A powerful offshore earthquake has struck northeast Japan, triggering tsunami warnings and prompting evacuations along coastal regions.
The quake, initially measured at around 7.4–7.7 magnitude, hit off the Sanriku coast, with authorities warning of potential tsunami waves and urging residents to move to higher ground.
Tsunami Alerts Issued Across Northern Coast
Following the earthquake, the Japan Meteorological Agency issued tsunami warnings for parts of the northeast coast, including areas in Iwate, Aomori, and Hokkaido.
Authorities initially warned that waves of up to 3 meters could reach coastal areas, leading to evacuation orders affecting thousands of residents.
Waves Detected as Alerts Downgraded
Tsunami waves were later observed at lower heights, with reports of waves reaching around 80 centimeters, prompting officials to downgrade the warning to an advisory level.
Despite the reduced threat, officials urged people to stay away from the coast as aftershocks and additional waves remained possible.
Transport Disruptions and Emergency Measures
The earthquake caused widespread disruption, including the suspension of bullet train services and temporary road closures across affected regions.
Emergency teams were deployed, and evacuation centers were opened as a precaution while authorities assessed any damage to infrastructure and coastal communities.
Ongoing Risk of Aftershocks
Experts have warned of a slightly increased risk of a stronger earthquake in the coming days, although the likelihood remains low.
Japan, located along the Pacific “Ring of Fire,” frequently experiences seismic activity, and emergency systems responded quickly to minimise risk to residents.
Situation Being Closely Monitored
Authorities continue to monitor the situation closely as aftershocks remain possible and coastal areas stay under advisory alerts.
