  abstract = {{I}t is intuitive to think that an earthquake near a volcano could disrupt its equilibrium and potentially trigger an eruption. {B}ut this cause-and-effect link is far from obvious for active volcanoes with an unknown internal stress state and the complexity of its magma-hydrothermal processes. {T}his phenomenon is clearer in continentaloceanic subduction zones where volcanoes generally have closed-vent systems, differentiated high-viscosity magma, and active hydrothermal systems. {T}his phenomenon is less well known in oceanic-oceanic subduction zones, where volcanoes often have open-vent systems, low-viscosity mafic magma, and hypothetic hydrothermal systems. {T}he {V}anuatu oceanic-oceanic subduction is an ideal zone to perform such study due to a high-seismic rate and volcanoes with different characteristics. {T}he {V}anuatu volcanoes display both open- and closed-vent systems, low and relatively high viscosity magma that enhance different types of volcanic activities (such as lava lakes, strombolian eruptions, high-eruptive columns, phreatic activity), and potential active hydrothermal systems. {W}e compiled and identified sixty-nine cases of earthquakes potentially triggering volcanic activities on {V}anuatu volcanoes from 1913 to 2018. {O}ur findings indicate that the triggered volcanic responses occur coseismically or shortly (at most 2 -3 months later) after the earthquake, that the activated volcanoes are mainly located at near-field distances of the potentially triggering earthquake, implying a strong influence of static stress changes. {U}sing the value of the seismic density energy, we suggest that the mechanism of the {V}anuatu volcanic responses is due to changes of the permeability within active hydrothermal systems at {L}opevi and {A}mbrym volcanoes in addition to the well-established ones, at {A}mbae, {G}aret, and {Y}asur volcanoes.},
