People likely experienced weak 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, 240 km (149 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(*)RegionCountry43 km (27 mi)N of epicenterShirahama(pop: 300)III: WeakYaeyama-gun, OkinawaJapan68 km (42 mi)NE of epicenterIshigaki(pop: 44,800)III: WeakOkinawaJapan80 km (50 mi)NW of epicenterYonakuni(pop: 1,680)III: WeakYaeyama-gun, OkinawaJapan194 km (121 mi)NE of epicenterHirara(pop: 34,400)II: Very weakMiyakojima Shi, OkinawaJapan194 km (121 mi)NE of epicenterMiyakojima(pop: 54,900)II: Very weakOkinawaJapan203 km (126 mi)W of epicenterHualien City(pop: 350,500)II: Very weakHualien, TaiwanTaiwan205 km (127 mi)NW of epicenterYilan(pop: 94,200)II: Very weakTaiwanTaiwan226 km (141 mi)NW of epicenterKeelung(pop: 397,500)II: Very weakTaiwanTaiwan229 km (142 mi)NW of epicenterXizhi(pop: 204,600)II: Very weakNew Taipei City, TaipeiTaiwan236 km (147 mi)NW of epicenterNeihu(pop: 271,600)II: Very weakTaipei City, TaiwanTaiwan240 km (149 mi)NW of epicenterTaipei(pop: 7,871,900)II: Very weakTaiwanTaiwan244 km (151 mi)NW of epicenterBanqiao(pop: 543,300)II: Very weakNew Taipei City, TaipeiTaiwan246 km (153 mi)NW of epicenterShulin(pop: 180,000)II: Very weakNew Taipei City, TaipeiTaiwan247 km (153 mi)NW of epicenterNew Taipei City(pop: 4,004,400)II: Very weakNew Taipei City, TaipeiTaiwan248 km (154 mi)NW of epicenterSanxia(pop: 115,200)II: Very weakNew Taipei City, TaipeiTaiwan251 km (156 mi)NW of epicenterYingge(pop: 87,900)II: Very weakNew Taipei City, TaipeiTaiwan254 km (158 mi)NW of epicenterDaxi(pop: 94,200)II: Very weakTaoyuan, TaiwanTaiwan254 km (158 mi)NW of epicenterSanzhi(pop: 23,500)II: Very weakNew Taipei City, TaipeiTaiwan254 km (158 mi)NW of epicenterDanshui(pop: 189,300)II: Very weakNew Taipei City, TaipeiTaiwan256 km (159 mi)NW of epicenterBade(pop: 209,100)II: Very weakTaoyuan, TaiwanTaiwan258 km (160 mi)NW of epicenterTaoyuan City(pop: 402,000)II: Very weakTaoyuan, TaiwanTaiwan267 km (166 mi)W of epicenterPuli(pop: 86,400)II: Very weakNantou, TaiwanTaiwan281 km (175 mi)W of epicenterHsinchu(pop: 404,100)II: Very weakTaiwanTaiwan283 km (176 mi)W of epicenterToufen Township(pop: 106,300)II: Very weakMiaoli, TaiwanTaiwan286 km (178 mi)SW of epicenterTaitung(pop: 103,300)II: Very weakTaiwanTaiwan291 km (181 mi)W of epicenterLugu(pop: 17,700)I: Not feltNantou, TaiwanTaiwan295 km (183 mi)W of epicenterWufeng(pop: 65,600)I: Not feltTaichung City, TaiwanTaiwan296 km (184 mi)W of epicenterCaotun(pop: 96,800)I: Not feltNantou, TaiwanTaiwan296 km (184 mi)W of epicenterZhongxing New Village(pop: 25,500)I: Not feltNantou, TaiwanTaiwan297 km (184 mi)W of epicenterTaichung(pop: 1,040,700)I: Not feltTaiwanTaiwan297 km (185 mi)W of epicenterXizhou(pop: 28,600)I: Not feltTaichung City, TaiwanTaiwan298 km (185 mi)W of epicenterZhushan(pop: 44,100)I: Not feltNantou, TaiwanTaiwan299 km (186 mi)W of epicenterNantou(pop: 105,700)I: Not feltTaiwanTaiwan307 km (191 mi)W of epicenterYuanlin(pop: 124,700)I: Not feltChanghua, TaiwanTaiwan308 km (192 mi)W of epicenterBuzi(pop: 40,500)I: Not feltTaichung City, TaiwanTaiwan310 km (193 mi)W of epicenterChanghua(pop: 226,600)I: Not feltTaiwanTaiwan313 km (194 mi)W of epicenterDouliu(pop: 104,700)I: Not feltYunlin, TaiwanTaiwan317 km (197 mi)W of epicenterXihu(pop: 47,000)I: Not feltChanghua, TaiwanTaiwan326 km (203 mi)W of epicenterChiayi City(pop: 263,200)I: Not feltChiayi, TaiwanTaiwan479 km (298 mi)NE of epicenterNaha(pop: 317,400)I: Not feltOkinawaJapanNotes:(*) 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 3 km2 (1 square miles) as a first-order estimate. The length of the rupture zone thus was probably around 3 km (2 mi).[More info]Recorded aftershocks, latest first (0 quake)Jul 2, 2025 05:55 am (GMT +9)5 minutes ago4.430 km0 km - This quakeSouthwestern Ryukyu Isl., JapanMain 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 370 quakes on average per year in the area near the epicenter of this quake (within 100 km/61 mi):Mag. 6 or higher: 0.21 quakes per year (or 1 quake every 4.8 years)Mag. 5 or higher: 2.3 quakes per yearMag. 4 or higher: 19.5 quakes per yearMag. 3 or higher: 28.7 quakes per yearMag. 2 or higher: 88 quakes per year (or 7.3 quakes per month)Mag. 1 or higher: 278 quakes per year (or 23.2 quakes per month)The area where this quake occurred has a very high level of seismic activity. It has had at least 26 quakes above magnitude 6 since 1900, which suggests that larger earthquakes of this size occur infrequently, probably on average approximately every 1 to 5 years.Number of quakes per yearPrevious quakes in the same area of this earthquake
