Erta Ale volcano & Dallol (Ethiopia): Jan 2018 photos by Stefan Tommasini

Below you find a photo gallery with exceptional images captured by one of our very enthusiastic volcano adventurers, Stefan Tommassini (www.fotografie-mit-seele.de), during his travels to the Danakil desert with our Ethiopian volcanologist and expedition leader in January 2018. The photographs include aerial drone images of the colourful salt deposits, hydrothermal hot springs and acid ponds in Dallol as well as the lava lakes on both eruption sites on Erta Ale shield volcan; the summit caldera with the north and south craters and the flank eruption site which has been active since 20 January 2017. If you are interested in traveling to this exceptional part of our planet, check out our 14 days 'Desert, salt and volcanoes' expedition!
