The quake had a shallow depth of 67 km (42 mi) and was felt by many near the epicenter. The shallow depth of the quake caused it to be felt more strongly near the epicenter than a deeper quake of similar magnitude would.Quake Data | Interactive map | Seismograms | User reports | Aftershocks | Earlier quakes here | Quakes in Indonesia | East Nusa Tenggara | West Nusa Tenggara | BaliHint: Click on the image to see different maps of this quake!Strong magnitude 5.8 earthquake at 67 km depth3 Oct 22:58 UTC: First to report: VolcanoDiscovery after 2 minutes.3 Oct 22:59: Now using data updates from BMKG...

The earthquake hit early morning on Sunday, October 4th, 2026, at 6:55 am local time at a shallow depth of 10. km. The exact magnitude, epicenter, and depth of the quake might be revised within the next few hours or minutes as seismologists review data and refine their calculations, or as other agencies issue their report.Based on the preliminary seismic data, the quake should have been widely felt by almost everyone in the area of the epicenter. It might have caused light to moderate damage.Moderate shaking probably occurred in Tambolaka (pop. 35,800) located 38 km from the epicenter.Weak shaking might have been felt in Bima (pop. 161,400) located 129 km from the epicenter, Dompu (pop. 55,000) 129 km away, and Waingapu (pop. 35,900) 145 km away.VolcanoDiscovery will automatically update magnitude and depth if these change and follow up if other significant news about the quake become available.

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 felt21,396–1,397 km (867–868 mi)1,397 km (868 mi)II: Very weak shaking2305–424 km (190–264 mi)365 km (227 mi)III: Weak shaking6108–426 km (67–265 mi)269 km (167 mi)IV: Light shaking56.6–499 km (4.1–310 mi)185 km (115 mi)Notes(*) Reports are filtered to exclude those that are likely highly inaccurate or esaggerated.Only reports with latitude/longitude coordinate positions given (19 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!

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 63 km2 (24 square miles) as a first-order estimate. The length of the rupture zone thus was probably around 14 km (9 mi).[More info]Recorded aftershocks, latest first (0 quake)Oct 3, 2026 10:55 pm (Universal Time)16 minutes ago - felt5.867 km0 km - This quakeIndian Ocean, 37 km SW of Tambolaka, IndonesiaMain Shock (this quake)MoreMap of aftershocksEarthquake statisticsAverage number of earthquakesBased on data from the past 26 years and our earthquake archive back to 1900, there are about 454 quakes on average per year in the area near the epicenter of this quake (within 100 km/61 mi):Mag. 6 or higher: 0.16 quakes per year (or 1 quake every 6.3 years)Mag. 5 or higher: 2.8 quakes per yearMag. 4 or higher: 39.2 quakes per year (or 3.3 quakes per month)Mag. 3 or higher: 167 quakes per year (or 13.9 quakes per month)Mag. 2 or higher: 450 quakes per year (or 37.5 quakes per month)Mag. 1 or higher: 453 quakes per year (or 37.8 quakes per month)The area where this quake occurred has a very high level of seismic activity. It has had at least 20 quakes above magnitude 6 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
