It has had at least 4 quakes above magnitude 7 since 1900, which suggests that larger earthquakes of this size occur infrequently, probably on average approximately every 30 to 35 years.Number of quakes per yearPrevious quakes in the same area of this earthquakeThe earthquake occurred 1 hour and 29 minutes after a magnitude 5.3 earthquake had hit on Thursday, Jul 31, 2025, at 01:38 pm (GMT +11 local time) in 65 km (40 mi) distance to the northeast:Mag. 5.3 earthquake 162 km SE of Vilyuchinsk - Russia - The largest quake near the epicenter of this quake during the 10 years before was an event of magnitude 8.8.
