  abstract = {{W}e analyzed the evolution of volcano-tectonic ({VT}) seismicity and deformation at three basaltic volcanoes ({K}ilauea, {M}auna {L}oa, {P}iton de la {F}ournaise) during phases of magma accumulation. {W}e observed that the {VT} earthquake activity displays an accelerating evolution at the three studied volcanoes during the time of magma accumulation. {A}t the same times, deformation rates recorded at the summit of {K}ilauea and {M}auna {L}oa volcanoes were not accelerating but rather tend to decay. {T}o interpret these observations, we propose a physical model describing the evolution of pressure produced by the accumulation of magma into a reservoir. {T}his variation of pressure is then used to force a simple model of damage, where damage episodes are equivalent to earthquakes. {T}his model leads to an exponential increase of the {VT} activity and to an exponential decay of the deformation rate during accumulation phases. {S}eismicity and deformation data are well fitted by such an exponential model. {T}he time constant, deduced from the exponential increase of the seismicity, is in agreement with the time constant predicted by the model of magma accumulation. {T}his {VT} activity can thus be a direct indication of the accumulation of magma at depth, and therefore can be seen as a long-term precursory phenomenon, at least for the three studied basaltic volcanoes. {U}nfortunately, it does not allow the prediction of the onset of future eruptions, as no diverging point (i.e., critical time) is present in the model.},
