Renewed ground uplift at Campi Flegrei caldera (Italy): New insight on magmatic processes and forecast
No full textCampi Flegrei caldera, including the extremely
urbanised city of Naples, is the most risky volcanic area
in the World. The last eruption in the area (1538) occurred
at the end of some decades of ground uplift, superimposed
to secular subsidence. During the last four decades, it
experienced a huge uplift phase, reaching about 3.5 m in
1985, when a subsidence phase started. Recent geodetic
data demonstrate that such a subsidence phase has
terminated, and a new uplift episode started in November
2004, with a low but increasing rate leading to about 0.04 m
of uplift till the end of October 2006. A new indicator, based
on the monitoring of maximum horizontal to vertical
displacement ratio with continuous GPS, indicates that
this uplift is likely to be associated with input of magmatic
fluids from a shallow magma chamber. The method is
promising to monitor magma intrusion processes, at this and
other volcanoes. Citation: Troise, C., G. De Natale, F. Pingue,
