The first alarm, as always in these cases, came via social. With many to exchange messages and information about the earthquake that was clearly felt at night in the Campi Flegrei and beyond.
The earthquake alarmed many in Pozzuoli and in several neighborhoods in the western suburbs of Naples. The epicenter is precisely Pozzuoli, the earthquake was located next to the Ingv operations room with magnitude 2.1 to 22.54. There is no damage to property or people.
During the month of November 2020, 225 low-energy earthquakes were recorded in the Campi Flegrei caldera, according to the Vesuvian Observatory website.
In more detail, we read, “during the month of November 2020 in the Campi Flegrei area, 225 low-energy earthquakes were registered with a maximum magnitude = 1.1 ± 0.3. 204 events (91%) had a lower magnitude to 1.0, showing a very low energy level; of 17 events it was not possible to determine the magnitude due to the low amplitude of the signal not clearly distinguishable from the background noise. In total 124 events were located (55% of those registered ) located mainly between Pozzuoli and the Solfatara-Pisciarelli area with depths not exceeding 2.5 km “.
“The ground deformation monitoring networks – continues the Observatory – confirm a radial geometry of the lift centered in the Pozzuoli area with an average speed of about 10 mm / month. The lift recorded in the Rione Terra GPS station ( Rite) as of January 2016 is about 39 cm. Thermographic measurements in the monitored areas show substantially stable temperature trends with a slight decreasing trend. Geochemical parameters confirm the increasing trends observed previously. “
