People likely experienced very weak shaking there. Several smaller towns and villages are located closer to the epicenter and might have experienced stronger shaking.

When aftershocks are detected, we will update this section.What are aftershocks?Larger earthquakes (above magnitude 5 or so) such as this one are usually followed by smaller ones known as aftershocks that occur in the same area during the days, weeks, months or even years after the main shock.[More info]What about this quake?Based on its magnitude, the fault that was active during the quake likely ruptured beneath a surface area of approximately 1 km2 (0 square miles) as a first-order estimate. The length of the rupture zone thus was probably around 2 km (1 mi).[More info]Recorded aftershocks, latest first (0 quake)Oct 10, 2025 09:25 pm (GMT +9)10 minutes ago4.060 km0 km - This quakeNear East Coast of Honshu, JapanMain Shock (this quake)MoreMap of aftershocksEarthquake statisticsAverage number of earthquakesBased on data from the past 25 years and our earthquake archive back to 1900, there are about 7,800 quakes on average per year in the area near the epicenter of this quake (within 100 km/61 mi):Mag. 7 or higher: 0.14 quakes per year (or 1 quake every 7.1 years)Mag. 6 or higher: 1.89 quakes per yearMag. 5 or higher: 14.4 quakes per yearMag. 4 or higher: 100 quakes per year (or 8.3 quakes per month)Mag. 3 or higher: 451 quakes per year (or 37.6 quakes per month)Mag. 2 or higher: 1,600 quakes per year (or 4.4 quakes per day)Mag. 1 or higher: 6,300 quakes per year (or 17.1 quakes per day)The area where this quake occurred has a very high level of seismic activity. It has had at least 18 quakes above magnitude 7 since 1900, which suggests that larger earthquakes of this size occur infrequently, probably on average approximately every 5 to 10 years.Number of quakes per yearPrevious quakes in the same area of this earthquake
