Noise‐based seismic monitoring of the Campi Flegrei caldera

Geophysical Research Letters, 2017
AbstractThe Campi Flegrei caldera is one of the highest risk volcanic fields worldwide, because of its eruptive history and the large population hosted within the caldera. It experiences bradiseismic crises: sudden uplift with low energetic seismic swarm occurrences. No seismicity is recorded out of these deformation rate changes.

Hydrothermal instability and ground displacement at the Campi Flegrei caldera

Physics of the Earth and Planetary Interiors, 2010
Ground deformation is commonly observed at active volcanoes, where it represents a reliable sign of unrest and a potential precursor of eruptive activity. The source of deformation, however, is not always unequivocally constrained. Magma ascent and differentiation are generally involved, but hydrothermal fluids may play a role, due to thermal expansion

CAMPI FLEGREI CALDERA PUMICES AND SCORIAE

, 2008
[1] The Campi Flegrei (CF) caldera is one of the most dangerous quiescent volcanic systems in the world. Its activity mostly resulted in low-magnitude explosive eruptions, such as that of the Monte Nuovo tuff cone that represents the last eruptive event within the caldera (A.D. 1538).

3D magnetotelluric imaging of a transcrustal magma system beneath the Campi Flegrei caldera, southern Italy

Communications Earth & Environment
Magnetotelluric investigations can reconstruct features within magmatic systems, such as the distribution of melt and fluid and the volcano-tectonic structures.

Critical Transitions at the Campi Flegrei Resurgent Caldera via Multiplatform and Multiparametric Data

Remote Sensing
Understanding how volcanic systems evolve over time is a major challenge due to their complex behaviour and constantly changing conditions. This study explores a novel approach to detecting significant changes in multiparametric signals of volcanic ...

Caldera evolution in Campi Flegrei: the role of fractures and faults

, 2013
Fractures and faults hosted in volcanic rocks in Campi Flegrei were analyzed. The fracture pattern suggests a prevalence of NE-SW and NW-SE directions and secondarily N-S and E-W trends occur. Faults often appear as conjugate structures showing normal kinematics, at places associated with ductile deformation suggesting a syn-eruption deformation ...

b value enlightens different rheological behaviour in Campi Flegrei caldera

Communications Earth & Environment
The Campi Flegrei caldera is one of the most dangerous volcanoes in the world and since 2005 it is in unrest. Here we evaluate the 3D tomography of the b value at the Campi Flegrei volcanic area revealing a very good correlation with the structure of the

Brief communication: Vent opening at Campi Flegrei – clues from dyke propagation patterns [PDF]

Natural Hazards and Earth System Sciences
Forecasting future vent opening position is fundamental for managing volcanic hazards, and is usually based on the spatial density of past vents or other crust weakness indicators.
