An earthquake of magnitude 4.9 occurred early Wednesday evening, September 30th, 2026, at 6:58 pm local time near Kupang, Kota Kupang, East Nusa Tenggara, Indonesia, according to Indonesia's Meteorology, Climatology, and Geophysical Agency.According to preliminary data, the quake occurred at a shallow depth of 10. km. Shallow earthquakes are felt more strongly than deeper ones because 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 the data and refine their calculations, or as other agencies issue their reports.A second report was later issued by the German Research Centre for Geosciences (GFZ), which listed it as a magnitude 5.0 earthquake. A third agency, the citizen-seismograph network RaspberryShake, reported the same quake at magnitude 5.0.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. Moderate shaking probably occurred in Kupang (pop. 442,800), located 11 km from the epicenter.Weak shaking might have been felt in Naisano Dua (pop. 2,300), located 56 km from the epicenter; Soe (pop. 40,200), 73 km away; Baa (pop. 1,300), 97 km away; and Kefamenanu (pop. 48,200), 115 km away.VolcanoDiscovery will automatically update the magnitude and depth if they change and follow up if other significant news about the quake becomes available.
