Indonesia's Meteorology, Climatology, and Geophysical Agency reported a magnitude 5.2 quake in Japan near Azumino, Azumino-Shi, Nagano, only 15 minutes ago. The earthquake hit early afternoon on Thursday, January 15th, 2026, at 2:48 pm local time at an intermediate depth of 85. 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 4.9 earthquake. Other agencies reporting the same quake include the citizen-seismograph network of RaspberryShake at magnitude 4.9, and France's Réseau National de Surveillance Sismique (RéNaSS) at magnitude 5.0.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 Azumino (pop. 94,200) located 15 km from the epicenter, Matsumoto (pop. 241,100) 21 km away, Takayama (pop. 88,500) 45 km away, Ueda (pop. 157,500) 52 km away, Nagano (pop. 372,800) 60 km away, Saku (pop. 99,100) 68 km away, Imizu (pop. 90,700) 79 km away, and Iida (pop. 101,500) 82 km away.VolcanoDiscovery will automatically update magnitude and depth if these change and follow up if other significant news about the quake become available.
