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 2 km2 (1 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)Nov 9, 2025 02:53 am (Universal Time)11 minutes ago4.210 km0 km - This quakeNicobar Islands, India RegionMain 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 28 quakes on average per year in the area near the epicenter of this quake (within 100 km/61 mi):Mag. 6 or higher: 0.12 quakes per year (or 1 quake every 8.5 years)Mag. 5 or higher: 6.7 quakes per yearMag. 4 or higher: 29.1 quakes per yearMag. 3 or higher: 47 quakes per year (or 3.9 quakes per month)Mag. 2 or higher: 47 quakes per year (or 3.9 quakes per month)The area where this quake occurred has a very high level of seismic activity. It has had at least 15 quakes above magnitude 6 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
