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 4 km2 (2 square miles) as a first-order estimate. The length of the rupture zone thus was probably around 3 km (2 mi).[More info]Recorded aftershocks, latest first (0 quake)Aug 8, 2026 09:44 am (Salta)25 minutes ago4.6164 km0 km - This quakeDepartamento de Los Andes, 172 km W of Salta, Departamento Capital, Salta Province, ArgentinaMain Shock (this quake)MoreMap of aftershocksPrevious quakes in the same area of this earthquakeThe earthquake occurred 5 days after a magnitude 4.6 earthquake had hit on Monday, Aug 3, 2026, at 07:55 am local time (America/Argentina/Salta GMT -3) in 14 km (9 mi) distance to the southwest:Mag. 4.6 earthquake Departamento de Los Andes - Salta Province, Argentina -The largest quake near the epicenter of this quake during the 10 years before was an event of magnitude 7.4.
