So far, we have received 2 reports for this quake from Chile. The quake was reported to have been felt in up to approx. 40 km (25 mi) distance, with isolated cases to have felt the quake even 40 km (25 mi) away.Most reports came from Calama, a city with more than 170,000 inhabitants in Region de Antofagasta in 39 km (25 mi) distance southwest 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.Contribute:Leave a comment if you find a particular report interesting or want to add to it.Flag as inappropriate.Mark as helpful or interesting.Send your own user report!TranslateCalama (38.3 km SW of epicenter) [Map] / Very weak shaking (MMI II) / 20-30 sCalama (40.3 km SW of epicenter) [Map] / Very weak shaking (MMI II) / 5-10 s : Algo suave pero capaz de despertar List of cities/places with most reportsPlaceDistance from epicenterAverage reported Shaking IntensityNr. of reportsCalama, Region de Antofagasta, Chile(Pop.: 166,334)39 km (25 mi)SW of epicenterII: Very weak shaking2Note: 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 (*)II: Very weak shaking238–40 km (24–25 mi)39 km (24 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.Get the Android appI 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!

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)Oct 8, 2026 02:35 am (Santiago)31 minutes ago - felt4.5121 km0 km - This quake39 km NE of Calama, Provincia de El Loa, Region de Antofagasta, ChileMain Shock (this quake)MoreMap of aftershocksEarthquake statisticsAverage number of earthquakesBased on data from the past 26 years and our earthquake archive back to 1900, there are about 1,100 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: 0.16 quakes per year (or 1 quake every 6.2 years)Mag. 5 or higher: 3.9 quakes per yearMag. 4 or higher: 75 quakes per year (or 6.2 quakes per month)Mag. 3 or higher: 495 quakes per year (or 41 quakes per month)Mag. 2 or higher: 1,100 quakes per year (or 3.1 quakes per day)Mag. 1 or higher: 1,100 quakes per year (or 3.1 quakes per day)The area where this quake occurred has a very high level of seismic activity.
