|Region:||Africa and Red Sea|
|Duration of observation:|
|Inferred cause of deformation:|
|Characteristics of deformation:|
Mat Ala has a caldera at its summit. The volcao flanks are cut by numerous north-south trending faults, and fumarolic activity occurs along a fissure southwest of the volcano. Pagli et al. (2014), for the purposes of investigating regional velocity fields, looked at Envisat InSAR data that covered this volcano. They report no deformation.

Mat Ala can be identified in this image by the broad dark eruptive deposits south east of the lake. Its caldera can be seen near the centre of this image. NASA Space Shuttle image S-19-35, 1984.
