From: The seismicity of Campi Flegrei in the contest of an evolving long term unrest
(A) Map of the Campi Flegrei caldera with epicenters of earthquakes recorded from 2000 to the end of 2020. Black triangles are the seismic stations of the current seismic network. Red line indicates the surficial projections of the slides B and C. (B) Vertical projection of Vp/Vs tomography with the earthquakes of the swarms of 2012, 2015, 2018, 2019 and 2020. To indicate the different swarms, we used different black symbols: 2000—yellow diamonds; 2012—black diamonds; 2015—bordeaux reversed triangles; 2018—black filled circles; 2019—red filled triangles; 2020—hourglasses. Green crosses indicate the relocated earthquakes of the seismic catalogue between 2000 and 2020. (C) Vertical projection of the attenuation tomography with the hypocenters of the five analyzed swarms and the earthquakes of the relocated seismic catalogue (green crosses). Slide A was obtained using the software Surfer 22 (https://www.goldensoftware.com/products/surfer). Slides B and C were built with the software Voxler 3 (http://www.goldensoftware.com/products/voxler).
