Mount Etna's persistent 2026 activity, including multiple summit paroxysms at Voragine, flank lava flows in Valle del Bove, and episodic ash emissions through August and into early September, keeps the market near even odds for a VEI 2+ event. Recent INGV monitoring shows fluctuating volcanic tremor, moderate SO2 flux, and weak ash plumes without sustained high explosivity, while historical patterns favor mostly VEI 0–1 effusive or mild Strombolian phases. Key uncertainties center on whether magma pressurization or new vent dynamics will produce sufficient tephra volume and column height for official GVP classification as VEI 2 before year-end. Traders watch for spikes in seismic swarms, infrasound, or deformation data that could signal escalation, with resolution hinging on the final Smithsonian record.

This market will resolve to "Yes" if the Etna volcano erupts with a Volcanic Explosivity Index (VEI) of 2 or greater between market creation and December 31, 2026, 11:59 PM ET. Otherwise, this market will resolve to “No”.
The primary resolution source will be the Smithsonian Institution Global Volcanism Program (GVP: https://volcano.si.edu/), including the 2026 eruptions page (https://volcano.si.edu/faq/index.cfm?question=eruptionsbyyear&checkyear=2026).
This market will resolve as soon as a qualifying eruption occurs, or once December 31, 2026, 11:59 PM ET has passed and no qualifying eruption has occurred. If there is an ongoing Etna eruption at that time, this market may remain open for an additional 14 calendar days to verify the VEI rating of the ongoing eruption.
If the Smithsonian GVP becomes permanently unavailable, or if an ongoing eruption has not been assigned a VEI rating within 14 calendar days of December 31, 2026, this market may resolve based on a consensus of credible scientific sources, including the U.S. Geological Survey (USGS), national or regional volcanic observatories, or credible reporting of a scientific consensus.
