4.8 quake 27 Jan 11:13 am (GMT +8)
Just 11 minutes ago, a 4.8-magnitude earthquake struck near Kupang, East Nusa Tenggara, Indonesia. The tremor was recorded in the morning on Wednesday 27 January 2021 at 11:13 am local time, at a shallow depth of 10 km below the surface.
The event was filed by Indonesia's Meteorology, Climatology, and Geophysical Agency (BMKG), the first seismological agency to report it.
Our monitoring service identified a second report from the United States Geological Survey (USGS) which listed the quake at magnitude 4.9. A third agency, the European-Mediterranean Seismological Centre (EMSC), reported the same quake at magnitude 4.9.
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 Kupang (pop. 282,400) located 36 km from the epicenter, and Soe (pop. 27,700) 80 km away.
VolcanoDiscovery will automatically update magnitude and depth if these change and follow up if other significant news about the quake become available. If you're in the area, please send us your experience through our reporting mechanism, either online or via our mobile app. This will help us provide more first-hand updates to anyone around the globe who wants to know more about this quake.
