Eruption clues: Researchers create snapshot of volcano plumbing

Researchers have studied the journey of magma, or molten rock, in one of Europe’s largest and most active volcanoes, Mount Etna. They applied several techniques to create a more accurate picture of the volcano’s plumbing system and how quickly the magma rises to the top to cause an eruption. Their findings contribute to our understanding of how and when volcanoes erupt.
