According to Indonesia's Meteorology, Climatology, and Geophysical Agency, the quake hit on Monday, October 27th, 2025, at 1:04 am local time at an intermediate depth of 112. km. The strength of the earthquake may have been tempered by its relative great depth below the surface, which makes it feel weaker in absolute terms. 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 6.2 as well. Other agencies reporting the same quake include the citizen-seismograph network of RaspberryShake at magnitude 6.2, and the German Research Centre for Geosciences (GFZ) at magnitude 6.2.
Generally quakes of this magnitude are recorded by more than one agency and the results can vary, with subsequent reports that come in after the first one often showing more accuracy.
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 Naisano Dua (pop. 2,300) located 36 km from the epicenter, Kefamenanu (pop. 48,200) 57 km away, Soe (pop. 40,200) 67 km away, Kupang (pop. 442,800) 101 km away, and Atambua (pop. 82,200) 105 km away, the quake should have been felt as light shaking.
