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)May 1, 2026 09:41 pm (San Juan)21 minutes ago4.110 km0 km - This quake37 km SE of Villa San Agustin, Valle Fertil, San Juan Province, ArgentinaMain 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 115 quakes on average per year in the area near the epicenter of this quake (within 100 km/61 mi):Mag. 6 or higher: 0.08 quakes per year (or 1 quake every 12.7 years)Mag. 5 or higher: 1.82 quakes per yearMag. 4 or higher: 8.8 quakes per yearMag. 3 or higher: 47 quakes per year (or 3.9 quakes per month)Mag. 2 or higher: 116 quakes per year (or 9.7 quakes per month)Mag. 1 or higher: 117 quakes per year (or 9.8 quakes per month)The area where this quake occurred has a high level of seismic activity. It has had at least 5 quakes above magnitude 6 since 1970, 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 earthquakeThe earthquake occurred 14 days after a magnitude 4.3 earthquake had hit on Friday, Apr 17, 2026, at 11:38 pm local time (America/Argentina/La Rioja GMT -3) in 100 km (62 mi) distance to the southeast:Mag. 4.3 earthquake Departamento de Rosario Vera Penaloza - La Rioja Province, Argentina - Apr 17, 2026 - The largest quake near the epicenter of this quake during the 10 years before was an event of magnitude 5.2.
