People likely experienced very weak shaking there. Many smaller towns and villages are located closer to the epicenter and might have experienced stronger shaking. In the capital of Mexico, Mexico City, 363 km (225 mi) away from the epicenter, the earthquake could not be felt.The following table shows some of the places that might have been affected (or not) by the shaking.DistancePlaceMax. shaking intensity(*)RegionCountry54 km (33 mi)N of epicenterLas Ramaditas(pop: 152)III: WeakSan Marcos, Estado de GuerreroMexico56 km (35 mi)NE of epicenterPico del Monte(pop: 589)III: WeakFlorencio Villarreal, Estado de GuerreroMexico58 km (36 mi)N of epicenterTecomate Pesqueria(pop: 578)III: WeakSan Marcos, Estado de GuerreroMexico64 km (40 mi)N of epicenterLomas de Chapultepec(pop: 2,170)III: WeakAcapulco de Juarez, Estado de GuerreroMexico66 km (41 mi)NE of epicenterCopala(pop: 6,620)III: WeakEstado de GuerreroMexico67 km (42 mi)NE of epicenterCruz Grande(pop: 11,800)II: Very weakFlorencio Villarreal, Estado de GuerreroMexico67 km (42 mi)N of epicenterLas Vigas(pop: 4,500)II: Very weakSan Marcos, Estado de GuerreroMexico68 km (42 mi)N of epicenterEl Cortes(pop: 1,240)II: Very weakSan Marcos, Estado de GuerreroMexico69 km (43 mi)N of epicenterSan Marcos(pop: 13,300)II: Very weakEstado de GuerreroMexico69 km (43 mi)NW of epicenterCacahuate(pop: 72)II: Very weakAcapulco de Juarez, Estado de GuerreroMexico76 km (47 mi)N of epicenterEl Guineo(pop: 489)II: Very weakAyutla de los Libres, Estado de GuerreroMexico76 km (47 mi)NE of epicenterLa Bocanita(pop: 86)II: Very weakCuautepec, Estado de GuerreroMexico76 km (47 mi)NE of epicenterCuautepec(pop: 3,570)II: Very weakEstado de GuerreroMexico77 km (48 mi)NE of epicenterMarquelia(pop: 6,550)II: Very weakEstado de GuerreroMexico77 km (48 mi)N of epicenterAmatillo(pop: 3,300)II: Very weakAcapulco de Juarez, Estado de GuerreroMexico77 km (48 mi)N of epicenterRancho Viejo(pop: 1,120)II: Very weakSan Marcos, Estado de GuerreroMexico80 km (50 mi)N of epicenterRancho los Cantiles(pop: 18)II: Very weakSan Marcos, Estado de GuerreroMexico80 km (50 mi)NE of epicenterBarra de Tecoanapa(pop: 1,160)II: Very weakMarquelia, Estado de GuerreroMexico81 km (50 mi)N of epicenterBarrio Nuevo de los Muertos(pop: 1,170)II: Very weakAcapulco de Juarez, Estado de GuerreroMexico83 km (52 mi)NW of epicenterTres Palos(pop: 5,000)II: Very weakAcapulco de Juarez, Estado de GuerreroMexico84 km (52 mi)NE of epicenterTonala(pop: 2,180)II: Very weakAyutla de los Libres, Estado de GuerreroMexico87 km (54 mi)NE of epicenterPoza Verde(pop: 546)II: Very weakSan Luis Acatlan, Estado de GuerreroMexico89 km (55 mi)NE of epicenterAgua Zarca(pop: 1,150)II: Very weakJuchitan, Estado de GuerreroMexico92 km (57 mi)NE of epicenterZoyatlan(pop: 1,120)II: Very weakMarquelia, Estado de GuerreroMexico92 km (57 mi)NW of epicenterAcapulco de Juárez(pop: 658,600)II: Very weakEstado de GuerreroMexico100 km (62 mi)NE of epicenterSan Luis Acatlan(pop: 8,280)II: Very weakEstado de GuerreroMexico110 km (69 mi)NE of epicenterCamalotillo (El Camalotillo)(pop: 558)II: Very weakSan Luis Acatlan, Estado de GuerreroMexico363 km (225 mi)N of epicenterMexico City(pop: 12,294,200)I: Not feltCiudad de MexicoMexicoNotes:(*) Shaking intensity according to the Modified Mercalli Intensity Scale (MMI) and estimated using seismic models.User-reports for this quakeThere are no user reports for this quake yet.If you felt it, be the first to report it!Get the Android appCompare 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 1 km2 (0 square miles) as a first-order estimate. The length of the rupture zone thus was probably around 2 km (1 mi).[More info]Recorded aftershocks, latest first (0 quake)Sep 6, 2026 09:00 pm (GMT -7)44 minutes ago4.117 km0 km - This quakeOffshore Guerrero, 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 1,600 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: 0.17 quakes per year (or 1 quake every 5.8 years)Mag. 5 or higher: 1.39 quakes per yearMag. 4 or higher: 103 quakes per year (or 8.6 quakes per month)Mag. 3 or higher: 1,200 quakes per year (or 3.2 quakes per day)Mag. 2 or higher: 1,600 quakes per year (or 4.3 quakes per day)Mag. 1 or higher: 1,600 quakes per year (or 4.3 quakes per day)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 earthquake
