So far, we have received 3 reports for this quake from Mexico. The quake was reported to have been felt in up to approx. 20 km (12 mi) distance, with isolated cases to have felt the quake even 24 km (15 mi) away.Most reports came from Brisas de Zicatela (2 reports), a town with 9,800 inhabitants in Estado de Oaxaca in 25 km (15 mi) distance northeast of the epicenter, Mexico. 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!TranslateBrisas de Zicatela, Santa María Colotepec, Oaxaca (24.5 km ENE of epicenter) [Map] / Weak shaking (MMI III) / rattling, vibrating / 5-10 s : Laying in bed, everything started shaking and jt progressively got more intense before it stopped. 5 minutes later a shorter weekend shake followed.

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 shaking224–24 km (15–15.2 mi)24 km (15 mi)IV: Light shaking124–24 km (14.9–14.9 mi)24 km (15 mi)Notes(*) Reports are filtered to exclude those that are likely highly inaccurate or esaggerated.Only reports with latitude/longitude coordinate positions given (3 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 2 km2 (1 square miles) as a first-order estimate. The length of the rupture zone thus was probably around 2 km (2 mi).[More info]Recorded aftershocks, latest first (0 quake)Oct 20, 2026 08:41 am (Mexico City)24 minutes ago - felt4.310 km0 km - This quakeNorth Pacific Ocean, 24 km SW of Puerto Escondido, Estado de Oaxaca, MexicoMain Shock (this quake)MoreMap of aftershocksEarthquake statisticsAverage number of earthquakesBased on data from the past 56 years and our earthquake archive back to 1900, there are about 1,200 quakes on average per year in the area near the epicenter of this quake (within 100 km/61 mi):Mag. 7 or higher: 0.05 quakes per year (or 1 quake every 21.3 years)Mag. 6 or higher: 0.12 quakes per year (or 1 quake every 8.5 years)Mag. 5 or higher: 0.75 quakes per year (or 1 quake every 1.3 years)Mag. 4 or higher: 115 quakes per year (or 9.6 quakes per month)Mag. 3 or higher: 1,200 quakes per year (or 3.3 quakes per day)Mag. 2 or higher: 1,200 quakes per year (or 3.4 quakes per day)The area where this quake occurred has a very high level of seismic activity. It has had at least 6 quakes above magnitude 7 since 1900, which suggests that larger earthquakes of this size occur infrequently, probably on average approximately every 20 to 25 years.Number of quakes per yearPrevious quakes in the same area of this earthquake
