Abstract: During the effusive phase of the Stromboli 2007 eruption, the GPS and tilt stations recorded small but significant changes which, for the first time at this volcano, clearly indicated a deflation. We modeled the deflation, inferring a depressurizing vertically elongated source with centre under the volcano edifice about 2.8 km below sea level. The model, whose position is above the magma source region inferred by petrological studies, and the associated rapid deflation suggest a near free pathway for magma ascent from this source to the upper shallow conduit.
