Volcanic-tectonic seismicity at Stromboli (2005–2016)

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 10–12km.
