Mat Ala is a low, ~500-m-high shield 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.

The Global Volcanism Program is not aware of any Holocene eruptions from Mat Ala. If this volcano has had large eruptions (VEI >= 4) prior to 10,000 years ago, information might be found on the Mat Ala page in the LaMEVE (Large Magnitude Explosive Volcanic Eruptions) database, a part of the Volcano Global Risk Identification and Analysis Project (VOGRIPA).

The Global Volcanism Program has no synonyms or subfeatures listed for Mat Ala.

The elongated N-S-trending volcanic chain below and to the right of turquoise-colored Lake Afrera consists of the Tat Ali complex at the northern end and the Mat Ala shield volcano at the southern end. Mat Ala contains a small 2.5 x 3.5 km wide caldera visible as a small light-colored dot near the southern end of the chain in this NASA Space Shuttle image. To the SW of Lake Afrera is medium-toned Afderà volcano; Alayta volcano with its extensive dark-colored lava flows is farther to the west.

The following references have all been used during the compilation of data for this volcano, it is not a comprehensive bibliography. Discussion of another volcano or eruption (sometimes far from the one that is the subject of the manuscript) may produce a citation that is not at all apparent from the title.
