People likely experienced 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, 114 km (71 mi) away from the epicenter, the earthquake was probably felt as weak shaking.The following table shows some of the places that might have been affected (or not) by the shaking.DistancePlaceMax. shaking intensity(*)RegionCountry6 km (4 mi)SW of epicenterHualien City(pop: 350,500)IV: LightHualien, TaiwanTaiwan67 km (42 mi)W of epicenterPuli(pop: 86,400)III: WeakNantou, TaiwanTaiwan82 km (51 mi)N of epicenterYilan(pop: 94,200)III: WeakTaiwanTaiwan95 km (59 mi)W of epicenterLugu(pop: 17,700)III: WeakNantou, TaiwanTaiwan95 km (59 mi)W of epicenterWufeng(pop: 65,600)III: WeakTaichung City, TaiwanTaiwan96 km (60 mi)W of epicenterCaotun(pop: 96,800)III: WeakNantou, TaiwanTaiwan96 km (60 mi)W of epicenterZhongxing New Village(pop: 25,500)III: WeakNantou, TaiwanTaiwan96 km (60 mi)W of epicenterZhongxing New Village(pop: 25,500)III: WeakNantou, TaiwanTaiwan97 km (60 mi)W of epicenterTaichung(pop: 1,040,700)III: WeakTaiwanTaiwan99 km (62 mi)W of epicenterNantou(pop: 105,700)III: WeakTaiwanTaiwan99 km (62 mi)W of epicenterXizhou(pop: 28,600)III: WeakTaichung City, TaiwanTaiwan101 km (63 mi)N of epicenterDaxi(pop: 94,200)III: WeakTaoyuan, TaiwanTaiwan101 km (63 mi)W of epicenterZhushan(pop: 44,100)III: WeakNantou, TaiwanTaiwan103 km (64 mi)NW of epicenterToufen Township(pop: 106,300)III: WeakMiaoli, TaiwanTaiwan104 km (65 mi)N of epicenterSanxia(pop: 115,200)III: WeakNew Taipei City, TaipeiTaiwan106 km (66 mi)N of epicenterBade(pop: 209,100)III: WeakTaoyuan, TaiwanTaiwan107 km (66 mi)N of epicenterYingge(pop: 87,900)III: WeakNew Taipei City, TaipeiTaiwan107 km (66 mi)W of epicenterShetou(pop: 36,600)III: WeakChanghua, TaiwanTaiwan107 km (67 mi)W of epicenterYuanlin(pop: 124,700)III: WeakChanghua, TaiwanTaiwan108 km (67 mi)W of epicenterTianzhong(pop: 34,900)III: WeakChanghua, TaiwanTaiwan109 km (68 mi)N of epicenterShulin(pop: 180,000)III: WeakNew Taipei City, TaipeiTaiwan109 km (68 mi)NW of epicenterHsinchu(pop: 404,100)III: WeakTaiwanTaiwan109 km (68 mi)W of epicenterBuzi(pop: 40,500)III: WeakTaichung City, TaiwanTaiwan110 km (68 mi)W of epicenterChanghua(pop: 226,600)III: WeakTaiwanTaiwan111 km (69 mi)N of epicenterBanqiao(pop: 543,300)III: WeakNew Taipei City, TaipeiTaiwan111 km (69 mi)W of epicenterYongjing(pop: 35,400)III: WeakChanghua, TaiwanTaiwan112 km (70 mi)N of epicenterTaoyuan City(pop: 402,000)III: WeakTaoyuan, TaiwanTaiwan114 km (71 mi)W of epicenterBeidou(pop: 33,300)III: WeakChanghua, TaiwanTaiwan114 km (71 mi)N of epicenterTaipei(pop: 7,871,900)III: WeakTaiwanTaiwan115 km (72 mi)N of epicenterXizhi(pop: 204,600)III: WeakNew Taipei City, TaipeiTaiwan116 km (72 mi)N of epicenterNew Taipei City(pop: 4,004,400)III: WeakNew Taipei City, TaipeiTaiwan116 km (72 mi)W of epicenterDouliu(pop: 104,700)III: WeakYunlin, TaiwanTaiwan117 km (73 mi)N of epicenterNeihu(pop: 271,600)III: WeakTaipei City, TaiwanTaiwan117 km (73 mi)W of epicenterXihu(pop: 47,000)III: WeakChanghua, TaiwanTaiwan121 km (75 mi)W of epicenterXiluo(pop: 37,200)III: WeakYunlin, TaiwanTaiwan123 km (76 mi)N of epicenterKeelung(pop: 397,500)III: WeakTaiwanTaiwan128 km (80 mi)N of epicenterDanshui(pop: 189,300)III: WeakNew Taipei City, TaipeiTaiwan129 km (80 mi)W of epicenterErlin(pop: 43,700)III: WeakChanghua, TaiwanTaiwan135 km (84 mi)SW of epicenterChiayi City(pop: 263,200)III: WeakChiayi, TaiwanTaiwan150 km (93 mi)S of epicenterTaitung(pop: 103,300)II: Very weakTaiwanTaiwanNotes:(*) Shaking