Progressive approach to eruption at Campi Flegrei caldera in southern Italy
Unrest at large calderas rarely ends in eruption, encouraging vulnerable communities to perceive emergency warnings of volcanic activity as false alarms. A classic example is the Campi Flegrei caldera in southern Italy, where three episodes of major uplift since 1950 have raised its central district by about 3 m without an eruption. Individual episodes have conventionally been treated as indepe...
متن کاملMagma transfer at Campi Flegrei caldera (Italy) before the 1538 AD eruption
Calderas are collapse structures related to the emptying of magmatic reservoirs, often associated with large eruptions from long-lived magmatic systems. Understanding how magma is transferred from a magma reservoir to the surface before eruptions is a major challenge. Here we exploit the historical, archaeological and geological record of Campi Flegrei caldera to estimate the surface deformatio...
متن کاملHazard assessment during caldera unrest at the Campi Flegrei, Italy: a contribution from gravity–height gradients
Hazard assessment and risk mitigation at restless calderas is only possible with adequate geophysical monitoring. We show here how detailed long-term microgravity and deformation surveys may contribute to hazard assessment at the Campi Flegrei caldera (CFc) in Italy by evaluating gravity–height change (∆g/∆h) gradients obtained during ground inflation and deflation between 1981 and 2001. Such g...
متن کاملModeling surface deformation observed with synthetic aperture radar interferometry at Campi Flegrei caldera
Satellite radar interferometry of Campi Flegrei caldera, Italy, reveals a pattern of subsidence during the period !993-!998. !nterferograms panning the first half of the observation period (1993-1995) have a lower amplitude and average rate of subsidence than those spanning either the second half (1995-1998) or the entire period (1993-1998), consistent with observations of a slowing down or rev...
متن کاملOperational eruption forecasting at high-risk volcanoes: the case of Campi Flegrei, Naples
High risk volcanic events are commonly preceded by long periods of unrest during which scientists are asked to provide near real-time forecasts. The rarity of such events, inaccessibility of the underground volcanic system, non-linear behaviors, and limited datasets constitute major sources of uncertainty. In order to provide reasoned guidance in the face of uncertainties, monitoring observatio...
