It takes normally up to a few hours until earthquake parameters are calculated with near-optimum precision.MagDepthTime GMT2025-08-7EpicenterAgency4.8310 km6.2 mi(*)04:22:20.17Off East Coast of KamchatkaGFZ (German Research Centre for Geosciences)Notes:(*) A depth given as 10 km often means that the the depth of the quake could be not determined with sufficient accuracy.Earthquake statisticsAverage number of earthquakesBased on data from the past 25 years and our earthquake archive back to 1900, there are about 115 quakes on average per year in the area near the epicenter of this quake (within 100 km/61 mi):Mag. 7 or higher: 0.05 quakes per year (or 1 quake every 20.8 years)Mag. 6 or higher: 0.6 quakes per year (or 1 quake every 1.7 years)Mag. 5 or higher: 5.1 quakes per yearMag. 4 or higher: 41 quakes per year (or 3.4 quakes per month)Mag. 3 or higher: 86 quakes per year (or 7.1 quakes per month)Mag. 2 or higher: 107 quakes per year (or 8.9 quakes per month)Mag. 1 or higher: 109 quakes per year (or 9.1 quakes per month)The area where this quake occurred has a very high level of seismic activity. It has had at least 6 quakes above magnitude 7 since 1900, which suggests that larger earthquakes of this size occur infrequently, probably on average approximately every 20 to 25 years.Number of quakes per yearPrevious quakes in the same area of this earthquake
