Waw an Namus is an isolated volcano. [1] About 70 kilometres (43 mi) north [18] lie lava flows of basaltic composition and the Haruj volcanic field, [1] of which Waw an Namus is sometimes considered to be a part. These in turn are only two out of several large but little known volcanic fields in the Sahara. [2]

A volcano needs a reservoir of molten magma (e.g. a magma chamber), a conduit to allow magma to rise through the crust, and a vent to allow the magma to escape above the surface as lava. The erupted volcanic material (lava and tephra) that is deposited around the vent is known as a volcanic edifice, typically a volcanic cone or mountain. [2] [22]
Ol Doinyo Lengai is an active volcano in northern Tanzania. It consists of a volcanic cone with two craters, the northern of which has erupted during historical time. Uniquely for volcanoes on Earth, it has erupted natrocarbonatite, [2] an unusually low temperature and highly fluid type of magma. Eruptions in 2007–2008 affected the ...
The word 'malpaís' in Spanish translates to "badland," and this describes the area as being extremely rough and difficult to traverse and unusable for crops.Although a malpaís is often another word for the badlands that form by erosion of sedimentary rocks in the same environment, a malpaís is often associated with such types of lava plain terrain as found in a volcanic field.
