In brief
A 5.7‑magnitude shock jolted central Japan on Sunday morning, leaving more than 20 people wounded in Aichi and Shizuoka prefectures. The tremor, occurring at about 40 kilometers depth, generated an upper‑5 seismic intensity in Chita City and prompted temporary suspension of local trains and delays on the Tokaido Shinkansen line. The central government assembled a liaison office to coordinate the response while the Hamaoka Nuclear Power Plant reported no abnormalities.
Tokyo, Nov. 8 — An earthquake of preliminary 5.7 magnitude struck central Japan early Sunday morning, injuring more than 20 people across Aichi and Shizuoka prefectures and prompting temporary rail suspensions and federal coordination. The tremor, reported by Kyodo News and confirmed by the Japan Meteorological Agency (JMA), struck at approximately 1:04 a.m. local time in western Shizuoka Prefecture and had a depth of roughly 40 kilometers.
According to JMA data, the quake registered an upper‑5 level on Japan’s seven‑level seismic intensity scale in Chita City, Aichi Prefecture. This intensity level, a direct measure of ground shaking, led to observable damage in several locales and prompted rapid emergency responses.
The impact was felt most acutely by residents in Aichi and Shizuoka, with more than 20 injuries reported. Local medical facilities in the affected prefectures documented the injuries, and emergency services responded immediately to provide care and assess structural damage across the region.
Despite the pronounced shaking, no tsunami warning was issued. The Japan Meteorological Agency stated that seismic activity did not meet the threshold for tsunami generation, and coastal monitoring systems recorded no significant oceanic response.
The Hamaoka Nuclear Power Plant, located in Shizuoka Prefecture, reported no abnormalities. Chubu Electric Power Co., the plant’s operator, confirmed on the day of the quake that all safety systems remained functional and that the plant continued to operate within normal parameters.
Rail operators, however, faced disruptions in the wake of the event. Several local train services were suspended as crews inspected infrastructure for damage. Additionally, the Tokaido Shinkansen‑bullet train line experienced delays between Shizuoka and Gifu‑Hashima stations while safety checks were conducted to ensure passenger security on the high‑speed corridor.
In response to the quake, the central government convened a liaison office to coordinate the overall response. The liaison office, established for the purpose of synchronizing efforts between emergency services, transport authorities, and utility companies, is expected to oversee the ongoing assessment of damage and the restoration of services.
Both national and local agencies are closely monitoring the situation, with JMA continuing to publish updates on seismic activity. In the days following the quake, authorities will likely conduct further inspections of critical infrastructure, including bridges and tunnels, to confirm the safety of transport and utility networks.
Early passenger advisories recommend that travelers avoid travel to affected areas until local authorities declare it safe. Meanwhile, emergency responders remain on alert for any potential aftershocks, which are common following seismic events of this magnitude in the region.
Although no immediate aftershocks of notable size have been reported, officials emphasize that the area remains under observation. The coordinated approach of the liaison office aims to ensure rapid, informed actions as new information emerges from local monitoring stations and field assessments.
