It has had at least 2 quakes above magnitude 7 since 1900, which suggests that larger earthquakes of this size occur infrequently, probably on average approximately every 60 to 65 years.Number of quakes per yearPrevious quakes in the same area of this earthquakeThe earthquake occurred 2 hours and 27 minutes after a magnitude 5.1 earthquake had hit on Thursday, Jul 31, 2025, at 10:27 am (GMT +11 local time) in 89 km (55 mi) distance to the northeast:Mag. 5.1 earthquake North Pacific Ocean - Kamchatka, Russia - The largest quake near the epicenter of this quake during the 10 years before was an event of magnitude 7.4.
