People likely experienced weak shaking there. Many smaller towns and villages are located closer to the epicenter and might have experienced stronger shaking. In the capital of Greece, Athens, 111 km (69 mi) away from the epicenter, the earthquake was probably felt as weak shaking.The following table shows some of the places that might have been affected (or not) by the shaking.DistancePlaceMax. shaking intensity(*)RegionCountry4 km (3 mi)NW of epicenterAstros(pop: 2,220)III: WeakNomos Arkadias, PeloponneseGreece23 km (14 mi)N of epicenterNafplio(pop: 14,600)III: WeakArgolida, PeloponneseGreece25 km (15 mi)SE of epicenterLeonidio(pop: 3,020)III: WeakNomos Arkadias, PeloponneseGreece29 km (18 mi)N of epicenterArgos(pop: 22,200)III: WeakArgolida, PeloponneseGreece35 km (22 mi)NW of epicenterTripoli(pop: 26,600)III: WeakNomos Arkadias, PeloponneseGreece37 km (23 mi)E of epicenterKranidi(pop: 4,010)III: WeakArgolida, PeloponneseGreece38 km (23 mi)NE of epicenterLigourion(pop: 2,480)III: WeakArgolida, PeloponneseGreece39 km (24 mi)E of epicenterSpetses(pop: 4,000)III: WeakNomos Piraios, AtticaGreece41 km (26 mi)SW of epicenterPellana(pop: 1,930)III: WeakNomos Lakonias, PeloponneseGreece43 km (27 mi)SW of epicenterSparti(pop: 16,200)III: WeakNomos Lakonias, PeloponneseGreece47 km (29 mi)NE of epicenterPalaia Epidavros(pop: 1,620)III: WeakArgolida, PeloponneseGreece50 km (31 mi)N of epicenterKhiliomodhi(pop: 1,700)III: WeakNomos Korinthias, PeloponneseGreece51 km (31 mi)N of epicenterNemea(pop: 3,850)III: WeakNomos Korinthias, PeloponneseGreece53 km (33 mi)W of epicenterMegalopoli(pop: 5,280)III: WeakNomos Arkadias, PeloponneseGreece66 km (41 mi)N of epicenterCorinth(pop: 30,200)III: WeakPeloponneseGreece67 km (41 mi)SW of epicenterKalamata(pop: 54,100)III: WeakNomos Messinias, PeloponneseGreece71 km (44 mi)N of epicenterLoutraki(pop: 11,600)III: WeakNomos Korinthias, PeloponneseGreece72 km (44 mi)N of epicenterKiato(pop: 9,810)III: WeakNomos Korinthias, PeloponneseGreece87 km (54 mi)NE of epicenterMegara(pop: 23,500)III: WeakNomos Attikis, AtticaGreece94 km (58 mi)NE of epicenterSalamina(pop: 25,400)III: WeakNomos Piraios, AtticaGreece99 km (61 mi)NE of epicenterPerama(pop: 25,400)III: WeakNomos Piraios, AtticaGreece102 km (63 mi)NE of epicenterKeratsini(pop: 77,100)III: WeakNomos Piraios, AtticaGreece102 km (63 mi)NE of epicenterPiraeus(pop: 163,700)III: WeakNomos Attikis, AtticaGreece104 km (65 mi)NE of epicenterNikaia(pop: 89,400)III: WeakNomos Piraios, AtticaGreece105 km (65 mi)NE of epicenterPalaio Faliro(pop: 64,000)III: WeakNomarchia Athinas, AtticaGreece105 km (65 mi)NE of epicenterGlyfada(pop: 87,300)III: WeakNomarchia Athinas, AtticaGreece105 km (65 mi)NE of epicenterKorydallos(pop: 63,400)III: WeakNomos Piraios, AtticaGreece106 km (66 mi)NE of epicenterKallithea(pop: 100,600)III: WeakNomarchia Athinas, AtticaGreece107 km (66 mi)NE of epicenterNea Smyrni(pop: 73,100)III: WeakNomarchia Athinas, AtticaGreece107 km (67 mi)NE of epicenterAigaleo(pop: 69,900)III: WeakNomarchia Athinas, AtticaGreece108 km (67 mi)NE of epicenterAgios Dimitrios(pop: 71,300)III: WeakNomarchia Athinas, AtticaGreece110 km (68 mi)NE of epicenterIlioupoli(pop: 78,200)III: WeakNomarchia Athinas, AtticaGreece110 km (69 mi)NE of epicenterPeristeri(pop: 140,000)III: WeakNomarchia Athinas, AtticaGreece111 km (69 mi)NE of epicenterAthens(pop: 664,000)III: WeakNomarchia Athinas, AtticaGreece112 km (69 mi)NE of epicenterPetroúpolis(pop: 59,000)II: Very weakGreece112 km (70 mi)NE of epicenterIlion(pop: 84,800)II: Very weakNomarchia Athinas, AtticaGreece113 km (70 mi)NE of epicenterZografos(pop: 71,000)II: Very weakNomarchia Athinas, AtticaGreece118 km (73 mi)NE of epicenterAcharnes(pop: 99,300)II: Very weakNomarchia Anatolikis Attikis, AtticaGreece118 km (74 mi)NE of epicenterChalandri(pop: 74,200)II: Very weakNomarchia Athinas, AtticaGreece132 km (82 mi)NW of epicenterPátrai(pop: 168,000)II: Very weakAchaea, West GreeceGreeceNotes:(*) Shaking intensity according to the Modified Mercalli Intensity Scale (MMI) and estimated using seismic models.User-reports for this quake (7)So far, we have received 7 reports for this quake from Greece and France.

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 shaking25.6–105 km (3.5–65 mi)55 km (34 mi)III: Weak shaking365–113 km (40–70 mi)83 km (51 mi)V: Moderate shaking123–23 km (14.4–14.4 mi)23 km (14 mi)Notes(*) Reports are filtered to exclude those that are likely highly inaccurate or esaggerated.Only reports with latitude/longitude coordinate positions given (7 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 4 km2 (2 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)Aug 29, 2026 02:55 am (Athens)15 minutes ago - felt4.667 km0 km - This quake35 km SE of Tripoli, Nomos Arkadias, Peloponnese, GreeceMain 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 2,500 quakes on average per year in the area near the epicenter of this quake (within 100 km/61 mi):Mag. 6 or higher: 0.1 quakes per year (or 1 quake every 10.5 years)Mag. 5 or higher: 0.38 quakes per year (or 1 quake every 2.7 years)Mag. 4 or higher: 6.4 quakes per yearMag. 3 or higher: 70 quakes per year (or 5.9 quakes per month)Mag. 2 or higher: 704 quakes per year (or 59 quakes per month)Mag. 1 or higher: 2,400 quakes per year (or 6.7 quakes per day)The area where this quake occurred has a very high level of seismic activity. It has had at least 12 quakes above magnitude 6 since 1900, which suggests that larger earthquakes of this size occur infrequently, probably on average approximately every 10 to 15 years.Number of quakes per yearPrevious quakes in the same area of this earthquake
