Dallol is a cinder -one volcano Erta ale Range in ethiopia

Dallol is a cinder- cone volcano in the danakil deepression northeast of the erta range in Ethiopia. the area lies up to 120 m (390ft) below sea level and has been repeatedly flooded in the past when waters from the red sea have inundated it. the danakil depression is one of the hottest places on Earth and the evaporation of seawater after these flooding episodes produced thick deposits of salt, as seen in this landscape. the deposits at dallol include significant quatntities of the carbonate sulafte and chloride salts of sodium potassium, calcium and magnesium. hot springs discharge brine to form the blueish ponds, and small, temporary geysers produce cones of salts
