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 (*)I: Not felt1274–274 km (170–170 mi)274 km (170 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.Get the Android appCompare 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 2 km2 (1 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)Jun 20, 2026 12:53 pm (GMT +9)36 minutes ago4.2307 km0 km - This quakeSea of Japan or East Sea, 10.1 km NW of Murakami, Niigata, JapanMain Shock (this quake)MoreMap of aftershocksEarthquake statisticsAverage number of earthquakesBased on data from the past 56 years and our earthquake archive back to 1900, there are about 363 quakes on average per year in the area near the epicenter of this quake (within 100 km/61 mi):Mag. 6 or higher: 0.04 quakes per year (or 1 quake every 25 years)Mag. 5 or higher: 0.32 quakes per year (or 1 quake every 3.1 years)Mag. 4 or higher: 3.8 quakes per yearMag. 3 or higher: 21.1 quakes per yearMag. 2 or higher: 64 quakes per year (or 5.3 quakes per month)Mag. 1 or higher: 152 quakes per year (or 12.7 quakes per month)The area where this quake occurred has a high level of seismic activity. It has had at least 5 quakes above magnitude 6 since 1900, which suggests that larger earthquakes of this size occur infrequently, probably on average approximately every 25 to 30 years.Number of quakes per yearPrevious quakes in the same area of this earthquakeThe earthquake occurred 18 weeks after a magnitude 4.8 earthquake had hit on Friday, Feb 13, 2026, at 01:58 pm (GMT +9 local time) in 69 km (43 mi) distance to the southwest:Mag. 4.8 earthquake 17 km southwest of Niigata - Niigata, Japan - Feb 13, 2026 - The largest quake near the epicenter of this quake during the 10 years before was an event of magnitude 7.5.
