Continuous GPS monitoring of Lipari and Vulcano islands started in April 1995, when a four-site permanent GPS network (VVLC, VCSP, LOSV and VGPL) was installed by the International Institute of Volcanology, now Istituto Nazionale di Geofisica e Vulcanologia (INGV-CT; Mattia et al., 2008).

The tectonic deformation of the Lipari–Vulcano complex is presented in Mattia et al. (2008), with the analysis of 10 years (1996–2006) of GPS data from both three permanent and 13 non-permanent stations.

The authors present a kinematic deformation model on the basis of the geodetically estimated velocities of the Lipari–Vulcano complex. They show that the observed deformation pattern can be described by a combination of (1) the main N–S regional compression and (2) a NNE–SSW compression with a small right-lateral strike slip component acting along a tectonic structure trending N°40W between the two islands (Mattia et al., 2008).

Bonaccorso (2002) use trilateration geodetic network between the islands of Vulcano and Lipari to show that between 1978 and 1998 deformation in this regions is due to E–W trending extension and a N–S contraction at a regional scale.

Solaro et al. (2014) present preliminary results on deformation field on Lipari, Vulcano and Stromboli islands using COSMO-SkyMed (CSK) data both from ascending and descending orbits, generating time series extending from 2008 to 2013. They show that Lipari is deforming due to non-volcanic processes such as gravitational instability phenomena mainly located in correspondence of coastal cliffs (Solaro et al., 2014). 

The Instituto Nazionale di Geofisica e Vulcanologia (INGV) monitors active volcanoes in Italy via multiparametric systems. In particular, the INGV Observatories Vesuviano and Etneo are responsible for the surveillance of the Campi Flegrei, Vesuvius, Ischia, Etna, Stromboli, Panarea, Lipari, Vulcano and Pantelleria volcanoes (Brown et al., 2008).
