An earthquake of magnitude 5.6 occurred in the morning on Tuesday, August 19th, 2025, at 7:19 am local time near Hakodate, Hakodate Shi, Hokkaido, Japan, as reported by Japan’s National Research Institute for Earth Science and Disaster Resilience (NIED).
According to preliminary data, the quake was located at an intermediate depth of 131.90 km. The strength of the earthquake may have been tempered by its relative great depth below the surface, which makes it feel weaker in absolute terms. 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.
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 Higashimoricho (pop. 14,300) located 12 km from the epicenter, Honcho (pop. 28,500) 13 km away, Kamiiso (pop. 38,100) 22 km away, Hokuto (pop. 46,100) 22 km away, Hakodate (pop. 275,700) 27 km away, Yakumo (pop. 15,800) 43 km away, Muroran (pop. 96,200) 43 km away, Date (pop. 34,900) 53 km away, and Sapporo (pop. 1,973,800) 130 km away.
