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 Taiwan, Taipei, 342 km (213 mi) away from the epicenter, the earthquake was probably felt as very weak shaking.The following table shows some of the places that might have been affected (or not) by the shaking.DistancePlaceMax. shaking intensity(*)RegionCountry58 km (36 mi)SE of epicenterHirara(pop: 34,400)IV: LightMiyakojima Shi, OkinawaJapan59 km (37 mi)SE of epicenterMiyakojima(pop: 54,900)IV: LightOkinawaJapan62 km (38 mi)S of epicenterTarama(pop: 1,190)IV: LightMiyako-gun, OkinawaJapan122 km (76 mi)SW of epicenterIshigaki(pop: 47,600)III: WeakOkinawaJapan150 km (93 mi)SW of epicenterShirahama(pop: 3,940)III: WeakYaeyama-gun, OkinawaJapan228 km (142 mi)NE of epicenterKumejima(pop: 7,190)III: WeakShimajiri-gun, OkinawaJapan295 km (183 mi)E of epicenterItoman(pop: 61,000)II: Very weakOkinawaJapan298 km (185 mi)NE of epicenterTomigusuku(pop: 64,600)II: Very weakOkinawaJapan299 km (186 mi)NE of epicenterNaha(pop: 317,600)II: Very weakOkinawaJapan302 km (187 mi)E of epicenterYaese(pop: 30,900)II: Very weakShimajiri-gun, OkinawaJapan303 km (188 mi)NE of epicenterKanegusuku(pop: 40,400)II: Very weakShimajiri-gun, OkinawaJapan304 km (189 mi)E of epicenterNanjo(pop: 44,000)II: Very weakNanjo Shi, OkinawaJapan306 km (190 mi)NE of epicenterYonabaru(pop: 19,700)II: Very weakShimajiri-gun, OkinawaJapan306 km (190 mi)NE of epicenterUrasoe(pop: 115,700)II: Very weakOkinawaJapan307 km (191 mi)NE of epicenterNishihara(pop: 35,000)II: Very weakUrasoe Shi, OkinawaJapan309 km (192 mi)NE of epicenterGinowan(pop: 100,100)II: Very weakOkinawaJapan310 km (193 mi)NE of epicenterNakagusuku(pop: 22,200)II: Very weakNakagami, OkinawaJapan311 km (194 mi)NE of epicenterChatan(pop: 28,200)II: Very weakNakagami, OkinawaJapan313 km (195 mi)NE of epicenterYomitan(pop: 41,200)II: Very weakNakagami, OkinawaJapan313 km (195 mi)NE of epicenterKishaba(pop: 18,000)II: Very weakNakagami, OkinawaJapan315 km (196 mi)NE of epicenterOkinawa(pop: 142,800)II: Very weakOkinawaJapan320 km (199 mi)W of epicenterKeelung(pop: 362,500)II: Very weakTaiwanTaiwan321 km (200 mi)NE of epicenterIshikawa(pop: 22,400)II: Very weakUruma Shi, OkinawaJapan322 km (200 mi)NE of epicenterKatsuren-haebaru(pop: 34,200)II: Very weakUruma Shi, OkinawaJapan323 km (200 mi)NE of epicenterGushikawa(pop: 65,300)II: Very weakUruma Shi, OkinawaJapan323 km (200 mi)NE of epicenterUruma(pop: 125,300)II: Very weakOkinawaJapan323 km (201 mi)W of epicenterYilan(pop: 94,200)II: Very weakTaiwanTaiwan329 km (204 mi)W of epicenterXizhi(pop: 204,600)II: Very weakNew Taipei City, TaipeiTaiwan336 km (209 mi)W of epicenterNeihu(pop: 274,500)II: Very weakTaipei City, TaiwanTaiwan342 km (213 mi)W of epicenterTaipei(pop: 7,871,900)II: Very weakTaiwanTaiwan345 km (214 mi)NE of epicenterNago(pop: 63,600)II: Very weakOkinawaJapan348 km (216 mi)W of epicenterBanqiao(pop: 551,200)II: Very weakNew Taipei City, TaipeiTaiwan349 km (217 mi)W of epicenterNew Taipei City(pop: 4,004,400)II: Very weakNew Taipei City, TaipeiTaiwan350 km (217 mi)W of epicenterDanshui(pop: 189,300)II: Very weakNew Taipei City, TaipeiTaiwan353 km (219 mi)W of epicenterShulin(pop: 180,000)II: Very weakNew Taipei City, TaipeiTaiwan359 km (223 mi)W of epicenterSanxia(pop: 115,200)II: Very weakNew Taipei City, TaipeiTaiwan361 km (225 mi)W of epicenterHualien City(pop: 99,500)II: Very weakHualien, TaiwanTaiwan363 km (226 mi)W of epicenterTaoyuan(pop: 475,800)II: Very weakTaiwanTaiwan366 km (227 mi)W of epicenterTaoyuan City(pop: 402,000)II: Very weakTaoyuan, TaiwanTaiwan367 km (228 mi)W of epicenterBade(pop: 209,100)II: Very weakTaoyuan, TaiwanTaiwanNotes:(*) 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 13 km2 (5 square miles) as a first-order estimate. The length of the rupture zone thus was probably around 6 km (4 mi).[More info]Recorded aftershocks, latest first (0 quake)Feb 28, 2026 12:57 pm (Universal Time)7 minutes ago5.110 km0 km - This quakeNortheast of TaiwanMain 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 321 quakes on average per year in the area near the epicenter of this quake (within 100 km/61 mi):Mag. 7 or higher: 0.02 quakes per year (or 1 quake every 41.7 years)Mag. 6 or higher: 0.12 quakes per year (or 1 quake every 8.4 years)Mag. 5 or higher: 1.42 quakes per yearMag. 4 or higher: 16.5 quakes per yearMag. 3 or higher: 34.6 quakes per year (or 2.9 quakes per month)Mag. 2 or higher: 130 quakes per year (or 10.8 quakes per month)Mag. 1 or higher: 296 quakes per year (or 24.6 quakes per month)The area where this quake occurred has a very high level of seismic activity. It has had at least 3 quakes above magnitude 7 since 1900, which suggests that larger earthquakes of this size occur infrequently, probably on average approximately every 40 to 45 years.Number of quakes per yearPrevious quakes in the same area of this earthquake
