Abstract: The seismicity of Stromboli comprises explosion-quakes, volcanic tremor and volcano-tectonic (VT) events.We applied the double-difference approach of Waldhauser and Ellsworth (2000) on 42 VT events recorded during 2005–2016 in order to improve their standard locations. This approach has allowed to cluster hypocentres in two seismogenic sectors (G1 and G2), respectively, located inside and south of Stromboli at depths of 3.5–6 and 10–12 km. The seismicity belonging to G1 is located between the deep and intermediate magma storages of Stromboli and seems to precede the 2007 and 2014 effusive eruptions. This suggests that faulting episodes occur as a response to local stress linked to the pressurization of the magmatic system caused by magma ascent.
