We integrate volcanological, geochemical, petrological and seismic data from the Ma\u2019Alalta volcanic field (MVF) near the western margin of Afar, to show that the MVF is an active magmatic segment. Magmatism in MVF initiated with lava flows and large-volume, caldera-forming ignimbrites from a central edifice. However, the most recent magmatic activity shifted towards mafic lava fields, cinder cones and obsidian-rich silicic domes erupted from vents aligned NNW-SSE, defining a\u2009~\u200935-km-long magmatic segment. Along the same area, a NNW-SSE alignment of earthquakes was recorded by two local seismic networks (2005\u20132009 and 2011\u20132013). The geochemistry of the mafic rocks is similar to those of nearby axial volcanoes. Inferred magma storage depth from mineral geobarometry shows that a shallow, silicic chamber existed at\u2009~\u20095-km depth below the stratovolcano, while a stacked plumbing system with at least three magma storage levels between 9 and 24\u00a0km depth fed the recent basalts. We interpret the wide set of observations from the MVF as evidence that the area is an active magmatic segment, showing that localised axial extension can be heavily offset towards the rift margin.<\/jats:p>","DOI":"10.1007\/s00445-021-01461-4","type":"journal-article","created":{"date-parts":[[2021,5,19]],"date-time":"2021-05-19T09:02:49Z","timestamp":1621414969000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Evidence of active magmatic rifting at the Ma\u2019Alalta volcanic field (Afar, Ethiopia)"],"prefix":"10.1007","volume":"83","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4845-3482","authenticated-orcid":false,"given":"Gianmaria","family":"Tortelli","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anna","family":"Gioncada","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Carolina","family":"Pagli","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mauro","family":"Rosi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Laura","family":"De Dosso","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Derek","family":"Keir","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2021,5,19]]},"reference":[{"key":"1461_CR1","doi-asserted-by":"publisher","first-page":"541","DOI":"10.1007\/s00410-008-0351-8","volume":"157","author":"R Alonso-Perez","year":"2009","unstructured":"Alonso-Perez R, M\u00fcntener O, Ulmer P (2009) Igneous garnet and amphibole fractionation in the roots of island arcs: experimental constraints on andesitic liquids.
