Ongoing low-level Strombolian activity and degassing at all Mount Etna summit craters, as reported by INGV-Osservatorio Etneo through mid-April 2026, have kept trader consensus balanced at 50.5% for a VEI 2+ eruption this year, with no confirmed event meeting the threshold of ~0.1 km³ ejecta volume or 1-5 km plume height despite January's effusive Valle del Bove flows and March's brief impulsive explosion. Scientific uncertainties stem from Etna's complex plumbing—recently linked to rare 80 km-deep magma sourcing—making explosive escalation unpredictable amid historical VEI 2+ frequency every 1-3 years during persistent unrest. INGV seismic, deformation, and gas monitoring could signal intensification; weekly Global Volcanism Program updates and potential paroxysms remain key tipping points before year-end.

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.
