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. Mount Etna’s frequent eruptive episodes through 2026, including the ongoing flank activity that began in early January and intensified again in June and August with new vents, lava flows, and explosive summit activity at the Voragine crater, underpin the near-even market odds. Recent August 2026 observations from Italy’s National Institute of Geophysics and Volcanology (INGV) show reduced effusion rates and ash emissions alongside persistently elevated tremor, consistent with typical Etna behavior that often produces VEI 1–2 events but rarely exceeds them in any single phase. Key uncertainties center on precise volume and plume-height measurements needed for VEI classification on the index’s logarithmic scale, plus the inherent variability of Etna’s open-conduit system, where small changes in magma supply or degassing can shift intensity rapidly. Continued INGV monitoring and any new paroxysmal episode with sustained lava fountaining or larger ash columns before year-end could decisively favor a VEI 2+ outcome, while sustained low-level effusive trends would reinforce the slight “No” edge.
