The earthquake hit early morning on Sunday, August 23rd, 2026, at 3:54 am local time at an intermediate depth of 86. 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 not have caused any significant damage, but was probably felt by many people as light vibration in the area of the epicenter.Weak shaking might have been felt in Luwuk (pop. 47,800) located 79 km from the epicenter, and Gorontalo (pop. 198,500) 92 km away.VolcanoDiscovery will automatically update magnitude and depth if these change and follow up if other significant news about the quake become available.

The length of the rupture zone thus was probably around 7 km (4 mi).[More info]Recorded aftershocks, latest first (0 quake)Aug 23, 2026 03:54 am (GMT +8)12 minutes ago5.2158 km0 km - This quake88 km N of Luwuk, Kabupaten Banggai, Sulawesi Tengah, 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 352 quakes on average per year in the area near the epicenter of this quake (within 100 km/61 mi):Mag. 7 or higher: 0.02 quakes per year (or 1 quake every 62.5 years)Mag. 6 or higher: 0.21 quakes per year (or 1 quake every 4.9 years)Mag. 5 or higher: 4.1 quakes per yearMag. 4 or higher: 50 quakes per year (or 4.2 quakes per month)Mag. 3 or higher: 201 quakes per year (or 16.7 quakes per month)Mag. 2 or higher: 350 quakes per year (or 29.2 quakes per month)Mag. 1 or higher: 352 quakes per year (or 29.4 quakes per month)The area where this quake occurred has a very high level of seismic activity. It has had at least 2 quakes above magnitude 7 since 1900, which suggests that larger earthquakes of this size occur infrequently, probably on average approximately every 60 to 65 years.Number of quakes per yearPrevious quakes in the same area of this earthquake
