Landscape On Earth – Dallol Volcano   Leave a comment

  Here one can experience the highest average temperatures on the planet. A weather station recorded 34.4°C annual mean temperature.

During the day the temperature is above 40°C in shade. But of course, one should not forget there is no shade here!

Dallol Volcano is not a real 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.

Last time such explosion took place in 1926, some 1.5 km to the south-west from the main crater of Dallol Volcano. Now in the site of this explosion is located deep, 30 m wide, round pit, filled with orange brine.


The 1.5 by 3 km large crater of Dallol Volcano has formed by the collapse of salt layers. Multiple hot springs above the hot magma have washed out the salt layers, leaving voids, which at some moment have collapsed.


Will there be more explosions in future? Yes, it is most likely. An explosion can happen every second.

The area around the volcano is considered to be deserted because of the severe natural conditions, but people do live not very far from the volcano.
