“…There is extensive evidence of the dependence of seismic attenuation and absorption on thermal variations at the mantle, crustal, and volcano scales (Abers et al., 2006; Cammarano & Romanowicz, 2008; De Lorenzo et al., 2001), with high thermal potential the most likely explanation for absorption increases at locations Aa1‐Aa3. On the other hand, geochemical variations caused by different fluid compositions and saturation levels can equally change attenuation in space (Amoroso et al., 2017; De Landro et al., 2019), especially within an active hydrothermal system (Di Martino et al., 2021). The NE‐SW and NNE‐SSW high‐absorption trends correspond to the measured variations in Mn and As, respectively (Rey et al., 2002; Somoza et al., 2004) (Figure 3d).…”
