June 2 2026 Tyrrhenian Sea quake unrelated to Marsili volcano

On 2 June 2026 a magnitude 6.1 (Mw 6.1, ML 6.2) earthquake was recorded in the southern Tyrrhenian Sea. The seismic event originated at a depth of about 250 km within the ionian sub‑duction zone, a region where the Ionian plate descends beneath the Calabrian arc.

The INGV explains that this deep earthquake is geologically separate from the nearby Marsili submarine volcano, which is a shallow volcanic structure rooted in the crust. The distance of several hundred kilometres in depth makes a direct causal link between the quake and any volcanic eruption implausible. Current scientific studies also indicate that such deep tremors do not trigger activity in Marsili or other regional volcanoes. The volcano continues to be monitored through oceanographic campaigns and surveillance systems, but no evidence links the June 2 quake to an increased eruption risk.
