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)Jul 21, 2025 07:20 pm (GMT -4)13 minutes ago4.6115 km0 km - This quake87 km E of Diego de Almagro, Chanaral, Region de Atacama, ChileMain Shock (this quake)MoreMap of aftershocksPrevious quakes in the same area of this earthquakeThe earthquake occurred 39 weeks after a magnitude 4.6 earthquake had hit on Saturday, Oct 19, 2024, at 06:26 pm local time (America/Santiago GMT -4) in 45 km (28 mi) distance to the southeast:Mag. 4.6 earthquake 119 km east of Diego de Almagro - Region de Atacama, Chile - Oct 19, 2024 - The largest quake near the epicenter of this quake during the 10 years before was an event of magnitude 5.3.
