Out of these, 1 people indicated they felt it. The quake was reported to have been felt in up to approx. 30 km (19 mi) distance.Most reports came from Cicurug, a town with 89,000 inhabitants in West Java in 37 km (23 mi) distance northwest of the epicenter, Indonesia.

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 felt151–51 km (32–32 mi)51 km (32 mi)IV: Light shaking129–29 km (18.1–18.1 mi)29 km (18 mi)Notes(*) Reports are filtered to exclude those that are likely highly inaccurate or esaggerated.Only reports with latitude/longitude coordinate positions given (2 in total) could be used for geographic statistics.Get the Android appI 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.

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 (2 mi).[More info]Recorded aftershocks, latest first (0 quake)Sep 1, 2026 05:53 pm (Jakarta)17 minutes ago4.310 km0 km - This quake11 km SW of Cianjur, Kabupaten Cianjur, West Java, IndonesiaMain 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 187 quakes on average per year in the area near the epicenter of this quake (within 100 km/61 mi):Mag. 6 or higher: 0.06 quakes per year (or 1 quake every 15.9 years)Mag. 5 or higher: 1.4 quakes per yearMag. 4 or higher: 12.8 quakes per yearMag. 3 or higher: 61 quakes per year (or 5.1 quakes per month)Mag. 2 or higher: 181 quakes per year (or 15.1 quakes per month)Mag. 1 or higher: 187 quakes per year (or 15.6 quakes per month)The area where this quake occurred has a high level of seismic activity. It has had at least 8 quakes above magnitude 6 since 1900, which suggests that larger earthquakes of this size occur infrequently, probably on average approximately every 15 to 20 years.Number of quakes per yearPrevious quakes in the same area of this earthquake
