April 15, 2023, 07:44: Earthquake at Campi Flegrei

Earthquakes with magnitude 1.4 felt at 07:44 on 15 April 2023.
Place: Campi Flegrei.

On Saturday 15 April 2023 at 07:44 an earthquake of magnitude 1.4 and depth 2.4 km was recorded in Campi Flegrei. Further info on the INGV webpage by clicking here.
Based on the depth of the hypocenter, earthquakes are classified into superficial (hypocenter between 0 e 70 and deep), intermediate (Hypocenter between 70 and 300 km deep) and deep (hypocenter between 300 and 720 km deep). The earthquake that occurred at 07:44 on 15 April 2023 with epicenter Campi Flegrei, having a depth of 2.4 km is therefore classified as superficial.
Being of magnitude 1.4, therefore less then 2.0, this earthquake is classified as "micro", as not felt by the population.
