The quake had a very shallow depth of 26 km (16 mi) and was not felt (or at least not reported so).Quake Data | Interactive map | Seismograms | User reports | Aftershocks | Earlier quakes here | Quakes in Indonesia | Quakes in Thailand | Nanggroe Aceh Darussalam Province | North Sumatra | PhuketHint: Click on the image to see different maps of this quake!Strong magnitude 5.9 earthquake at 26 km depth3 Oct 23:41 UTC: First to report: BMKG after 4 minutes.Update Sat, 3 Oct 2026, 23:42Significant magnitude 5.9 quake hits 117 km southwest of Banda Aceh, Indonesia early morningA magnitude 5.9 earthquake near Banda Aceh, Kota Banda Aceh, Nanggroe Aceh Darussalam Province, Indonesia, was reported only 5 minutes ago by Indonesia's Meteorology, Climatology, and Geophysical Agency, considered the main national agency that monitors seismic activity in Indonesia. The earthquake occurred at a shallow depth of 26. km beneath the epicenter early morning on Sunday, October 4th, 2026, at 5:37 am local time. 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 was probably felt by many people in the area of the epicenter. It should not have caused significant damage, other than objects falling from shelves, broken windows, etc.Weak shaking might have been felt in Banda Aceh (pop. 255,000) located 117 km from the epicenter, Meulaboh (pop. 64,600) 131 km away, and Sigli (pop. 17,500) 141 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!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 79 km2 (31 square miles) as a first-order estimate. The length of the rupture zone thus was probably around 15 km (10 mi).[More info]Recorded aftershocks, latest first (0 quake)Oct 4, 2026 05:37 am (GMT +6)5 minutes ago5.926 km0 km - This quakeIndian Ocean, 117 km S of Banda Aceh, 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 43 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: 3.8 quakes per yearMag. 4 or higher: 11.7 quakes per yearMag. 3 or higher: 29.3 quakes per yearMag. 2 or higher: 45 quakes per year (or 3.7 quakes per month)The area where this quake occurred has a high level of seismic activity.
