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, 258 km (160 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(*)RegionCountry44 km (27 mi)W of epicenterNamie(pop: 21,900)II: Very weakFutaba-gun, FukushimaJapan47 km (29 mi)SW of epicenterTomioka(pop: 2,130)II: Very weakFutaba-gun, FukushimaJapan48 km (30 mi)W of epicenterMinami-Soma(pop: 59,000)II: Very weakMinamisoma Shi, FukushimaJapan57 km (35 mi)SW of epicenterOyauchi(pop: 5,410)II: Very weakFutaba-gun, FukushimaJapan60 km (37 mi)NW of epicenterSoma(pop: 34,900)II: Very weakSoma Shi, FukushimaJapan62 km (38 mi)W of epicenterShimokawauchi(pop: 2,040)II: Very weakFutaba-gun, FukushimaJapan70 km (43 mi)W of epicenterKusano(pop: 1,320)II: Very weakSoma-gun, FukushimaJapan70 km (44 mi)NW of epicenterSakamoto(pop: 12,000)II: Very weakWatari-gun, MiyagiJapan74 km (46 mi)SW of epicenterIwaki(pop: 357,300)II: Very weakFukushimaJapan75 km (47 mi)W of epicenterYamakiya(pop: 12,200)II: Very weakDate-gun, FukushimaJapan79 km (49 mi)NW of epicenterMarumori(pop: 13,100)II: Very weakIgu-gun, MiyagiJapan80 km (49 mi)W of epicenterTamura(pop: 35,200)II: Very weakFukushimaJapan80 km (50 mi)W of epicenterOno-niimachi(pop: 9,470)II: Very weakTamura-gun, FukushimaJapan82 km (51 mi)W of epicenterFunehikimachi-funehiki(pop: 23,500)II: Very weakTamura-shi, FukushimaJapan82 km (51 mi)NW of epicenterWatari(pop: 33,500)II: Very weakMiyagiJapan83 km (52 mi)NW of epicenterKakuda(pop: 33,200)II: Very weakMiyagiJapan88 km (55 mi)NW of epicenterIwanuma(pop: 44,100)II: Very weakMiyagiJapan88 km (55 mi)NW of epicenterYanagawamachi-saiwaicho(pop: 20,800)II: Very weakDate-shi, FukushimaJapan90 km (56 mi)W of epicenterMiharu(pop: 17,500)II: Very weakTamura-gun, FukushimaJapan91 km (56 mi)NW of epicenterHobaramachi(pop: 24,500)II: Very weakDate-shi, FukushimaJapan91 km (57 mi)NW of epicenterOkawara(pop: 23,600)II: Very weakShibata-gun, MiyagiJapan92 km (57 mi)NW of epicenterNatori-shi(pop: 78,700)II: Very weakNatori Shi, MiyagiJapan94 km (58 mi)NW of epicenterKoori(pop: 11,700)II: Very weakDate-shi, FukushimaJapan95 km (59 mi)W of epicenterNihommatsu(pop: 53,600)II: Very weakNihonmatsu Shi, FukushimaJapan95 km (59 mi)W of epicenterDate(pop: 59,600)II: Very weakFukushimaJapan95 km (59 mi)W of epicenterFukushima(pop: 294,200)II: Very weakFukushimaJapan95 km (59 mi)W of epicenterFukushima(pop: 294,200)II: Very weakFukushimaJapan95 km (59 mi)NW of epicenterShobudahama(pop: 18,100)II: Very weakMiyagi Gun, MiyagiJapan96 km (59 mi)NW of epicenterShiroishi(pop: 33,300)II: Very weakMiyagiJapan97 km (60 mi)NW of epicenterMurata(pop: 38,300)II: Very weakShibata-gun, MiyagiJapan97 km (60 mi)W of epicenterMotomiya(pop: 30,200)II: Very weakFukushimaJapan99 km (62 mi)NW of epicenterTagajo-shi(pop: 62,800)II: Very weakTagajo Shi, MiyagiJapan99 km (62 mi)W of epicenterKoriyama(pop: 327,700)II: Very weakKoriyama Shi, FukushimaJapan100 km (62 mi)NW of epicenterShiogama(pop: 52,700)II: Very weakMiyagiJapan102 km (63 mi)W of epicenterSukagawa(pop: 75,000)II: Very weakFukushimaJapan102 km (63 mi)NW of epicenterSendai(pop: 1,096,700)II: Very weakMiyagiJapan103 km (64 mi)N of epicenterIshinomaki(pop: 140,200)II: Very weakMiyagiJapan117 km (73 mi)W of epicenterShirakawa(pop: 59,500)II: Very weakFukushimaJapan137 km (85 mi)W of epicenterAizu-Wakamatsu(pop: 118,200)II: Very weakFukushimaJapan258 km (160 mi)SW of epicenterTokyo(pop: 9,733,300)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!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)Apr 6, 2026 02:28 am (GMT +9)7 minutes ago4.160 km0 km - This quakeNear East Coast OF Honshu, JapanMain Shock (this quake)MoreMap of aftershocksEarthquake statisticsAverage number of earthquakesBased on data from the past 26 years and our earthquake archive back to 1900, there are about 8,000 quakes on average per year in the area near the epicenter of this quake (within 100 km/61 mi):Mag. 7 or higher: 0.1 quakes per year (or 1 quake every 10.5 years)Mag. 6 or higher: 1.28 quakes per yearMag. 5 or higher: 14.4 quakes per yearMag. 4 or higher: 96 quakes per year (or 8 quakes per month)Mag. 3 or higher: 430 quakes per year (or 35.8 quakes per month)Mag. 2 or higher: 1,600 quakes per year (or 4.3 quakes per day)Mag. 1 or higher: 6,500 quakes per year (or 17.8 quakes per day)The area where this quake occurred has a very high level of seismic activity. It has had at least 12 quakes above magnitude 7 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
