  abstract = {{T}he nucleation of gas bubbles in magmas is fundamental to controlling the dynamics of volcanic eruptions. {I}n this study, we addressed nucleation in a volatile-saturated liquid triggered by viscous shear, which is ubiquitous in volcanic environments. {B}y combining laboratory experiments, theoretical analysis, and numerical simulations, we investigated the conditions under which the mechanical energy associated with shearing favors the formation and growth of gas molecule nuclei in a liquid supersaturated with volatiles. {O}ur results reveal that the critical shear stress for nucleation decreases as the volatile supersaturation increases. {D}imensional analysis applied to natural systems shows that shear-induced nucleation is likely to occur in volcanic conduits, which has implications for magma degassing processes and eruptive styles.},
