A sizzling summit hides in the clouds

Seen here with its explosive summit socked away in the clouds, Mount Etna towers over the Italian isle of Sicily as the tallest volcano in Europe—and maybe the crankiest, given its near-constant eruptions. The island peak has been highly active for perhaps half a million years and can still be counted on for a spectacular eruption every few years. This photograph shows Etna erupting in 2013.

云层中隐藏着一座炙热的山峰

埃特纳火山在意大利西西里岛上空耸立，是欧洲最高的火山，可能是最古怪的火山，因为它几乎一直在喷发。岛上的山峰已经高度活跃了大约50万年，仍然可以指望每隔几年就有一次壮观的喷发。这张照片显示埃特纳火山在2013年喷发。
