Mount Vesuvius remains in a quiescent state with green alert level and persistently low seismicity, showing no measurable ground deformation, elevated gas emissions, or other precursory signals through mid-2026 per INGV monitoring. The volcano has been in repose since its 1944 eruption, consistent with historical cycles of long dormancy between VEI 1+ events. Traders assign just a 5% implied probability of a VEI 1+ event this year because current geophysical data show no precursors that could produce an eruption before year-end. While sudden unrest cannot be ruled out, resolution would require an explosive event meeting the VEI threshold within the calendar year, a low-likelihood outcome given the absence of precursory signals.
