Magnitude 5.1 Earthquake Strikes Near Nakanoshima, Japan

A magnitude 5.1 earthquake struck approximately 104 kilometers southeast of Nakanoshima, Kagoshima-gun, Kagoshima-ken, Japan, on Wednesday, February 18, 2026, at 11:27 am local time (2:27 GMT). The quake occurred at a shallow depth of 10 kilometers.

Details of the Earthquake

The German Research Centre for Geosciences (GFZ) initially reported the earthquake. France’s Réseau National de Surveillance Sismique (RéNaSS) also reported a magnitude of 5.1, while the citizen-seismograph network of RaspberryShake recorded a magnitude of 5.2.

Impact and Potential Damage

Based on preliminary seismic data, significant damage is not expected. However, the earthquake was likely felt as a light vibration in the epicenter area. Weak shaking may have been felt in Nakanoshima, which has a population of approximately 740.

Ongoing Monitoring and Updates

Seismologists are continuing to review data and refine calculations of the earthquake’s magnitude, epicenter, and depth. VolcanoDiscovery will provide updates as more information becomes available. Residents in the affected area are encouraged to report their experiences through VolcanoDiscovery’s online reporting mechanism or mobile app.

Regional Seismic Activity

A recent report from VolcanoDiscovery indicates moderate global seismic activity, with five earthquakes of magnitude 5.0 or greater, 36 earthquakes of magnitude 4.0 or greater, and 105 earthquakes of magnitude 3.0 or greater occurring in the past 24 hours. The largest earthquake during this period was a magnitude 5.2 quake in the Banda Sea.
