The depth of the quake could not be determined, but is assumed to be shallow.The quake was reported felt by some people near the epicenter.Quake Data | Interactive map | Seismograms | User reports | Aftershocks | Earlier quakes here | Quakes in Indonesia | Sulawesi Tengah | Gorontalo | Provinsi Sulawesi SelatanHint: Click on the image to see different maps of this quake!Strong magnitude 5.3 earthquake at unknown depth21 Sep 07:35 UTC: First to report: BMKG after 4 minutes.Update Mon, 21 Sep 2026, 07:36Significant magnitude 5.3 earthquake 47 km northwest of Luwuk, IndonesiaIndonesia's Meteorology, Climatology, and Geophysical Agency reported a magnitude 5.3 quake in Indonesia near Luwuk, Banggai Regency, Sulawesi Tengah, only 5 minutes ago. The earthquake hit early afternoon on Monday, September 21st, 2026, at 3:31 pm 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 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 Luwuk (pop. 47,800) located 47 km from the epicenter.VolcanoDiscovery will automatically update magnitude and depth if these change and follow up if other significant news about the quake become available.
