July 31, 2023, 21:09:00: Earthquake in Tirreno Meridionale (MARE)

Earthquakes with magnitude 3 felt at 21:09:00 on July 31, 2023.
Place: Tirreno Meridionale (MARE).

Earthquake in Tirreno Meridionale (MARE).

On Monday 31 July 2023 at 21:09:00 an earthquake of magnitude 3 and depth 163.2 km was recorded in Tirreno Meridionale (MARE). 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 occurred at 21:09:00 on July 31, 2023, with epicenter Tirreno Meridionale (MARE), having a depth of 163.2 km is therefore classified as intermediate.

Being of magnitude 3, therefore between 3 and 4, this earthquake is classified as "very light". This type of earthquake is often felt, but it generally causes no harm.
