Indonesia was shaken near Luwuk, Kabupaten Banggai, Central Sulawesi, by an earthquake of magnitude 5.9 only 11 minutes ago, Indonesia's Meteorology, Climatology, and Geophysical Agency reported.
The quake hit at a shallow depth of 10 km beneath the epicenter near Luwuk, Kabupaten Banggai, Central Sulawesi, Indonesia, in the morning on Monday 26 July 2021 at 11:52 am local time. Shallow earthquakes are felt more strongly than deeper ones as they are closer to the surface. 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.
Our monitoring service identified a second report from the European-Mediterranean Seismological Centre (EMSC) which listed the quake at magnitude 5.9 as well. A third agency, the German Research Centre for Geosciences (GFZ), reported the same quake at magnitude 5.8.
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.
In Luwuk (pop. 47,800) located 105 km from the epicenter, the quake should have been felt as light shaking.
Weak shaking might have been felt in Poso (pop. 47,100) located 145 km from the epicenter.
