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 Japan, Tokyo, 438 km (272 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)NW of epicenterKainan(pop: 43,400)IV: LightWakayamaJapan17 km (10 mi)N of epicenterIwade(pop: 53,300)IV: LightWakayamaJapan17 km (10 mi)W of epicenterArida(pop: 26,800)IV: LightWakayamaJapan19 km (12 mi)NW of epicenterMinato(pop: 375,300)IV: LightWakayama Shi, WakayamaJapan19 km (12 mi)NW of epicenterWakayama(pop: 351,000)III: WeakWakayamaJapan21 km (13 mi)NE of epicenterKinokawa(pop: 60,600)III: WeakWakayamaJapan26 km (16 mi)N of epicenterHannan(pop: 52,400)III: WeakOsakaJapan27 km (17 mi)SW of epicenterGobo(pop: 22,400)III: WeakGobo Shi, WakayamaJapan35 km (22 mi)N of epicenterIzumisano(pop: 98,800)III: WeakOsakaJapan38 km (24 mi)NE of epicenterHashimoto(pop: 61,100)III: WeakWakayamaJapan39 km (24 mi)N of epicenterKaizuka(pop: 92,600)III: WeakOsakaJapan41 km (26 mi)N of epicenterKishiwada(pop: 205,600)III: WeakOsakaJapan41 km (26 mi)S of epicenterTanabe(pop: 71,000)III: WeakWakayamaJapan44 km (28 mi)N of epicenterIzumi(pop: 184,600)III: WeakOsakaJapan45 km (28 mi)N of epicenterIzumiotsu(pop: 73,800)III: WeakIzumiotsu Shi, OsakaJapan46 km (29 mi)NE of epicenterKawachi-Nagano(pop: 96,300)III: WeakOsakaJapan46 km (29 mi)NE of epicenterGojo(pop: 34,300)III: WeakGojo-shi, NaraJapan46 km (29 mi)NW of epicenterSumoto(pop: 42,100)III: WeakHyōgoJapan47 km (29 mi)S of epicenterShirahama(pop: 23,300)III: WeakNishimuro-gun, WakayamaJapan48 km (30 mi)N of epicenterTakaishi(pop: 60,500)III: WeakOsakaJapan52 km (32 mi)W of epicenterMinamiawaji(pop: 45,500)III: WeakHyōgoJapan53 km (33 mi)NE of epicenterTondabayashicho(pop: 132,900)III: WeakTondabayashi Shi, OsakaJapan56 km (35 mi)N of epicenterSakai(pop: 782,300)III: WeakOsakaJapan57 km (35 mi)NE of epicenterMatsubara(pop: 130,900)III: WeakOsakaJapan57 km (35 mi)NE of epicenterHabikino(pop: 109,500)III: WeakOsakaJapan61 km (38 mi)NE of epicenterKashihara(pop: 79,100)III: WeakKashiwara-shi, OsakaJapan63 km (39 mi)W of epicenterAnan(pop: 70,300)III: WeakTokushimaJapan64 km (40 mi)NE of epicenterYao(pop: 273,200)III: WeakOsakaJapan64 km (40 mi)NE of epicenterKashihara-shi(pop: 124,500)III: WeakKashihara-shi, NaraJapan67 km (42 mi)NW of epicenterAkashi(pop: 303,600)II: Very weakHyōgoJapan68 km (42 mi)N of epicenterHigashi-osaka(pop: 489,100)II: Very weakHigashiosaka Shi, OsakaJapan69 km (43 mi)N of epicenterNishinomiya(pop: 485,600)II: Very weakHyōgoJapan69 km (43 mi)N of epicenterOsaka(pop: 2,753,900)II: Very weakOsakaJapan69 km (43 mi)N of epicenterAmagasaki(pop: 459,600)II: Very weakHyōgoJapan70 km (43 mi)N of epicenterAshiya(pop: 93,900)II: Very weakHyōgoJapan74 km (46 mi)NE of epicenterDaito(pop: 119,300)II: Very weakDaito Shi, OsakaJapan75 km (46 mi)NE of epicenterIkoma(pop: 120,700)II: Very weakNaraJapan75 km (46 mi)N of epicenterMoriguchi(pop: 142,700)II: Very weakOsakaJapan75 km (47 mi)N of epicenterKadoma(pop: 131,700)II: Very weakOsakaJapan438 km (272 mi)NE of epicenterTokyo(pop: 8,336,600)I: Not feltTokyoJapanNotes:(*) 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.

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)Nov 2, 2025 07:30 am (GMT +9)5 minutes ago4.110 km0 km - This quakeJapan: Near S. Coast of Western HonshuMain 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 3,000 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 9.7 years)Mag. 5 or higher: 0.62 quakes per year (or 1 quake every 1.6 years)Mag. 4 or higher: 8.7 quakes per yearMag. 3 or higher: 37.4 quakes per year (or 3.1 quakes per month)Mag. 2 or higher: 138 quakes per year (or 11.5 quakes per month)Mag. 1 or higher: 710 quakes per year (or 59 quakes per month)The area where this quake occurred has a very high level of seismic activity. It has had at least 13 quakes above magnitude 6 since 1900, 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
