It takes normally up to a few hours until earthquake parameters are calculated with near-optimum precision.MagDepthTime GMT2025-09-25EpicenterAgency5.310 km6.2 mi(*)23:22:38.67Off 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 208 quakes on average per year in the area near the epicenter of this quake (within 100 km/61 mi):Mag. 7 or higher: 0.02 quakes per year (or 1 quake every 41.7 years)Mag. 6 or higher: 0.47 quakes per year (or 1 quake every 2.1 years)Mag. 5 or higher: 8.6 quakes per yearMag. 4 or higher: 117 quakes per year (or 9.7 quakes per month)Mag. 3 or higher: 169 quakes per year (or 14.1 quakes per month)Mag. 2 or higher: 190 quakes per year (or 15.9 quakes per month)Mag. 1 or higher: 192 quakes per year (or 16 quakes per month)The area where this quake occurred has a very high level of seismic activity. It has had at least 3 quakes above magnitude 7 since 1900, which suggests that larger earthquakes of this size occur infrequently, probably on average approximately every 40 to 45 years.Number of quakes per yearPrevious quakes in the same area of this earthquake
