It is commonly measured on the so-called Modified Mercalli Intensity Scale (MMI) ranging from 1 (not felt) to 10 (extreme shaking), and given in Roman numerals as I,II,...IX, X, and often displayed with color codes ranging from light blue to dark red.Earthquake intensity depends mainly on the magnitude and depth of the quake as well as the distance from the epicenter: The further away, the less shaking intensity occurs.Read more about the MMI scale!Number of reports by intensityShaking intensityNumber of reportsMin-Max distance from epicenter (*)Average distance (*)I: Not felt1899–899 km (558–558 mi)899 km (558 mi)Notes(*) Reports are filtered to exclude those that are likely highly inaccurate or esaggerated.Only reports with latitude/longitude coordinate positions given (1 in total) could be used for geographic statistics.Compare Quake DataData for the same earthquake as reported by different agenciesThe more agencies report about the same quake and post similar data, the more confidence you can have in the data.

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 8 km2 (3 square miles) as a first-order estimate. The length of the rupture zone thus was probably around 5 km (3 mi).[More info]Recorded aftershocks, latest first (0 quake)Jul 26, 2025 11:11 pm (GMT -5)12 minutes ago4.934 km0 km - This quakeSouth Pacific Ocean, 92 km NW of Copiapo, Copiapo, Region de Atacama, ChileMain Shock (this quake)MoreMap of aftershocksPrevious quakes in the same area of this earthquakeThe earthquake occurred 7 weeks after a magnitude 6.4 earthquake had hit on Friday, Jun 6, 2025, at 02:15 pm local time (America/Santiago GMT -3) in 91 km (57 mi) distance to the east:Mag. 6.4 earthquake 58 km north of Copiapo - Region de Atacama, Chile - Jun 6, 2025 - This was also the strongest quake in this area in at least 10 years.
