An earthquake of magnitude 5.2 occurred only 9 minutes ago 70 km northeast of Iwaki, Japan, Japan’s National Research Institute for Earth Science and Disaster Resilience (NIED) reported.
The quake hit at a moderately shallow depth of 41.70 km beneath the epicenter near Iwaki, Iwaki-shi, Fukushima, Japan, early morning on Saturday, August 30th, 2025, at 1:51 am local time. 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 citizen-seismograph network of RaspberryShake, which listed it as a magnitude 4.7 earthquake.
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 Minami-Soma (pop. 59,000) located 67 km from the epicenter, Iwaki (pop. 357,300) 70 km away, Soma (pop. 34,900) 81 km away, Tamura (pop. 35,200) 90 km away, Kitaibaraki (pop. 41,800) 95 km away, Koriyama (pop. 327,700) 109 km away, Fukushima (pop. 294,200) 113 km away, and Fukushima (pop. 294,200) 113 km away.
