present.
由于鎂元素在結(jié)晶巖層中擴散緩慢，因此科學(xué)家可以通過檢測鎂元素含量計算巖層的年齡。
Scientists found that almost all of the crystal layers on Santorini were deposited just before the eruption.
科學(xué)家們發(fā)現(xiàn)，圣托里尼島上所有的結(jié)晶巖層在火山爆發(fā)前幾乎全部沉積下來。
That meant that several cubic miles of hot magna rose from the depths of the volcano very rapidly.
這意味著，數(shù)立方英里的火熱巖漿從火山深處迅速噴發(fā)。
The magma melted and mixed with the rocks just below the surface immediately before the massive explosion.
在大規(guī)模的火山爆發(fā)前，巖漿融化后立即與地表下的巖石融合。
The volcano that had been sleeping for thousands of years woke in the blink of an eye.
因此，沉睡數(shù)千年的火山眨眼間噴發(fā)了。
Researchers don’t know what caused such a large volume of magma to rise so quickly, but their findings may give scientists a clue to help predict the next big eruption.
研究人員不明白造成這么多巖漿迅速噴發(fā)的原因，但他們的研究發(fā)現(xiàn)也許為科學(xué)家預(yù)測未來的大爆發(fā)提供參考線索。
GPS measurements show that the rim of Santorini is deforming right now, indicating that more magma may be on the rise.
根據(jù)GPS測量顯示，圣托里尼火山口邊緣正在扭曲，這預(yù)示著更多的巖漿可能正蓄勢待發(fā)。
