Overview
- JMA logged a magnitude 6.7 quake at 11:44 a.m. local time off Aomori at roughly 20 km depth, with shindo 4 shaking in parts of Hokkaido, Aomori, Iwate, Miyagi and Akita.
- Small tsunami waves of about 20 cm were observed in Hokkaido and Aomori, and the advisory for Hokkaido–Aomori–Iwate–Miyagi was lifted after roughly two hours.
- No significant damage was reported from Friday’s tremor, and regulators said no abnormalities were detected at the Higashidori, Onagawa or Fukushima nuclear facilities.
- The latest jolt follows Monday’s M7.5 offshore quake that caused a small tsunami, injured dozens and disrupted transport, including suspended rail services and flight cancellations in Hokkaido.
- Authorities urge coastal communities to stay prepared under the JMA’s ‘subsequent earthquake’ advisory, which signals an elevated but low-probability chance of another large shock over the next week.
