A roadmap for amphibious drilling at the Campi Flegrei caldera: insights from a MagellanPlus workshop [PDF]
Scientific Drilling, 2019 Large calderas are among the Earth's major volcanic features. They are associated with large magma reservoirs and elevated geothermal gradients. Caldera-forming eruptions result from the withdrawal and collapse of the magma chambers and produce large ...

Event trees for eruption forecasting at Campi Flegrei caldera
, 2021 Available studies for Event Trees at the Campi Flegrei caldera are based on the application of the Bayesian Event Tree model for eruption forecasting (BET_EF) and volcanic hazard (BET_VH). In this document we review such studies, which contain full implementation of the probabilistic eruption forecasting and volcanic hazard at Campi Flegrei ...

Frontiers in Earth Science, 2023 Volcanic unrest at large calderas, led by the complex interaction between the degassing of the shallow magma reservoir and the overlying hydrothermal system, occurs at intervals of 10–100 years. Even if only a minority of bradyseismic crises ends with an

GPS time series at Campi Flegrei caldera (2000-2013)
Annals of Geophysics, 2014 The Campi Flegrei caldera is an active volcanic system associated to a high volcanic risk, and represents a well known and peculiar example of ground deformations (bradyseism), characterized by intense uplift periods, followed by subsidence phases with ...

Geosciences, 2022 We report the occurrence of several sand liquefaction structures, such as sand dikes, in the stratigraphic record of the Campi Flegrei volcano, located both inside and outside the caldera. Five sites were analyzed within the caldera and two outside.

The Campi Flegrei caldera: unrest mechanisms and hazards
Geological Society, London, Special Publications, 2006 Abstract In the last four decades, Campi Flegrei caldera has been the world’s most active caldera characterized by intense unrest episodes involving huge ground deformation and seismicity, but, at the time of writing, has not culminated in an eruption.

The dynamics of the Campi Flegrei caldera magma chamber.
, 2022 The Campi Flegrei volcanic system is certainly a remarkable case study for what concerns magma chamber dynamics. In fact, its magmatic and volcanic history appears to have been largely driven by chamber processes like fractional crystallization, magma mixing, and volatile degassing.

Volcanic unrest scenarios and impact assessment at Campi Flegrei caldera, Southern Italy
Journal of Applied Volcanology, 2020 At Campi Flegrei caldera, volcanic unrest hazards during 1982–1984 caused significant building damage and led to the evacuation of over 40,000 residents in the central town of Pozzuoli.

Applied Sciences, 2023 In recent decades, the Campi Flegrei caldera (Italy) showed unrest characterized by increases in seismicity, ground uplift, and hydrothermal activity. Currently, the seismic and hydrothermal phenomena are mostly concentrated in the Solfatara–Pisciarelli ...

Thermally-assisted Magma Emplacement Explains Restless Calderas
Scientific Reports, 2017 Many calderas show repeated unrest over centuries. Though probably induced by magma, this unique behaviour is not understood and its dynamics remains elusive.
