A 6.6-magnitude earthquake struck the Coral Sea near New Caledonia’s Loyalty Islands on September 25, 2026, at approximately 21:23 UTC, with a shallow focal depth of about 10 km and an epicenter roughly 69 km east of Mare Island. This event, recorded by multiple monitoring agencies including EMSC and consistent with USGS data streams, exceeded all other seismic activity that day, such as a 5.3-magnitude quake off Chile. Trader consensus at 100% for 6.1 or greater reflects this confirmed observation from official networks, with negligible probabilities assigned to lower bins. A downward revision of the magnitude below 6.1 by final authoritative catalogs remains the primary scenario that could alter resolution, though preliminary measurements and aftershock patterns strongly support the current assessment.
