Hot Lava, Mount Etna

Photo: Hot lava at Mount Etna
A river of molten lava flows through a channel in hardened lava after an eruption at Mount Etna in Sicily, Italy. Mount Etna, one of Europe's most active volcanoes, was created by the subduction of part of the northward-moving African plate beneath the Eurasian plate.
