An earthquake of magnitude 5.0 occurred only 19 minutes ago 101 km west of Waingapu, Indonesia, the German Research Centre for Geosciences (GFZ) reported.
The quake hit at a shallow depth of 10 km beneath the epicenter near Waingapu, East Nusa Tenggara, Indonesia, early morning on Wednesday 4 August 2021 at 3:44 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.
A second report was later issued by the United States Geological Survey, which listed it as a magnitude 4.8 earthquake. A third agency, the European-Mediterranean Seismological Centre (EMSC), reported the same quake at magnitude 5.0.
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 Waingapu (pop. 48,800) located 101 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.
