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. If no earthquake data for this market's timeframe has been published on the resolution source by 48 hours after the market's closing time, this market will resolve to the lowest bracket.
