A magnitude 5.2 earthquake near Minami-Soma, Minamisōma Shi, Fukushima, Japan, was reported only 18 minutes ago by the German Research Centre for Geosciences (GFZ), considered one of the key international agencies that monitor seismic activity worldwide. The earthquake occurred at a shallow depth of 10. km beneath the epicenter early morning on Friday, October 24th, 2025, at 6:09 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 France’s Réseau National de Surveillance Sismique (RéNaSS), which listed it as a magnitude 5.1 earthquake. Other agencies reporting the same quake include Japan’s National Research Institute for Earth Science and Disaster Resilience (NIED) at magnitude 5.2, and the citizen-seismograph network of RaspberryShake at magnitude 5.2.
Generally quakes of this magnitude are recorded by more than one agency and the results can vary, with subsequent reports that come in after the first one often showing more accuracy.
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

Map of today’s active volcanoes

Svartsengi (Reykjanes peninsula, SW Iceland): The Icelandic Meteorological Office (IMO) reported that by 23 September around 10 million cubic meters of magma had accumulated beneath Svartsengi since the last eruption within the Reykjanes volcanic system ended on 5 August. Data showed that magma was accumulating at around 4 km depth. The rate of magma accumulation was steady; model calculations based on deformation measurements indicated that by 27 September the volume may reach 11 million cubic meters, a volume that in some previous cases was followed by eruptions.
Since the likelihood of an eruption had increased, IMO raised the Volcanic Alert Level System (VAL) to 2 (on a scale of 0-3) on 25 September and concurrently a risk assessment map of the area was also updated.
