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 the Northern Mariana Islands, Saipan, 194 km (120 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(*)RegionCountry21 km (13 mi)S of epicenterYigo Village(pop: 20,500)III: WeakYigo Municipality Guam22 km (14 mi)S of epicenterDededo Village(pop: 44,900)III: WeakDededo Guam26 km (16 mi)S of epicenterTamuning-Tumon-Harmon Village(pop: 19,700)III: WeakTamuning Guam28 km (17 mi)S of epicenterBarrigada Village(pop: 8,880)III: WeakBarrigada Guam28 km (18 mi)S of epicenterMongmong-Toto-Maite Village(pop: 6,830)III: WeakMongmong-Toto-Maite Municipality Guam28 km (18 mi)S of epicenterHagatna(pop: 1,050)III: WeakHagatna Guam29 km (18 mi)S of epicenterAgana Heights Village(pop: 3,940)III: WeakAgana Heights Guam30 km (18 mi)S of epicenterSinajana Village(pop: 2,850)III: WeakSinajana Municipality Guam163 km (101 mi)NE of epicenterSan Jose(pop: 15,000)III: WeakTinian Municipality Northern Mariana Islands194 km (120 mi)NE of epicenterSaipan(pop: 48,200)III: WeakSaipan Northern Mariana Islands446 km (277 mi)N of epicenterPatik Camp(pop: 15)II: Very weakAlamagan Island, Northern Islands Northern Mariana Islands500 km (311 mi)N of epicenterPagan Village(pop: 50)II: Very weakPagan Island, Northern Islands Northern Mariana Islands565 km (351 mi)N of epicenterAgrihan Village(pop: 20)II: Very weakAgrihan Island, Northern Islands Northern Mariana Islands571 km (355 mi)S of epicenterFaraulep Village(pop: 221)II: Very weakFaraulep Municipality, State of Yap Micronesia643 km (400 mi)SW of epicenterFais(pop: 215)II: Very weakState of Yap Micronesia779 km (484 mi)SE of epicenterOnoun(pop: 580)I: Not feltState of Chuuk MicronesiaNotes:(*) Shaking intensity according to the Modified Mercalli Intensity Scale (MMI) and estimated using seismic models.User-reports for this quake (3)The first report about ground shaking reached us after only 48 seconds, before other agencies reported it. So far, we have received 3 reports for this quake from Guam. The quake was reported to have been felt in up to approx. 40 km (25 mi) distance.Most reports came from Hagatna (2 reports), the capital of Guam with 1,100 inhabitants in 28 km (18 mi) distance south of the epicenter, and Barrigada Village (1 report) (28 km or 17 mi to the south), a town with 8,900 inhabitants in Barrigada. Further below is a list of places where most people reported this quake.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!TranslateSanta rita, guam (38.7 km SSW of epicenter) [Map] / Light shaking (MMI IV) / horizontal (sideways) swinging / 15-20 s : I was on the ground of my living room area doing a workout and felt jolt first, then felt side to side shaking for at least 15 to 20 seconds. 38.5 km SSW of epicenter [Map] / Moderate shaking (MMI V) (reported through our app)Tamuning, Guam (26.2 km SSW of epicenter) [Map] / Light shaking (MMI IV) / 20-30 s (reported through our app)List of cities/places with most reportsPlaceDistance from epicenterAverage reported Shaking IntensityNr. of reportsHagatna, Hagatna, Guam(Pop.: 1,051)28 km (18 mi)S of epicenterV: Moderate shaking2Barrigada Village, Barrigada, Guam(Pop.: 8,875)28 km (17 mi)S of epicenterIV: Light shaking1Note: Only reports with latitude/longitude coordinate positions given (3 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 (*)IV: Light shaking226–39 km (16.3–24 mi)32 km (20 mi)V: Moderate shaking138–38 km (24–24 mi)38 km (24 mi)Notes(*) Reports are filtered to exclude those that are likely highly inaccurate or esaggerated.Only reports with latitude/longitude coordinate positions given (3 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 GMT2025-11-9EpicenterAgency5.3132 km82 mi22:53:41.99GUAM REGIONEMSC (European-Mediterranean Seismological Centre)5.57104 km65 mi22:53:38.86Mariana Islands9.6 km (5.9 mi) epicenter difference with EMSCGFZ (German Research Centre for Geosciences)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 20 km2 (8 square miles) as a first-order estimate. The length of the rupture zone thus was probably around 8 km (5 mi).[More info]Recorded aftershocks, latest first (0 quake)Nov 9, 2025 10:53 pm (Universal Time)8 minutes ago - felt5.3132 km0 km - This quake22 km N of Dededo Village, Dededo, GuamMain 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 56 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 62.5 years)Mag. 6 or higher: 0.13 quakes per year (or 1 quake every 7.9 years)Mag. 5 or higher: 3.4 quakes per yearMag. 4 or higher: 52 quakes per year (or 4.3 quakes per month)Mag. 3 or higher: 74 quakes per year (or 6.1 quakes per month)Mag. 2 or higher: 74 quakes per year (or 6.2 quakes per month)The area where this quake occurred has a very high level of seismic activity. It has had at least 2 quakes above magnitude 7 since 1900, which suggests that larger earthquakes of this size occur infrequently, probably on average approximately every 60 to 65 years.Number of quakes per yearPrevious quakes in the same area of this earthquake
