WebDec 5, 2024 · Modeling of gravity data suggests the crust beneath rift segments is intruded by dense, likely mafic rock, and that the crust is thinner (e.g., Tiberi et al. 2005; Lewi et al. 2016). Some regions of the Afar Depression have already subsided below sea level, suggesting strongly that seafloor spreading is imminent in Afar (Fig. 1).
