A shallow magnitude 4.9 earthquake was reported after midnight near Sarmi, Sarmi Regency, Provinsi Papua, Indonesia.According to the United States Geological Survey, the quake hit on Tuesday, July 28th, 2026, at 12:51 am 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. Magnitude and other quake parameters can still change in the coming hours as the agency continues to process seismic data.A second report was later issued by the European-Mediterranean Seismological Centre (EMSC), which listed it as a magnitude 4.3 earthquake. Other agencies reporting the same quake include the citizen-seismograph network of RaspberryShake at magnitude 4.9, and Indonesia's Meteorology, Climatology, and Geophysical Agency 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 Sarmi (pop. 14,100) located 78 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.
