Ma Alalta is trachytic and rhyolitic in composition, containing nested oval-shaped calderas at its summit. Extending northeast and southeast of the stratovolcano are ignimbrite deposits that may be related to the formation of a larger caldera in which Ma Alalta is located.[1]
The northwestern, southeastern and eastern flanks of Ma Alalta have produced youthful basalticlava flows whereas the southern flank has produced recent pantelleriticobsidiandomes and lava flows. One of the domes exhibit fumarolic activity.[1]
