Vapour, explosions and maars
Travel photography
Family-friendly: true
Dallol Volcano is not a true volcano. Here, in the thick salt layers has intruded basaltic magma. As the groundwater descends deeper, it meets overheated rocks and turns into vapour. When the pressure of vapour reaches critical level, the ground (here - salt) above this superheated vapour is blown off in spectacular explosion, leaving a crater - maar.
