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 Greece, Athens, 210 km (131 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(*)RegionCountry5 km (3 mi)NE of epicenterOchia(pop: 56)IV: LightNomos Lakonias, PeloponneseGreece12 km (7 mi)E of epicenterPorto Kagio(pop: 19)IV: LightNomos Lakonias, PeloponneseGreece23 km (14 mi)NE of epicenterKotronas(pop: 292)III: WeakNomos Lakonias, PeloponneseGreece25 km (15 mi)N of epicenterAreopoli(pop: 888)III: WeakNomos Lakonias, PeloponneseGreece39 km (24 mi)NE of epicenterGytheion(pop: 4,280)III: WeakNomos Lakonias, PeloponneseGreece45 km (28 mi)N of epicenterKastania(pop: 55)III: WeakNomos Lakonias, PeloponneseGreece45 km (28 mi)N of epicenterStoupa(pop: 600)III: WeakNomos Messinias, PeloponneseGreece52 km (32 mi)N of epicenterKrokees(pop: 1,330)III: WeakNomos Lakonias, PeloponneseGreece53 km (33 mi)NW of epicenterKoroni(pop: 1,620)III: WeakNomos Messinias, PeloponneseGreece53 km (33 mi)NE of epicenterSkala(pop: 2,820)III: WeakNomos Lakonias, PeloponneseGreece55 km (34 mi)NE of epicenterAsopos(pop: 4,160)III: WeakNomos Lakonias, PeloponneseGreece56 km (35 mi)E of epicenterElafonisos(pop: 745)III: WeakNomos Lakonias, PeloponneseGreece56 km (35 mi)E of epicenterPotamos(pop: 476)III: WeakNomos Piraios, AtticaGreece57 km (35 mi)N of epicenterKampos(pop: 372)III: WeakNomos Messinias, PeloponneseGreece57 km (35 mi)NE of epicenterKato Glykovrysi(pop: 1,750)III: WeakNomos Lakonias, PeloponneseGreece58 km (36 mi)N of epicenterXirokambion(pop: 995)III: WeakNomos Lakonias, PeloponneseGreece64 km (40 mi)NE of epicenterMetamorfosi(pop: 504)II: Very weakNomos Lakonias, PeloponneseGreece65 km (40 mi)E of epicenterAgios Fokas(pop: 19)II: Very weakNomos Lakonias, PeloponneseGreece65 km (40 mi)N of epicenterRizana(pop: 27)II: Very weakNomos Messinias, PeloponneseGreece65 km (41 mi)SE of epicenterKythira(pop: 281)II: Very weakNomos Piraios, AtticaGreece66 km (41 mi)NE of epicenterGefyra(pop: 1,300)II: Very weakNomos Lakonias, PeloponneseGreece69 km (43 mi)NE of epicenterGeraki(pop: 1,320)II: Very weakNomos Lakonias, PeloponneseGreece69 km (43 mi)NW of epicenterPetalidi(pop: 2,560)II: Very weakNomos Messinias, PeloponneseGreece69 km (43 mi)E of epicenterAvlemonas(pop: 81)II: Very weakNomos Piraios, AtticaGreece70 km (43 mi)N of epicenterKalamata(pop: 54,100)II: Very weakNomos Messinias, PeloponneseGreece71 km (44 mi)N of epicenterSparti(pop: 16,200)II: Very weakNomos Lakonias, PeloponneseGreece72 km (45 mi)NW of epicenterMethoni(pop: 1,170)II: Very weakNomos Messinias, PeloponneseGreece74 km (46 mi)NE of epicenterGérakas(pop: 120)II: Very weakNomos Lakonias, PeloponneseGreece77 km (48 mi)NW of epicenterSoulinari(pop: 322)II: Very weakNomos Messinias, PeloponneseGreece79 km (49 mi)NW of epicenterPylos(pop: 2,350)II: Very weakNomos Messinias, PeloponneseGreece80 km (49 mi)NW of epicenterAris(pop: 1,040)II: Very weakNomos Messinias, PeloponneseGreece85 km (53 mi)NW of epicenterAristomenis(pop: 1,700)II: Very weakNomos Messinias, PeloponneseGreece88 km (55 mi)NE of epicenterPoulithra(pop: 598)II: Very weakNomos Arkadias, PeloponneseGreece94 km (59 mi)NW of epicenterGargalianoi(pop: 6,280)II: Very weakNomos Messinias, PeloponneseGreece105 km (65 mi)NW of epicenterFiliatra(pop: 6,970)II: Very weakNomos Messinias, PeloponneseGreece210 km (131 mi)NE of epicenterAthens(pop: 664,000)I: Not feltNomarchia Athinas, AtticaGreeceNotes:(*) 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)May 25, 2026 01:29 am (Universal Time)2 minutes ago4.010 km0 km - This quakeGreece: 62.8 km WNW of KithiraMain 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 810 quakes on average per year in the area near the epicenter of this quake (within 100 km/61 mi):Mag. 7 or higher: 0.02 quakes per year (or 1 quake every 41.7 years)Mag. 6 or higher: 0.1 quakes per year (or 1 quake every 9.7 years)Mag. 5 or higher: 0.79 quakes per year (or 1 quake every 1.3 years)Mag. 4 or higher: 8.4 quakes per yearMag. 3 or higher: 75 quakes per year (or 6.3 quakes per month)Mag. 2 or higher: 499 quakes per year (or 42 quakes per month)Mag. 1 or higher: 804 quakes per year (or 67 quakes per month)The area where this quake occurred has a very high level of seismic activity. It has had at least 3 quakes above magnitude 7 since 1900, which suggests that larger earthquakes of this size occur infrequently, probably on average approximately every 40 to 45 years.Number of quakes per yearPrevious quakes in the same area of this earthquake
