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 3 km2 (1 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 09:53 am (Universal Time)13 minutes ago4.5106 km0 km - This quakeProvincia de Antofagasta, 56 km SW of Calama, Provincia de El Loa, Region de Antofagasta, ChileMain Shock (this quake)MoreMap of aftershocksPrevious quakes in the same area of this earthquakeThe earthquake occurred 21 hours after a magnitude 4.5 earthquake had hit on Sunday, Jul 20, 2025, at 08:36 am (GMT -4 local time) in 23 km (14 mi) distance to the east:Mag. 4.5 earthquake Provincia de Antofagasta - Region de Antofagasta, Chile - The largest quake near the epicenter of this quake during the 10 years before was an event of magnitude 7.4.
