Title: Ground deformations in the Island of Pantelleria (Italy): Insights into the dynamic of the current intereruptive period
Title of journal: Journal of Geophysical Research
Series/Report no.: /112(2007)
Publisher: American Geophysical Union
Issue Date: 30-Nov-2007
DOI: 10.1029/2006JB004781
Keywords: Pantelleria
Abstract: The Island of Pantelleria, located between the coasts of Sicily (Italy) and Tunisia, is deforming due to volcanic and tectonic activity. Here we use electro-optical distance meter, leveling, GPS, and differential interferometry synthetic aperture radar data to constrain the inter-eruptive deformation pattern. We observe subsidence affecting the main caldera of Pantelleria, in the central southern sector of the island. Subsidence is mainly related to hydrothermal cooling and/or fluid withdrawal from a shallow (4 km below sea level) magma chamber located beneath the caldera. The relationships between the caldera area and the remnant part of the island are also investigated through a review of petrographic, geochemical, and structural data.
