mayor allowed the project to go forward. A Reuters article emphasized that the area could produce a "super volcano" that might kill millions. A study from the Istituto Nazionale di Geofisica e Vulcanologia shows that the volcanic unrest of the Campi Flegrei caldera from January 2012 to June 2013 was characterised by rapid ground uplift of about , with a peak rate of about per month during December 2012. It adds that from 1985 to 2011 the dynamics of ground uplift were mostly linked to the caldera's hydrothermal system, and that this relation broke down in 2012. The driving mechanism of the ground uplift changed to periodical emplacement of magma within a flat sill-shaped magmatic reservoir about in depth, south from the port of Pozzuoli. In December 2016, activity became so high that an eruption was feared. In May 2017 a new study by University College London and the Vesuvius Observatory published in Nature Communications revealed that an eruption might be closer than previously thought. The study found that the geographical unrest since the 1950s has a cumulative effect, causing a build-up of energy in the crust and making the volcano more susceptible to eruption. On 21 August 2017 there was a magnitude 4 earthquake on the western edge of the Campi Flegrei area. Two people were killed and many more people injured in Casamicciola on the northern coast of the island of Ischia, which is south of the epicentre. A February 2020 status report indicated that inflation around Pozzuoli continues at steady rates with a maximum average of 0.7 cm per month since July 2017. Gas emissions and fumarole temperatures did not change significantly. On Sunday April 26, 2020, a moderate earthquake swarm hit Campi Flegrei caldera, which included about 34 earthquakes ranging between magnitude 0 and magnitude 3.1 with the swarm centered around the port city of Pozzuoli. The strongest quake in the Earthquake sequence was a magnitude 3.1, which is the strongest earthquake in the caldera going back to the last major period of unrest and rapid uplift in 1982-1984. However, no new fumaroles were reported. In its weekly bulletin of April 6 2021, the Italian National Institute of Geophysics and Volcanology (INGV) reported that the Rione Terra (RITE) GPS tiltmeter had an average uplift rate of 13mm per month +/- 2mm. The strongest quake since March 29 2021 had been of magnitude 2.2, and the RITE
