Rome CNN —A magnitude 4.0 earthquake struck south of Naples, Italy, on Tuesday, just days after the volcanic region saw its strongest earthquake in 40 years, according to Italy’s National Institute of Geophysics and Volcanology (INGV).
Campi Flegrei, also known as the Phlegraean fields, is a volcanic area that encompasses multiple ancient volcanoes that date back 39,000 years.
Campi Flegrei experiences a seismic phenomenon known as bradyseism, defined by cycles of uplift and gradual lowering of the ground.
The last major eruption of Campi Flegrei was in 1538, which created a new mountain in the bay.
So far in 2023, Campi Flegrei has logged 2,868 earthquakes — 1,118 in August alone.
