Ringkasan geologi

Mat Ala is a low shield volcano in the southern Tat Ali Range, east of Afderà volcano. A 300-m-deep, 2.5 x 3.5 km wide caldera is found at the summit of the volcano, whose flanks are cut by numerous N-S-trending faults. Mat Ala has been active during the Holocene, and fumarolic activity occurs along a fissure SW of the volcano.
