Danakil Depression, where salt plains meet fiery geology
Published on 08/21/2026 at 10:38 | Editorial responsibility: Rafael Müller, Editor-in-Chief AD HOC NEWS
The Danakil Depression near Dallol in Ethiopia is a place where a broad salt plain, active volcanism and striking hydrothermal pools share the same low-lying basin. Set in the northern Afar region at the junction of major tectonic plates, it combines an arid landscape with vivid mineral formations that feel otherworldly yet are grounded in the rift geology of north-east Africa.
A salt basin below sea level in the Afar rift
The Danakil Depression is a rift basin in northern Ethiopia, forming the northern part of the wider Afar Depression where the Nubian, Somalian and Arabian plates, together with the Danakil microplate, pull away from one another.the triple junction between the Nubian, Somalian and Arabian plates This tectonic setting has created a narrow, elongated lowland that lies significantly below sea level, with parts of the basin floor reaching around 120 m (394 ft) beneath it.one of the lowest land areas in Africa
Across much of its northern half the Danakil Depression is filled by a broad salt pan known as the Dallol salt flat, an elongate halite-floored basin that forms the deepest part of the depression.the northern half of the Danakil Depression is dominated by a salt pan Beneath this surface lies a thick succession of evaporite deposits, including extensive rock salt formations and potash-bearing layers that have attracted geological interest and mining over many decades.a thick evaporite depocentre near Dallol The visual impression for a visitor is of wide, pale salt plains interrupted by low ridges and darker volcanic features.
Dallol dome and hydrothermal pools
Just above the salt flat rises Mount Dallol, a halo-volcanic dome structure composed largely of uplifted salt deposits. The dome stands several tens of metres above the surrounding basin and has an elliptical outline with bedded halite and anhydrite layers that dip gently away from its centre.the Dallol dome is a complex 40 m-high geological structure Basaltic magma intruded into Miocene salt deposits here, giving rise to the salt dome and the unusual hydrothermal system hosted within it.intrusion of basaltic magma in the marine sedimentary sequence
The Dallol geothermal area is characterised by colourful brine pools, mineral crusts and small geyser-like vents scattered across the salt surface. Brines rich in different elements precipitate bright deposits, so the ground here shows patches of yellow, green, white and rust tones against the pale salt and darker volcanic material.the Dallol geothermal area with brines, active geysers and saline systems The contrast between the flat salt pan and the textured dome, with its pools and terraces, is one of the most striking aspects of the Danakil Depression near Dallol.
Rifting, volcanism and salt over geological time
The Danakil Depression forms part of the East African Rift System and represents a segment of young oceanic crust, where continental breakup has progressed to the stage of a developing rift floor below sea level.a segment of just-formed oceanic crust Flood basalts of the Afar Stratoid Series cover much of the wider depression, while in the Danakil area shield volcanoes, cinder cones and salt lakes mark the rift axis and its surroundings.the floor is cut by faults and dotted with shield volcanoes
Over geological time the basin has repeatedly been flooded by seawater and then isolated, allowing thick sequences of gypsum, halite and other evaporites to form as the water evaporated in the hot, arid climate.thick evaporite sequences of gypsum and halite were deposited These deposits were later affected by tectonic faulting and magmatic intrusions, producing salt domes such as Dallol and creating pathways for hydrothermal fluids that now reach the surface. The resulting landscape combines young volcanic features with older sedimentary and evaporitic rocks, giving travellers an unusually clear view of how rifting, magmatism and salt deposition interact in one compact region.
Visiting Danakil Depression: what travellers from Western Europe should know
- Danakil Depression lies in northern Ethiopia’s Afar region, with the Dallol area approached from towns on the edge of the rift and then by road across the salt plain.
- The terrain around Dallol consists of flat salt surfaces and uneven mineral crusts, together with short ascents on the dome where paths cross brittle deposits and low ridges.
- In summer and many other months the basin experiences very high air temperatures, so any time spent on the exposed salt flats and geothermal field takes place under intense heat.
- English is widely used in Ethiopia alongside local languages, and the national currency is the Ethiopian birr.
- Entry requirements depend on your nationality; UK travellers can check the FCDO travel advice at gov.uk/foreign-travel-advice, Irish travellers the Department of Foreign Affairs at ireland.ie.

Frequently asked questions about Danakil Depression
Where is the Danakil Depression located?
Danakil Depression lies in northern Ethiopia’s Afar region near the border with Eritrea, forming the northern segment of the wider Afar Depression in East Africa.
What should travellers expect when visiting Dallol in the Danakil Depression?
The Dallol area combines wide salt flats, a low-lying rift basin and the colourful hydrothermal field on the Dallol dome, with exposed terrain and high temperatures across much of the year.
What makes the Danakil Depression distinctive compared with other rift landscapes?
Danakil Depression brings together below-sea-level salt plains, thick evaporite sequences, young volcanic features and an active hydrothermal system at Dallol, all concentrated in one compact rift basin.
