Recent seismic activity has produced at least 15 earthquakes of magnitude 5.5 or greater worldwide between August 17–23, 2026, according to USGS and monitoring reports. This count stems primarily from aftershock sequences in the Flores Sea and nearby Indonesian regions following a M7.7 mainshock on August 15, combined with independent events along Pacific subduction zones, including M6.0+ quakes near Japan and in the Scotia Sea. Such clustering aligns with typical global rates of 10–20 M5.5+ events per week in active tectonic belts, pushing trader consensus toward the >13 outcome at 82.3% implied probability. Upcoming catalog finalization by USGS may confirm exact totals but is unlikely to alter the market resolution.
