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, 380 km (236 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(*)RegionCountry10 km (6 mi)N of epicenterVatos(pop: 11)IV: LightLasithi, CreteGreece16 km (10 mi)NW of epicenterKolimbi(pop: 88)III: WeakHeraklion Regional Unit, CreteGreece18 km (11 mi)NE of epicenterIerapetra(pop: 12,400)III: WeakLasithi, CreteGreece19 km (12 mi)N of epicenterKalamafka(pop: 425)III: WeakLasithi, CreteGreece20 km (13 mi)N of epicenterSelakano(pop: 29)III: WeakLasithi, CreteGreece27 km (17 mi)NE of epicenterFerma(pop: 532)III: WeakLasithi, CreteGreece27 km (17 mi)NW of epicenterEmparos(pop: 247)III: WeakHeraklion Regional Unit, CreteGreece30 km (18 mi)NE of epicenterPacheia Ammos(pop: 574)III: WeakLasithi, CreteGreece33 km (20 mi)N of epicenterAgios Nikolaos(pop: 11,400)III: WeakLasithi, CreteGreece38 km (23 mi)E of epicenterMakry Gialos(pop: 760)III: WeakLasithi, CreteGreece38 km (24 mi)N of epicenterNeapoli(pop: 2,680)III: WeakLasithi, CreteGreece39 km (24 mi)NW of epicenterArkalochori(pop: 3,540)III: WeakHeraklion Regional Unit, CreteGreece41 km (26 mi)W of epicenterPyrgos(pop: 1,130)II: Very weakHeraklion Regional Unit, CreteGreece43 km (27 mi)N of epicenterMalia(pop: 4,340)II: Very weakHeraklion Regional Unit, CreteGreece47 km (29 mi)N of epicenterVrouchas(pop: 135)II: Very weakLasithi, CreteGreece52 km (33 mi)NW of epicenterAno Arhanes(pop: 3,910)II: Very weakHeraklion Regional Unit, CreteGreece53 km (33 mi)NW of epicenterKato Gouves(pop: 2,150)II: Very weakHeraklion Regional Unit, CreteGreece57 km (36 mi)NE of epicenterSitia(pop: 8,710)II: Very weakLasithi, CreteGreece59 km (37 mi)NW of epicenterAgia Varvara(pop: 2,170)II: Very weakHeraklion Regional Unit, CreteGreece61 km (38 mi)NW of epicenterNea Alikarnassos(pop: 12,900)II: Very weakHeraklion Regional Unit, CreteGreece61 km (38 mi)NW of epicenterIrakleion(pop: 137,200)II: Very weakHeraklion Regional Unit, CreteGreece65 km (41 mi)NW of epicenterKrouson(pop: 2,810)II: Very weakHeraklion Regional Unit, CreteGreece66 km (41 mi)NW of epicenterGazi(pop: 12,600)II: Very weakHeraklion Regional Unit, CreteGreece67 km (42 mi)W of epicenterMoires(pop: 6,380)II: Very weakHeraklion Regional Unit, CreteGreece68 km (42 mi)NE of epicenterPalekastro(pop: 1,090)II: Very weakLasithi, CreteGreece76 km (47 mi)NW of epicenterAgia Pelagia(pop: 480)II: Very weakHeraklion Regional Unit, CreteGreece77 km (48 mi)NW of epicenterAnogeia(pop: 2,550)II: Very weakRethymno, CreteGreece380 km (236 mi)NW of epicenterAthens(pop: 664,000): 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!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.

It has had at least 4 quakes above magnitude 6 since 2000, which suggests that larger earthquakes of this size occur infrequently, probably on average approximately every 5 to 10 years.Number of quakes per yearPrevious quakes in the same area of this earthquake
