“…These cones and their products (i.e., pillow lavas; Robin et al., 1987) create a larger scale, topographically elevated, wedge‐like morphology whose apex coincides with the VAV summit and the base spreads over the eastern VBAB abyssal plain (Figures 2a and 2c). The morphological difference between the two flanks results from an asymmetric growth of the volcano, although a contribution of past flank collapses can not be excluded (Gallotti et al., 2023).…”

“…The base of the VAV is asymmetrical in E‐W direction since the western side of the basin is about 200 m shallower than the eastern side. The western sector of VAV shows a steep flank with a smooth morphology suggesting the possibility of a flank collapse of the volcano (Gallotti et al., 2023).…”

“…Raw bathymetric data were processed using the software Caris Hips and Sips 8.1 computing an interpolated surface with a cell size resolution of 25 m. High resolution bathymetry of VAV has been integrated with a 200 m gridded data from EMODnet data set (EMODnet Bathymetry Consortium, 2020) obtaining an overview of the VBAB morphology (Figure 1b). The morphometric and geomorphological analysis of VAV has been performed according to Gallotti et al (2023) and the results are reported in Figure 2.…”

Back‐arc basins (BABs) are associated with plate margins where crustal shortening, seafloor spreading, and volcanism coexist. The Vavilov basin (Tyrrhenian Sea) is a Pliocene BAB associated with the Apennine‐Tyrrhenian Sea subduction system and characterized by mantle exhumation. The NNE‐SSW elongated Vavilov seamount represents the easternmost and younger spreading ridge of the Vavilov basin. Here we present results of a morphological and magnetic study of the Vavilov seamount. Our results show that the seamount represents the last stage of the eastward asymmetric opening of the BAB. Its plumbing system consists of a dike swarm emplaced during the reversed Matuyama epoch and a younger shallow reservoir feeding the central and eastern sectors during the normal Brunhes epoch. This evolution is associated with the progressive loading of the edifice due to lava flow emplacement. The asymmetry of the seamount mirrors the asymmetric opening of the Vavilov back‐arc basin.
