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 Taiwan, Taipei, 125 km (78 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(*)RegionCountry15 km (9 mi)E of epicenterHualien City(pop: 350,500)III: WeakHualien, TaiwanTaiwan51 km (32 mi)W of epicenterPuli(pop: 86,400)III: WeakNantou, TaiwanTaiwan76 km (47 mi)W of epicenterLugu(pop: 17,700)II: Very weakNantou, TaiwanTaiwan80 km (49 mi)W of epicenterCaotun(pop: 96,800)II: Very weakNantou, TaiwanTaiwan80 km (50 mi)W of epicenterWufeng(pop: 65,600)II: Very weakTaichung City, TaiwanTaiwan80 km (50 mi)W of epicenterZhongxing New Village(pop: 25,500)II: Very weakNantou, TaiwanTaiwan82 km (51 mi)W of epicenterNantou(pop: 105,700)II: Very weakTaiwanTaiwan82 km (51 mi)W of epicenterZhushan(pop: 44,100)II: Very weakNantou, TaiwanTaiwan83 km (52 mi)W of epicenterTaichung(pop: 1,040,700)II: Very weakTaiwanTaiwan88 km (55 mi)W of epicenterErshui(pop: 14,100)II: Very weakChanghua, TaiwanTaiwan88 km (55 mi)NW of epicenterXizhou(pop: 28,600)II: Very weakTaichung City, TaiwanTaiwan89 km (55 mi)W of epicenterLinnei(pop: 16,900)II: Very weakYunlin, TaiwanTaiwan90 km (56 mi)W of epicenterShetou(pop: 36,600)II: Very weakChanghua, TaiwanTaiwan90 km (56 mi)W of epicenterTianzhong(pop: 34,900)II: Very weakChanghua, TaiwanTaiwan91 km (57 mi)W of epicenterYuanlin(pop: 124,700)II: Very weakChanghua, TaiwanTaiwan94 km (58 mi)W of epicenterYongjing(pop: 35,400)II: Very weakChanghua, TaiwanTaiwan95 km (59 mi)W of epicenterChanghua(pop: 226,600)II: Very weakTaiwanTaiwan96 km (60 mi)W of epicenterBuzi(pop: 40,500)II: Very weakTaichung City, TaiwanTaiwan96 km (60 mi)W of epicenterTianwei(pop: 26,100)II: Very weakChanghua, TaiwanTaiwan96 km (60 mi)N of epicenterYilan(pop: 94,200)II: Very weakTaiwanTaiwan96 km (60 mi)W of epicenterBeidou(pop: 33,300)II: Very weakChanghua, TaiwanTaiwan97 km (61 mi)W of epicenterDouliu(pop: 104,700)II: Very weakYunlin, TaiwanTaiwan101 km (63 mi)W of epicenterXihu(pop: 47,000)II: Very weakChanghua, TaiwanTaiwan102 km (63 mi)NW of epicenterToufen Township(pop: 106,300)II: Very weakMiaoli, TaiwanTaiwan103 km (64 mi)W of epicenterXiluo(pop: 37,200)II: Very weakYunlin, TaiwanTaiwan108 km (67 mi)N of epicenterDaxi(pop: 94,200)II: Very weakTaoyuan, TaiwanTaiwan110 km (68 mi)NW of epicenterHsinchu(pop: 404,100)II: Very weakTaiwanTaiwan112 km (70 mi)W of epicenterErlin(pop: 43,700)II: Very weakChanghua, TaiwanTaiwan112 km (70 mi)N of epicenterSanxia(pop: 115,200)II: Very weakNew Taipei City, TaipeiTaiwan113 km (70 mi)N of epicenterBade(pop: 209,100)II: Very weakTaoyuan, TaiwanTaiwan115 km (71 mi)N of epicenterYingge(pop: 87,900)II: Very weakNew Taipei City, TaipeiTaiwan115 km (72 mi)SW of epicenterChiayi City(pop: 263,200)II: Very weakChiayi, TaiwanTaiwan118 km (73 mi)N of epicenterShulin(pop: 180,000)II: Very weakNew Taipei City, TaipeiTaiwan120 km (74 mi)N of epicenterTaoyuan City(pop: 402,000)II: Very weakTaoyuan, TaiwanTaiwan121 km (75 mi)N of epicenterBanqiao(pop: 543,300)II: Very weakNew Taipei City, TaipeiTaiwan125 km (78 mi)N of epicenterTaipei(pop: 7,871,900)II: Very weakTaiwanTaiwan126 km (78 mi)N of epicenterNew Taipei City(pop: 4,004,400)II: Very weakNew Taipei City, TaipeiTaiwan129 km (80 mi)N of epicenterNeihu(pop: 271,600)II: Very weakTaipei City, TaiwanTaiwan134 km (83 mi)S of epicenterTaitung(pop: 103,300)II: Very weakTaiwanTaiwan136 km (85 mi)N of epicenterKeelung(pop: 397,500)II: Very weakTaiwanTaiwanNotes:(*) 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)Aug 26, 2025 10:56 am (Universal Time)6 minutes ago4.018 km0 km - This quakeTaiwanMain 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 326 quakes on average per year in the area near the epicenter of this quake (within 100 km/61 mi):Mag. 7 or higher: 0.11 quakes per year (or 1 quake every 9.3 years)Mag. 6 or higher: 1.13 quakes per yearMag. 5 or higher: 9.5 quakes per yearMag. 4 or higher: 147 quakes per year (or 12.2 quakes per month)Mag. 3 or higher: 235 quakes per year (or 19.6 quakes per month)Mag. 2 or higher: 315 quakes per year (or 26.2 quakes per month)Mag. 1 or higher: 5,300 quakes per year (or 14.6 quakes per day)The area where this quake occurred has a very high level of seismic activity. It has had at least 14 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
