Earthquakes with magnitude 2.1 felt at 21:43 on 15 April 2023.
Place: 1 km N Posta Fibreno (FR).

Terremoto nel Lazio. Terremoto in provincia di Frosinone.

On Saturday 15 April 2023 at 21:43 an earthquake of magnitude 2.1 and depth 7.5 km was recorded in 1 km N Posta Fibreno (FR). 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 21:43 on 15 April 2023 with epicenter 1 km N Posta Fibreno (FR), having a depth of 7.5 km is therefore classified as superficial.
Being of magnitude 2.1, therefore between 2 and 3, this earthquake is classified as "very light". This type of earthquake is not generally felt, but recorded only by seismographs.
