Indonesia's Meteorology, Climatology, and Geophysical Agency reported a magnitude 5.4 quake in Indonesia near Sarmi, Sarmi Regency, Provinsi Papua, only 7 minutes ago. The earthquake hit early morning on Tuesday, April 21st, 2026, at 3:47 am local time at a shallow depth of 10. km. 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.A second report was later issued by the German Research Centre for Geosciences (GFZ), which listed it as a magnitude 5.2 earthquake.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 Sarmi (pop. 14,100) located 59 km from the epicenter, the quake should have been felt as light shaking.VolcanoDiscovery will automatically update magnitude and depth if these change and follow up if other significant news about the quake become available.
