GNGTS 2024 - Atti del 42° Convegno Nazionale

Session 1.2 GNGTS 2024 more on understanding and studying the ongoing phenomenology. The researchers and technicians of the INGV-Osservatorio Vesuviano that is in charge of the monitoring of Campi Flegrei supplied all the data and possible interpretatons to the authorites and to the decision maker. A decrease in the rate of the seismicity and in the velocity of the uplif was recorded in October and November 2023. Other seismically anomalous periods like the one recorded in August- September were recorded during the current unrest of Campi Flegrei. But this last one was characterised by a rate of seismicity and magnitudes that made the authorites and populaton worried and recalled that both the volcanic and seismic risk are to be constantly faced in this area. We will present the data collected by the monitoring system of the INGV-Osservatorio Vesuviano during this last period of the current unrest focusing mainly on the seismicity and ground deformaton.
