Kelut volcano photos
: A new lava dome grew inside the crater lake during the effusive eruption in late 2007, replacing most of the lake. Watch the birth of a new mountain!
Climbing Stromboli volcano
: Stromboli provides one of the most remarkable opportunities to watch volcanic eruptions from close: a natural ridge located 150 m above the active vents. A classic and all-time favorite tour by anyone interested in seeing active volcanoes!
