So far, we have received 2 reports for this quake from Chile. The quake was reported to have been felt in up to approx. 130 km (81 mi) distance, with isolated cases to have felt the quake even 135 km (84 mi) away.Most reports came from Arica, a city with more than 220,000 inhabitants in 133 km (82 mi) distance northwest of the epicenter, Chile. Further below is a list of places where most people reported this quake.This section is being updated as new data comes in.User reports estimate the perceived ground shaking intensity according to the MMI (Modified Mercalli Intensity) scale.Translatearica (134.7 km NNW of epicenter) [Map] / Weak shaking (MMI III)129.7 km NNW of epicenter [Map] / Light shaking (MMI IV) (reported through our app)List of cities/places with most reportsPlaceDistance from epicenterAverage reported Shaking IntensityNr. of reportsArica, Region de Arica y Parinacota, Chile(Pop.: 221,364)133 km (82 mi)NW of epicenterIII: Weak shaking1Note: Only reports with latitude/longitude coordinate positions given (2 in total) could be used for statistics.What is Intensity and the Mercalli Intensity Scale?The amount of shaking that occurs on the surface due to an earthquake is called the intensity. 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 (*)III: Weak shaking1135–135 km (84–84 mi)135 km (84 mi)IV: Light shaking1130–130 km (80–80 mi)130 km (80 mi)Notes(*) Reports are filtered to exclude those that are likely highly inaccurate or esaggerated.Only reports with latitude/longitude coordinate positions given (2 in total) could be used for geographic statistics.I didn't feel itI felt this quakeIf you were near the epicenter and felt it, please share your experience and submit a short "I felt it" report! Other users would love to hear about it!If you did NOT feel the quake although you were in the area, please report it as well! Your contribution is valuable to earthquake science and seismic hazard analysis.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 13 km2 (5 square miles) as a first-order estimate. The length of the rupture zone thus was probably around 6 km (4 mi).[More info]Recorded aftershocks, latest first (0 quake)Sep 28, 2025 05:53 pm (Santiago)13 minutes ago - felt5.18 km0 km - This quakeProvincia de Iquique, Tarapacá, 133 km SE of Arica, Arica, Region de Arica y Parinacota, ChileMain Shock (this quake)MoreMap of aftershocksEarthquake statisticsAverage number of earthquakesBased on data from the past 25 years and our earthquake archive back to 1900, there are about 404 quakes on average per year in the area near the epicenter of this quake (within 100 km/61 mi):Mag. 7 or higher: 0.03 quakes per year (or 1 quake every 31.3 years)Mag. 6 or higher: 0.2 quakes per year (or 1 quake every 5 years)Mag. 5 or higher: 3.7 quakes per yearMag. 4 or higher: 37.9 quakes per year (or 3.2 quakes per month)Mag. 3 or higher: 184 quakes per year (or 15.3 quakes per month)Mag. 2 or higher: 402 quakes per year (or 33.5 quakes per month)Mag. 1 or higher: 403 quakes per year (or 33.6 quakes per month)The area where this quake occurred has a very high level of seismic activity. It has had at least 4 quakes above magnitude 7 since 1900, which suggests that larger earthquakes of this size occur infrequently, probably on average approximately every 30 to 35 years.Number of quakes per yearPrevious quakes in the same area of this earthquakeThe earthquake occurred 3 days after a magnitude 5.3 earthquake had hit on Thursday, Sep 25, 2025, at 03:11 pm local time (America/Santiago GMT -3) in 51 km (31 mi) distance to the east:Mag. 5.3 earthquake 118 km northeast of Iquique - Tarapacá, Chile - The largest quake near the epicenter of this quake during the 10 years before was an event of magnitude 6.3.
