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, 316 km (196 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(*)RegionCountry57 km (35 mi)NW of epicenterOnagawa Cho(pop: 6,430)II: Very weakOshika Gun, MiyagiJapan62 km (38 mi)NW of epicenterIshinomaki(pop: 138,500)II: Very weakMiyagiJapan67 km (42 mi)NW of epicenterYamoto(pop: 32,000)II: Very weakHigashimatsushima Shi, MiyagiJapan68 km (42 mi)NW of epicenterHigashimatsushima(pop: 39,100)II: Very weakMiyagiJapan73 km (45 mi)NW of epicenterShiogama(pop: 52,700)II: Very weakMiyagiJapan74 km (46 mi)NW of epicenterMatsushima(pop: 16,400)II: Very weakMiyagi Gun, MiyagiJapan76 km (47 mi)W of epicenterSoma(pop: 34,900)II: Very weakSoma Shi, FukushimaJapan78 km (48 mi)NW of epicenterRifu(pop: 36,000)II: Very weakMiyagi Gun, MiyagiJapan80 km (49 mi)W of epicenterWatari(pop: 33,500)II: Very weakMiyagiJapan80 km (50 mi)W of epicenterIwanuma(pop: 43,900)II: Very weakMiyagiJapan80 km (50 mi)SW of epicenterMinami-Soma(pop: 59,000)II: Very weakMinamisoma Shi, FukushimaJapan81 km (50 mi)N of epicenterMinamisanriku(pop: 12,200)II: Very weakMotoyoshi Gun, MiyagiJapan82 km (51 mi)NW of epicenterWakuya(pop: 15,800)II: Very weakToda Gun, MiyagiJapan84 km (52 mi)W of epicenterSendai(pop: 1,096,700)II: Very weakMiyagiJapan86 km (54 mi)W of epicenterKakuda(pop: 33,200)II: Very weakMiyagiJapan87 km (54 mi)NW of epicenterKogota(pop: 19,800)II: Very weakToda Gun, MiyagiJapan87 km (54 mi)W of epicenterMarumori(pop: 13,100)II: Very weakIgu-gun, MiyagiJapan88 km (55 mi)SW of epicenterNamie(pop: 21,900)II: Very weakFutaba-gun, FukushimaJapan88 km (55 mi)NW of epicenterTomiya(pop: 52,400)II: Very weakMiyagiJapan90 km (56 mi)W of epicenterOkawara(pop: 23,600)II: Very weakShibata-gun, MiyagiJapan92 km (57 mi)W of epicenterMurata(pop: 10,700)II: Very weakShibata-gun, MiyagiJapan95 km (59 mi)NW of epicenterFurukawa(pop: 76,300)II: Very weakOsaki Shi, MiyagiJapan95 km (59 mi)NW of epicenterTome(pop: 77,900)II: Very weakMiyagiJapan95 km (59 mi)NW of epicenterOsaki(pop: 128,800)II: Very weakOsaki Shi, MiyagiJapan100 km (62 mi)W of epicenterShiroishi(pop: 33,300)II: Very weakMiyagiJapan107 km (66 mi)NW of epicenterKurihara(pop: 66,600)II: Very weakMiyagiJapan112 km (70 mi)W of epicenterDate(pop: 59,600)II: Very weakFukushimaJapan116 km (72 mi)NW of epicenterIchinoseki(pop: 114,500)II: Very weakIwateJapan117 km (72 mi)W of epicenterFukushima(pop: 294,200)II: Very weakFukushimaJapan125 km (77 mi)W of epicenterYamagata(pop: 248,800)II: Very weakYamagataJapan125 km (78 mi)W of epicenterNihommatsu(pop: 53,600)II: Very weakNihonmatsu Shi, FukushimaJapan128 km (79 mi)W of epicenterTendo(pop: 65,400)II: Very weakTendo Shi, YamagataJapan130 km (81 mi)SW of epicenterIwaki(pop: 357,300)II: Very weakFukushimaJapan138 km (86 mi)NW of epicenterMizusawa(pop: 61,300)II: Very weakOshu Shi, IwateJapan138 km (86 mi)SW of epicenterKoriyama(pop: 327,700)II: Very weakKoriyama Shi, FukushimaJapan144 km (90 mi)W of epicenterYonezawa(pop: 94,500)II: Very weakYamagataJapan145 km (90 mi)SW of epicenterSukagawa(pop: 75,000)II: Very weakFukushimaJapan154 km (95 mi)N of epicenterKitakami(pop: 92,300)II: Very weakIwateJapan164 km (102 mi)N of epicenterHanamaki(pop: 94,700)II: Very weakIwateJapan316 km (196 mi)SW 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)Oct 10, 2025 09:24 pm (GMT +9)8 minutes ago4.055 km0 km - This quakeJapan: SE Off Miyagi PrefMain Shock (this quake)MoreMap of aftershocksEarthquake statisticsAverage number of earthquakesBased on data from the past 25 years and our earthquake archive back to 1900, there are about 7,800 quakes on average per year in the area near the epicenter of this quake (within 100 km/61 mi):Mag. 7 or higher: 0.13 quakes per year (or 1 quake every 7.7 years)Mag. 6 or higher: 1.91 quakes per yearMag. 5 or higher: 14.3 quakes per yearMag. 4 or higher: 100 quakes per year (or 8.3 quakes per month)Mag. 3 or higher: 452 quakes per year (or 37.6 quakes per month)Mag. 2 or higher: 1,600 quakes per year (or 4.4 quakes per day)Mag. 1 or higher: 6,300 quakes per year (or 17.2 quakes per day)The area where this quake occurred has a very high level of seismic activity. It has had at least 17 quakes above magnitude 7 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
