People likely experienced light shaking there. Several smaller towns and villages are located closer to the epicenter and might have experienced stronger shaking. In the capital of Greece, Athens, 255 km (159 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(*)RegionCountry27 km (17 mi)SE of epicenterKissamos(pop: 4,240)IV: LightChania, CreteGreece54 km (33 mi)E of epicenterChania(pop: 53,900)IV: LightCreteGreece55 km (34 mi)S of epicenterPalaiochora(pop: 2,370)IV: LightChania, CreteGreece80 km (50 mi)SE of epicenterGeorgioupolis(pop: 2,480)IV: LightChania, CreteGreece98 km (61 mi)E of epicenterRethymno(pop: 32,500)III: WeakCreteGreece156 km (97 mi)E of epicenterIrakleion(pop: 137,200)III: WeakHeraklion Regional Unit, CreteGreece180 km (112 mi)NW of epicenterSparti(pop: 16,200)III: WeakNomos Lakonias, PeloponneseGreece193 km (120 mi)NW of epicenterKalamata(pop: 54,100)III: WeakNomos Messinias, PeloponneseGreece224 km (139 mi)NW of epicenterTripoli(pop: 26,600)III: WeakNomos Arkadias, PeloponneseGreece240 km (149 mi)N of epicenterVoula(pop: 28,400)III: WeakNomarchia Anatolikis Attikis, AtticaGreece242 km (151 mi)N of epicenterGlyfada(pop: 87,300)III: WeakNomarchia Athinas, AtticaGreece247 km (153 mi)N of epicenterArgyroupoli(pop: 34,100)III: WeakNomarchia Athinas, AtticaGreece247 km (154 mi)N of epicenterAlimos(pop: 41,700)III: WeakNomarchia Athinas, AtticaGreece249 km (155 mi)N of epicenterPalaio Faliro(pop: 64,000)III: WeakNomarchia Athinas, AtticaGreece250 km (155 mi)N of epicenterAgios Dimitrios(pop: 71,300)III: WeakNomarchia Athinas, AtticaGreece250 km (155 mi)N of epicenterIlioupoli(pop: 78,200)III: WeakNomarchia Athinas, AtticaGreece250 km (155 mi)N of epicenterPiraeus(pop: 163,700)III: WeakNomos Attikis, AtticaGreece251 km (156 mi)N of epicenterNea Smyrni(pop: 73,100)III: WeakNomarchia Athinas, AtticaGreece251 km (156 mi)N of epicenterKallithea(pop: 100,600)III: WeakNomarchia Athinas, AtticaGreece252 km (157 mi)N of epicenterKeratsini(pop: 77,100)III: WeakNomos Piraios, AtticaGreece253 km (157 mi)N of epicenterNikaia(pop: 89,400)III: WeakNomos Piraios, AtticaGreece253 km (157 mi)N of epicenterVyronas(pop: 61,300)III: WeakNomarchia Athinas, AtticaGreece255 km (158 mi)N of epicenterZografos(pop: 71,000)III: WeakNomarchia Athinas, AtticaGreece255 km (158 mi)N of epicenterAigaleo(pop: 69,900)III: WeakNomarchia Athinas, AtticaGreece255 km (158 mi)N of epicenterKorydallos(pop: 63,400)III: WeakNomos Piraios, AtticaGreece255 km (159 mi)N of epicenterAthens(pop: 664,000)III: WeakNomarchia Athinas, AtticaGreece258 km (160 mi)N of epicenterChaidari(pop: 45,600)III: WeakNomarchia Athinas, AtticaGreece259 km (161 mi)N of epicenterPeristeri(pop: 140,000)III: WeakNomarchia Athinas, AtticaGreece259 km (161 mi)N of epicenterGalatsi(pop: 59,300)III: WeakNomarchia Athinas, AtticaGreece260 km (162 mi)N of epicenterAgia Paraskevi(pop: 59,700)III: WeakNomarchia Athinas, AtticaGreece260 km (162 mi)N of epicenterChalandri(pop: 74,200)III: WeakNomarchia Athinas, AtticaGreece261 km (162 mi)N of epicenterIlion(pop: 84,800)III: WeakNomarchia Athinas, AtticaGreece261 km (162 mi)N of epicenterNea Ionia(pop: 67,100)III: WeakNomarchia Athinas, AtticaGreece262 km (163 mi)N of epicenterPetroupolis(pop: 59,000)III: WeakNomarchia Athinas, AtticaGreece262 km (163 mi)N of epicenterPetroúpolis(pop: 59,000)III: WeakGreece263 km (164 mi)N of epicenterMarousi(pop: 72,300)III: WeakNomarchia Athinas, AtticaGreece263 km (164 mi)N of epicenterIrakleio(pop: 49,600)III: WeakNomarchia Athinas, AtticaGreece266 km (165 mi)N of epicenterKifissia(pop: 47,300)III: WeakNomarchia Athinas, AtticaGreece266 km (166 mi)N of epicenterAcharnes(pop: 99,300)III: WeakNomarchia Anatolikis Attikis, AtticaGreece323 km (201 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 (2)The first report about ground shaking reached us after only 1 minute, before other agencies reported it. So far, we have received 2 reports for this quake.

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 shaking236–58 km (23–36 mi)47 km (29 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.I 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! Other users would love to hear about it!If you did NOT feel the quake although you were in the area, please report it as well! Your contribution is valuable to earthquake science and seismic hazard analysis.Compare 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 20 km2 (8 square miles) as a first-order estimate. The length of the rupture zone thus was probably around 8 km (5 mi).[More info]Recorded aftershocks, latest first (0 quake)Jul 23, 2025 01:26 pm (Universal Time)3 minutes ago - felt5.347 km0 km - This quake54 km W of Chania, Chania, Crete, GreeceMain Shock (this quake)MoreMap of aftershocksEarthquake statisticsAverage number of earthquakesBased on data from the past 55 years and our earthquake archive back to 1900, there are about 602 quakes on average per year in the area near the epicenter of this quake (within 100 km/61 mi):Mag. 6 or higher: 0.09 quakes per year (or 1 quake every 11.4 years)Mag. 5 or higher: 0.49 quakes per year (or 1 quake every 2 years)Mag. 4 or higher: 8.6 quakes per yearMag. 3 or higher: 92 quakes per year (or 7.7 quakes per month)Mag. 2 or higher: 520 quakes per year (or 43 quakes per month)Mag. 1 or higher: 602 quakes per year (or 50 quakes per month)The area where this quake occurred has a very high level of seismic activity. It has had at least 11 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
