Photos from lava lakes in the world: Erta Ale, Nyiragongo, Hawaii, Vanuatu

Desert, Salt & Volcanoes: Experience one of the geologically most active areas on the planet: the Danakil desert in northern Ethiopia. Highlights include Erta Ale volcano with its active lava lake and Dallol hydrothermal fields offering a surreal landscape of colors, salt, geysers and springs.

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!
