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)Mar 20, 2026 06:57 am (GMT +3)27 minutes ago4.210 km0 km - This quake82 km NE of Mamoudzou, Mamoudzou, MayotteMain 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 1,700 quakes on average per year in the area near the epicenter of this quake (within 100 km/61 mi):Mag. 5 or higher: 0.61 quakes per year (or 1 quake every 1.6 years)Mag. 4 or higher: 32.5 quakes per year (or 2.7 quakes per month)Mag. 3 or higher: 109 quakes per year (or 9.1 quakes per month)Mag. 2 or higher: 651 quakes per year (or 54 quakes per month)Mag. 1 or higher: 1,600 quakes per year (or 4.3 quakes per day)The area where this quake occurred has a high level of seismic activity. It has had at least 16 quakes above magnitude 5 since 2000, which suggests that larger earthquakes of this size occur infrequently, probably on average approximately every 1 to 5 years.Number of quakes per yearPrevious quakes in the same area of this earthquakeThe earthquake occurred 9 days after a magnitude 4.4 earthquake had hit on Tuesday, Mar 10, 2026, at 07:42 pm (GMT +3 local time) in 92 km (57 mi) distance to the southeast:Mag. 4.4 earthquake 79 km east of Mamoudzou - Mamoudzou, Mayotte - Mar 10, 2026 - The strongest-ever (since 1900) recorded quake in this area measured magnitude 5.9.
