“…Embayments have been increasingly used as a tool for estimating magma ascent rates (Befus et al, 2023;Elms et al, 2023;Ferguson et al, 2016;Geshi et al, 2021;Hosseini et al, 2023;Humphreys et al, 2008;Liu et al, 2007;Lloyd et al, 2014;Moussallam et al, 2019;Myers et al, 2016Myers et al, , 2018Myers et al, , 2021Newcombe et al, 2020;Saalfeld et al, 2021;Zuccarello et al, 2022). During magma ascent, the volatile concentrations of a melt decrease due to volatile saturation and exsolution during decompression.…”
