Traders see near-even odds across magnitude bins for October 12, 2026, because final authoritative magnitudes from USGS and EMSC remain subject to revision amid multiple moderate events. A 6.1 Mw quake struck near Panama that day at shallow depth along the Nazca-Panama plate boundary, while a 5.5 Mw event occurred in Tonga and a 5.4 Mw quake hit the Mid-Indian Ridge; an initial 5.8 Mw report in Indonesia was later downgraded to 5.3 Mw. Differentiation hinges on precise epicentral calculations, depth adjustments, and moment-magnitude scaling versus body-wave estimates, with historical analogs showing frequent 0.2–0.4 unit revisions in the first 24–48 hours. Upcoming official catalog updates will clarify whether the largest confirmed event falls in the 5.7–6.0 range or exceeds 6.1.
