Vesuvius remains in a state of quiescence with an official green alert level from the Osservatorio Vesuviano (INGV), as multiparameter monitoring through August 2026 recorded only low-energy seismicity (112 events, mostly below magnitude 1.0), no ground deformation linked to magmatic sources, stable crater temperatures, and a continuing multiyear decline in hydrothermal activity. These baseline conditions, absent any precursors of magma ascent, underpin the market’s 95.4% implied probability against a VEI 1+ eruption before year-end. While the 82-year repose since the 1944 event raises the long-term likelihood of eventual reactivation, current data show no imminent shift. A sudden, undetected phreatic event or rapid escalation in the final months remains theoretically possible given inherent forecasting uncertainty, though dense instrumentation makes such surprises improbable.
