Description:
We model the location, geometry and density of the
source of the recent geological unrest at Campi Flegrei
caldera (Italy) by inverting levelling, trilateration and
gravity measurements collected between 1980 and 1995.
The best fitting source for the 1980–84 inflation is a
horizontal penny-shaped crack with a density 142 to
1115 kg/m3. The source best fitting the deflation period
(1990–95) is a vertical spheroid with density between
902 and 1015 kg/m3. These results exclude the intrusion of
magma, and indicate the migration of fluid to and from the
caldera hydrothermal system as the cause of ground
deformation and consequent unrest.
