Significant earthquake of magnitude 5.1 just reported 122 km southwest of Baturaja, Indonesia
5.1 quake 27 Jan 5:40 pm (GMT +7)
5.1 quake 27 Jan 5:40 pm (GMT +7)
A shallow magnitude 5.1 earthquake was reported in the afternoon near Baturaja, Sumatera Selatan, Indonesia.
According to Indonesia's Meteorology, Climatology, and Geophysical Agency (BMKG), the quake hit on Wednesday 27 January 2021 at 5:40 pm local time at a shallow depth of 10 km. 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.
A second report was later issued by the German Research Centre for Geosciences (GFZ), which listed it as a magnitude 4.8 earthquake. Other agencies reporting the same quake include United States Geological Survey (USGS) at magnitude 4.8, and European-Mediterranean Seismological Centre (EMSC) at magnitude 4.8.
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 Baturaja (pop. 134,800) located 122 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.
