High precision locations of long-period events at La Fossa Crater (Vulcano Island, Italy)
Annals of Geophysics, 2009 Since the last eruption in 1888-90, the volcanic activity on Vulcano Island (Aeolian Archipelago, Italy) has been limited to fumarolic degassing. Fumaroles are mainly concentred at the active cone of La Fossa in the northern sector of the island and are ...

Recorded displacements in a landslide slope due to regional and teleseismic earthquakes [PDF]
, 2015 Regional and teleseismic earthquakes can induce displacements along joints in a landslideinvolved rocky slope in Central Italy. The rarity of these effects is due to specific physical properties of the seismic signals associated with: (i) the energy ...

Subglacial volcano monitoring with fibre-optic sensing: Grímsvötn, Iceland
Volcanica, 2023 We present a distributed acoustic sensing (DAS) experiment at Grímsvötn, Iceland. This is intended to investigate volcano-microseismicity at Grímsvötn specifically, and to assess the suitability of DAS as a subglacial volcano monitoring tool in general ...
