Campi Flegrei, the lifting of the soil in particular in the Rione Terra area in Pozzuoli, continues unabated.
According to data fromVesuvian Observatorysince January 2023 the ground has risen by approximately 25.5 centimeters at the Rione Terra GNSS station, of which 7.5 cm in the first five months of 2024.
Compared to the last week, the lift has increased by 0.5 centimeters. In recent months, the pace of lifting is acceleratedaveraging 10 millimeters per month from January to April and 20 millimeters per month from mid-April.
Two significant lifting episodes
Between 9 and 16 April, two distinct episodes of ground lifting affected the area: the first of approximately 1 centimeter (9-10 April) and the second of 0.5 centimeters (April 15-16).
Seismic activity is also increasing. Between May 13th and 19th they were recorded 126 earthquakesof which 33 concentrated in two seismic swarms: one on May 15th in the area of Solfatara and the Gulf of Pozzuoli, the other on May 18th inarea of Bagnoli and Solfatara Pisciarelli.
No imminent danger
Despite the increase in uplift and seismic activity, the Vesuvian Observatory points out that at the moment “there are no elements that suggest significant short-term developments”. The data relating to the seismic swarm that began on the evening of May 20, with the strong shock of magnitude 4.4, will be the subject of a subsequent bulletin.
Constant monitoring
The situation in the Campi Flegrei is subjected to constant monitoring by the Vesuvian Observatory, which regularly updates the surveillance bulletins. Local authorities invite the population to stay informed and to follow the instructions of the authorities in the event of an alert.
