Campi Flegrei, Bianco (Ingv): “Yesterday’s earthquake was cushioned by the sea”

Napoli – Quiet night at Campi Flegrei after yesterday's big scare: the last shock in chronological order was reported at 19,43 pm and had a magnitude of 1.1.

After the checks by firefighters and civil protection that did not find any significant damage, life has resumed with the usual normality in the Phlegraean municipalities even if the fear remains together with the awareness that we must live with the bradyseism phenomenon.

And speaking of yesterday's earthquake of magnitude 4.6, Francesca Bianco, director of the Volcanoes department of the INGV, the National Institute of Geophysics and Volcanology, explained in an interview with Repubblica that "being located in the sea and at a depth of 3,9 kilometers, greater than usual, it did not cause a particularly violent shaking of the ground".

And then he makes a reflection and an announcement for Punta Pennata in Bacoli: “Small landslides have been recorded on the island of Pennata Tip. This is not the first time that we have witnessed a rock collapse due to the tremors of the Campi Flegrei.

In addition to tourists, these are dangerous events for those who pass underneath with boats. Taking measures is the responsibility of the mayor of Bacoli, not of our institution, which is carrying out inspections with the Coast Guard, but in Stromboli, for example, there is a ban on approaching. It is forbidden to go below a mile from the Sciara del Fuoco”.

“Until the bradyseism ceases, we must expect tremors and seismic swarms”

“We are observing an intensification of bradyseism, which is the engine of these earthquakes. For 20 years, the uplift of the ground at Campi Flegrei has subjected the soil to continuous deformation. The earth's crust is accumulating significant stress and periodically releasing it in the form of earthquakes. Until the bradyseism ceases, we must expect tremors and seismic swarms,” he emphasizes.
