Recent USGS monitoring shows a 7.8-magnitude mainshock off southern Mindanao on June 7–8, 2026, followed by a 6.5 aftershock in the Celebes Sea region the next day, illustrating how subduction-zone sequences can briefly raise M6.5+ counts. Globally, roughly 140–150 magnitude 6–6.9 events occur annually, producing a low average weekly rate near one, with most clustered along convergent margins. No additional M6.5+ events have been cataloged through June 14, and current strain indicators and model runs show no active foreshock swarms or unusual seismic unrest on other major faults. Trader consensus heavily weighting zero or one event for the June 8–14 window aligns with this baseline and the rapid decay typical of aftershock sequences, with upcoming USGS catalog updates the next key data point.

The resolution source for this market is the United States Geological Survey (USGS) Earthquake Hazards Program (https://earthquake.usgs.gov/earthquakes/browse/significant.php#sigdef).
If an earthquake of substantial size has occurred within this market's timeframe but not yet appeared on the resolution source, this market may remain open until June 30, 2026, 11:59 PM ET, or until the earthquake in question otherwise appears on the resolution source. If such an earthquake has not appeared on the resolution source by that date, another credible resolution source will be used.
This market may not resolve until the timeframe of this market has concluded. If a qualifying earthquake has been recorded on the final day, this market may remain open for 24 hours to allow for revisions to the recorded magnitude. After 24 hours, this market will resolve according to the latest provided data.
