Overview
- The quake was recorded at about 00:12 a.m. local time early Tuesday and was measured at roughly magnitude 6.1–6.2 with depth estimates clustered around 243–265 kilometres by INGV, GFZ and the USGS.
- The epicentre lay in the Tyrrhenian Sea off Calabria and shaking was widely felt across Calabria, Sicily, Campania, Puglia and Basilicata with no confirmed casualties or major structural damage so far.
- Seismologists say deep-focus quakes transmit energy over long distances so they are often widely felt even though the great depth tends to reduce ground shaking at the surface and the risk of severe damage.
- Italian and international agencies and local civil protection teams have begun inspections and continued monitoring, treating the event as a precaution because of the region's active subduction processes.
- The June event follows other notable deep quakes this year, including a March shock off Naples, and researchers are watching for further deep seismic activity and any effects on volcanic systems and slope stability.
