The European-Mediterranean Seismological Centre (EMSC) reported a magnitude 5.1 quake in Japan near Yaese, Shimajiri-gun, Okinawa, only 15 minutes ago. The earthquake hit early morning on Saturday, June 20th, 2026, at 4:36 am local time at a shallow depth of 28. 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.Our monitoring service identified a second report from Indonesia's Meteorology, Climatology, and Geophysical Agency which listed the quake at magnitude 4.9. Other agencies reporting the same quake include the citizen-seismograph network of RaspberryShake at magnitude 5.1, and the German Research Centre for Geosciences (GFZ) at magnitude 5.1.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 Yaese (pop. 30,900) located 120 km from the epicenter, Nanjo (pop. 44,000) 121 km away, and Itoman (pop. 61,000) 122 km away.VolcanoDiscovery will automatically update magnitude and depth if these change and follow up if other significant news about the quake become available.
