Trader sentiment heavily favors zero VEI ≥4 eruptions in 2026 (64% implied probability) due to the low global baseline rate of such events—historically averaging roughly 0.5–1 per year based on Smithsonian and USGS records—combined with no confirmed large explosive episodes through July. VEI 4 requires at least 0.1 km³ of tephra and plume heights exceeding 10 km, criteria met only by Plinian or sub-Plinian events that remain infrequent even at frequently active systems. Current monitoring from agencies like the USGS and PHIVOLCS shows mostly lower-level unrest or smaller ongoing eruptions (e.g., Lewotobi, Mayon) without precursors indicating rapid escalation to VEI 4 thresholds. With roughly five months remaining, the market assigns only 18.5% odds to exactly one such eruption, reflecting both the statistical rarity and lack of near-term indicators from official alert networks.
