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)Aug 17, 2026 12:06 pm (GMT +9)28 minutes ago4.110 km0 km - This quakePhilippine Sea, 60 km SE of Miyazaki, Miyazaki, JapanMain Shock (this quake)MoreMap of aftershocksEarthquake statisticsAverage number of earthquakesBased on data from the past 26 years and our earthquake archive back to 1900, there are about 1,300 quakes on average per year in the area near the epicenter of this quake (within 100 km/61 mi):Mag. 7 or higher: 0.07 quakes per year (or 1 quake every 14.1 years)Mag. 6 or higher: 0.37 quakes per year (or 1 quake every 2.7 years)Mag. 5 or higher: 1.65 quakes per yearMag. 4 or higher: 15.7 quakes per yearMag. 3 or higher: 62 quakes per year (or 5.2 quakes per month)Mag. 2 or higher: 183 quakes per year (or 15.3 quakes per month)Mag. 1 or higher: 677 quakes per year (or 56 quakes per month)The area where this quake occurred has a very high level of seismic activity. It has had at least 9 quakes above magnitude 7 since 1900, which suggests that larger earthquakes of this size occur infrequently, probably on average approximately every 10 to 15 years.Number of quakes per yearPrevious quakes in the same area of this earthquake
