英文摘要: From 2006 to spring 2013, Campi Flegrei (CF) caldera, Italy, was mostly uplifting at an increasing rate, particularly high from 2011. We show that the 2011-2013 accelerated uplift and 1980-2010 inflation and deflation phases can be explained by a two-source conceptual model similar to that proposed by Amoruso et al. (2014) (reference model). However, pressurization of the sole thin quasi-horizontal ∼4000m deep source, responsible for large-scale 1980-2010 deformation, can explain the whole 2011-2013 deformation, while activity of the shallower Solfatara hydrothermal source, responsible for residual 1980-2010 deformation, appears constant. These results suggest a predominantly magmatic unrest in 2011-2013. Near-real-time comparison of observations and reference model predictions can provide additional information for short-term eruption forecasting at CF; a similar approach could be followed also in other volcanic environments. Key Points The two sources of 1980-2010 CF deformation satisfy also the 2011-2013 unrest Pressurization of the sole ∼4000m deep source satisfies the whole deformation Injection of magma or magmatic fluids had a predominant role in the unrest © 2014.
