Mount Etna has maintained persistent eruptive activity throughout 2026, beginning with flank lava flows in January and featuring repeated Strombolian explosions, ash emissions, and fissure-fed effusive phases into August, including a 7 km plume from Voragine crater in late July and ongoing flows in Valle del Bove. This history drives the near-even market odds, with traders weighing whether episodes have already met or will reach VEI 2 criteria—defined by roughly 0.001–0.01 km³ of tephra and plumes typically exceeding 1 km—versus remaining at lower-intensity VEI 1 levels. Key uncertainties include precise post-event volume estimates from INGV seismic, deformation, and satellite data, plus variable plume heights influenced by wind and magma supply. Continued flank or summit activity through year-end, or new INGV alert escalations and quantitative ash-fall measurements, could shift consensus decisively before resolution.

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.
