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 6 km2 (2 square miles) as a first-order estimate. The length of the rupture zone thus was probably around 4 km (3 mi).[More info]Recorded aftershocks, latest first (0 quake)Oct 4, 2026 01:51 am (GMT +12)22 minutes ago4.8482 km0 km - This quakeSouth Pacific Ocean, 177 km NW of Raoul Island, New ZealandMain Shock (this quake)MoreMap of aftershocksEarthquake statisticsAverage number of earthquakesBased on data from the past 56 years and our earthquake archive back to 1900, there are about 16 quakes on average per year in the area near the epicenter of this quake (within 100 km/61 mi):Mag. 6 or higher: 0.1 quakes per year (or 1 quake every 10.5 years)Mag. 5 or higher: 1.21 quakes per yearMag. 4 or higher: 13.4 quakes per yearMag. 3 or higher: 22.2 quakes per yearMag. 2 or higher: 22.5 quakes per yearThe area where this quake occurred has a very high level of seismic activity. It has had at least 12 quakes above magnitude 6 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