intensity according to the Modified Mercalli Intensity Scale (MMI) and estimated using seismic models.User-reports for this quake (1)The first report about ground shaking reached us after only 6 minutes, before other agencies reported it. So far, we have received 1 report for this quake from Taiwan.It came from near Taipei, the capital of Taiwan with 7,900,000 inhabitants in Taiwan in 114 km (71 mi) distance north of the epicenter.This section is being updated as new data comes in.User reports estimate the perceived ground shaking intensity according to the MMI (Modified Mercalli Intensity) scale.Contribute:Leave a comment if you find a particular report interesting or want to add to it.Flag as inappropriate.Mark as helpful or interesting.Send your own user report!Translate116.4 km N of epicenter [Map] / Very weak shaking (MMI II) / single lateral shake / 2-5 s : Пару толчков List of cities/places with most reportsPlaceDistance from epicenterAverage reported Shaking IntensityNr. of reportsTaipei, Taiwan, Taiwan(Pop.: 7,871,900)114 km (71 mi)N of epicenterII: Very weak shaking1Note: Only reports with latitude/longitude coordinate positions given (1 in total) could be used for statistics.What is Intensity and the Mercalli Intensity Scale?The amount of shaking that occurs on the surface due to an earthquake is called the intensity. It is commonly measured on the so-called Modified Mercalli Intensity Scale (MMI) ranging from 1 (not felt) to 10 (extreme shaking), and given in Roman numerals as I,II,...IX, X, and often displayed with color codes ranging from light blue to dark red.Earthquake intensity depends mainly on the magnitude and depth of the quake as well as the distance from the epicenter: The further away, the less shaking intensity occurs.Read more about the MMI scale!Number of reports by intensityShaking intensityNumber of reportsMin-Max distance from epicenter (*)Average distance (*)II: Very weak shaking1116–116 km (72–72 mi)116 km (72 mi)Notes(*) Reports are filtered to exclude those that are likely highly inaccurate or esaggerated.Only reports with latitude/longitude coordinate positions given (1 in total) could be used for geographic statistics.I didn't feel itI felt this quakeIf you were near the epicenter and felt it, please share your experience and submit a short "I felt it" report!

Your contribution is valuable to earthquake science and seismic hazard analysis.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. It takes normally up to a few hours until earthquake parameters are calculated with near-optimum precision.MagDepthTime GMT2025-09-18EpicenterAgency4.723 km14 mi21:21:41TaiwanRaspberryShake (RaspberryShake)Aftershocks for this quakeNo aftershocks have been recorded so far. 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 5 km2 (2 square miles) as a first-order estimate. The length of the rupture zone thus was probably around 4 km (2 mi).[More info]Recorded aftershocks, latest first (0 quake)Sep 18, 2025 09:21 pm (Universal Time)7 minutes ago4.723 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 361 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: 1.25 quakes per yearMag. 5 or higher: 11.1 quakes per yearMag. 4 or higher: 157 quakes per year (or 13.1 quakes per month)Mag. 3 or higher: 245 quakes per year (or 20.4 quakes per month)Mag. 2 or higher: 346 quakes per year (or 28.8 quakes per month)Mag. 1 or higher: 354 quakes per year (or 29.5 quakes per month)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
