Two USGS-confirmed earthquakes of magnitude 6.5 or greater have struck within the March 30–April 5 window—a M7.3 event 48 km ENE of Luganville, Vanuatu on March 30 UTC, and a M7.4 quake 126 km WNW of Ternate, Indonesia on April 1 UTC—driving trader consensus to an 88% implied probability for exactly two such events. Subsequent aftershocks in the Indonesia region, including a M6.x on April 2, fell below the 6.5 threshold, with no further qualifying quakes through April 4 despite monitoring along active subduction zones. Global seismicity follows the Gutenberg-Richter frequency-magnitude distribution, averaging fewer than 0.5 M6.5+ events weekly; the final hours of April 5 offer minimal window for additional activity, though inherent tectonic unpredictability leaves slim odds for three or more. USGS real-time feeds will finalize the count post-period.

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 May 31, 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.
