Phlegraean Fields
The area of Phlegraean Fields (Campi Flegrei), near Naples, is a collapsed caldera, namely a volcanic area formed by several volcanic edifices, which includes the Solfatara volcano, well known for its fumaroles. Campi Flegrei area is especially noted for bradyseismic uplift and subsidence. The inflation and deflation of this caldera is especially well documented due to its seaside location and a long history of habitation and construction in the area.
