Powerful Earthquake Strikes North-Eastern Japan, Injuring Dozens and Triggering Tsunami Warnings

In This Article
HIGHLIGHTS
- A magnitude 7.5 earthquake struck north-eastern Japan, injuring at least 30 people and prompting evacuation orders for 90,000 residents.
- The quake's epicenter was 80km off the coast of the Aomori region, occurring at a depth of 50km, and triggered tsunami warnings that have since been lifted.
- Thousands of homes were left without power, and train services were suspended; authorities warn of potential aftershocks in the coming days.
- No irregularities were reported at nearby nuclear power plants, including the Fukushima site, which was severely damaged in the 2011 earthquake.
- Japan, located on the Ring of Fire, experiences frequent seismic activity, with experts predicting a high probability of a megaquake in the Nankai Trough within 30 years.
A powerful magnitude 7.5 earthquake rattled north-eastern Japan on Monday night, injuring at least 30 people and forcing the evacuation of approximately 90,000 residents. The tremor, which struck at 23:15 local time (14:15 GMT), had its epicenter 80km off the coast of the Aomori region at a depth of 50km, according to the Japan Meteorological Agency.
Immediate Impact and Response
The quake triggered tsunami warnings, with waves reaching up to 70cm observed at several ports, including Kuji in Iwate prefecture. Although these warnings have since been downgraded, the initial alerts prompted widespread evacuations. The fire and disaster management agency reported that most injuries were caused by falling objects, with one individual sustaining serious injuries. In Hachinohe, a high school vice-principal described scenes of chaos as residents attempted to flee, leading to traffic jams and accidents.
Infrastructure and Power Disruptions
The earthquake left thousands of homes without power, particularly in the Aomori prefecture, and led to the suspension of train services along the north-eastern coast. East Japan Railway halted operations in the affected areas, while about 200 passengers were stranded overnight at New Chitose Airport in Hokkaido.
Nuclear Safety and Historical Context
In the aftermath, Tohoku Electric Power confirmed no irregularities at its Higashidori and Onagawa nuclear power plants, and the Fukushima site also reported no issues. This reassurance comes in light of the devastating 2011 earthquake and tsunami that severely damaged the Fukushima nuclear facility. Japan, situated on the seismically active Ring of Fire, experiences frequent earthquakes, with experts warning of a potential megaquake in the Nankai Trough in the coming decades.
Government and Public Preparedness
Prime Minister Sanae Takaichi urged residents to review their earthquake preparedness plans, emphasizing the importance of securing furniture and being ready to evacuate. The government has established a response office within the prime minister's crisis management center to coordinate relief efforts. Chief Cabinet Secretary Minoru Kihara stated, "We are making every effort to assess the damage and implement emergency disaster response measures."
WHAT THIS MIGHT MEAN
As Japan grapples with the immediate aftermath of this earthquake, attention turns to the potential for aftershocks and the ongoing risk of a larger seismic event. The government's swift response highlights the country's preparedness for such natural disasters, yet the threat of a megaquake in the Nankai Trough looms large. Experts continue to stress the importance of public readiness and infrastructure resilience in mitigating future risks. The situation also underscores the critical need for ongoing monitoring and safety measures at nuclear facilities, given Japan's history with seismic activity and nuclear safety concerns.
