So far, we have received 1 report for this unconfirmed quake from Japan.It came from near Tokyo, the capital of Japan with 8,300,000 inhabitants in 9.4 km (5.9 mi) distance west 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!Translate0 km N of epicenter [Map] / Very weak shaking (MMI II) / horizontal (sideways) swinging / 1-2 s : Brief sideways shaking List of cities/places with most reportsPlaceDistance from epicenterAverage reported Shaking IntensityNr. of reportsTokyo, Tokyo, Japan(Pop.: 8,336,599)9.4 km (5.9 mi)W 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 shaking10–0 km (0–0 mi)0 km (0 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! Other users would love to hear about it!If you did NOT feel the quake although you were in the area, please report it as well! 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 GMT2025-10-7EpicenterAgency3.010 km6.2 mi(*)00:32:02Near Tokyo, Tokyo, JapanVolcanoDiscovery (User-reported shaking)Notes:(*) A depth given as 10 km often means that the the depth of the quake could be not determined with sufficient accuracy.Earthquake statisticsAverage number of earthquakesBased on data from the past 25 years and our earthquake archive back to 1900, there are about 2,700 quakes on average per year in the area near the epicenter of this quake (within 100 km/61 mi):Mag. 7 or higher: 0.04 quakes per year (or 1 quake every 25 years)Mag. 6 or higher: 0.3 quakes per year (or 1 quake every 3.3 years)Mag. 5 or higher: 4.7 quakes per yearMag. 4 or higher: 52 quakes per year (or 4.3 quakes per month)Mag. 3 or higher: 159 quakes per year (or 13.2 quakes per month)Mag. 2 or higher: 440 quakes per year (or 36.6 quakes per month)Mag. 1 or higher: 1,300 quakes per year (or 3.6 quakes per day)The area where this quake occurred has a very high level of seismic activity. It has had at least 5 quakes above magnitude 7 since 1900, which suggests that larger earthquakes of this size occur infrequently, probably on average approximately every 23 to 27 years.Number of quakes per yearPrevious quakes in the same area of this earthquake
