The Global Volcanism Program has no activity reports for Ma Alalta.
The Global Volcanism Program has no Weekly Reports available for Ma Alalta.
The Global Volcanism Program has no Bulletin Reports available for Ma Alalta.
The Global Volcanism Program is not aware of any Holocene eruptions from Ma Alalta. If this volcano has had large eruptions (VEI >= 4) prior to 10,000 years ago, information might be found on the Ma Alalta page in the LaMEVE (Large Magnitude Explosive Volcanic Eruptions) database, a part of the Volcano Global Risk Identification and Analysis Project (VOGRIPA).
This compilation of synonyms and subsidiary features may not be comprehensive. Features are organized into four major categories: Cones, Craters, Domes, and Thermal Features. Synonyms of features appear indented below the primary name. In some cases additional feature type, elevation, or location details are provided.
|Gar-uli | Pierre Pruvost|
|Ma Alalta volcano (center), also known as Pierre Pruvost, is an 1815-m-high stratovolcano located well to the west of the Danakil depression. A large trachytic and rhyolitic stratovolcano at the center of the Ma Alalta complex contains nested oval-shaped summit calderas, 6 km and 4 km wide in the long direction. Young basaltic lava flows were erupted on the NW, SE, and eastern flanks of the volcano, and young pantelleritic obsidian domes and lava flows were erupted on the volcano's southern flank.

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.

|Large Eruptions of Ma Alalta||Information about large Quaternary eruptions (VEI >= 4) is cataloged in the Large Magnitude Explosive Volcanic Eruptions (LaMEVE) database of the Volcano Global Risk Identification and Analysis Project (VOGRIPA).|
|WOVOdat||WOVOdat is a database of volcanic unrest; instrumentally and visually recorded changes in seismicity, ground deformation, gas emission, and other parameters from their normal baselines. It is sponsored by the World Organization of Volcano Observatories (WOVO) and presently hosted at the Earth Observatory of Singapore.|
|EarthChem||EarthChem develops and maintains databases, software, and services that support the preservation, discovery, access and analysis of geochemical data, and facilitate their integration with the broad array of other available earth science parameters. EarthChem is operated by a joint team of disciplinary scientists, data scientists, data managers and information technology developers who are part of the NSF-funded data facility Integrated Earth Data Applications (IEDA). IEDA is a collaborative effort of EarthChem and the Marine Geoscience Data System (MGDS).|
