On Wednesday 8 February 2023 at 21:51:00 an earthquake of magnitude 3.5 and depth 11.3 km was recorded in 1 km SW Siena (SI). 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 21:51:00 on February 8, 2023, with epicenter 1 km SW Siena (SI), having a depth of 11.3 km is therefore classified as superficial.

Being of magnitude 3.5, 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.
