- The determining value is the USGS-reported magnitude displayed at Expiration, preferentially moment magnitude (Mw) and otherwise the primary magnitude type reported by USGS. If multiple earthquakes tie for the highest magnitude, all tied earthquakes count. If USGS ComCat is unavailable at Expiration, settlement may be delayed under the Contract contingencies.
