An earthquake of magnitude 5.7 occurred just 8 minutes ago, 81 km southeast of Madang, Papua New Guinea, according to Indonesia's Meteorology, Climatology, and Geophysical Agency.The quake struck at an intermediate depth of 102. km beneath the epicenter near Madang, Madang Province, Papua New Guinea, late Sunday night, September 20th, 2026, at 10:45 pm local time. 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.Our monitoring service identified a second report from France's Réseau National de Surveillance Sismique (RéNaSS), which listed the quake at magnitude 5.4. Other agencies reporting the same quake include the citizen-seismograph network RaspberryShake, which reported a magnitude of 5.7, and the German Research Centre for Geosciences (GFZ), which also reported a magnitude of 5.7.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 greater accuracy.Based on the preliminary seismic data, the quake should not have caused any significant damage, but it was probably felt by many people as light vibrations in the epicentral area. Weak shaking might have been felt in Kainantu (pop. 8,500), located 62 km from the epicenter; Madang (pop. 27,400), 81 km away; Goroka (pop. 18,500), 93 km away; Lae (pop. 76,300), 133 km away; and Kundiawa (pop. 9,400), 137 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.
