Satellite images show moment volcano spewed ash more than four miles into sky - Images shared by the European Space Agency have captured the eruption and lava flows

The latest Mount Etna eruption triggered an avalanche of volcanic material and sent ash miles into the air. Spectacular photos and videos capture the eruption of Europe's largest active volcano.

A massive eruption at Mt. Etna forced tourists to flee the volcano on Monday after a plume of high temperature gases, ash and rock “several kilometers high” billowed into the air above them, Italian authorities said.
