It hit 31 minutes after the mainshock in 0 km (0 mi) distance. When more 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 (1 quake)Jul 27, 2026 08:21 am (GMT +7)16 minutes ago31 minutes after main shock2.44 km0 km (0 mi)N of main shockNorthern Sumatra, IndonesiaMoreJul 27, 2026 07:50 am (Jakarta)48 minutes ago4.03 km0 km - This quakeNorthern Sumatra, IndonesiaMain 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 142 quakes on average per year in the area near the epicenter of this quake (within 100 km/61 mi):Mag. 6 or higher: 0.05 quakes per year (or 1 quake every 18.9 years)Mag. 5 or higher: 1.71 quakes per yearMag. 4 or higher: 14.6 quakes per yearMag. 3 or higher: 64 quakes per year (or 5.4 quakes per month)Mag. 2 or higher: 138 quakes per year (or 11.5 quakes per month)Mag. 1 or higher: 141 quakes per year (or 11.8 quakes per month)The area where this quake occurred has a high level of seismic activity.
