TOKYO, Jan 6: A 6.2-magnitude earthquake jolted Japan’s Shimane and Tottori prefectures on Tuesday morning, the Japan Meteorological Agency (JMA) reported. No tsunami warning has been issued, authorities said.
The initial tremor struck eastern Shimane Prefecture at 10:18 a.m. local time, registering an upper 5 on Japan’s 7-point seismic intensity scale. It originated at a depth of 10 kilometres. Two additional quakes followed: a 5.1-magnitude tremor at 10:28 a.m. and a 5.4-magnitude tremor at 10:37 a.m., measuring lower 5 and 4 on the seismic scale, respectively.
Officials confirmed that no abnormalities were detected at the Shimane nuclear power plant in Matsue following the earthquake.
Disruptions to transport
The Sanyo Shinkansen Line services were temporarily halted between Okayama and Hiroshima due to a power outage caused by the initial quake. JR West reported that services are expected to resume by around 1 p.m., while other sections of the line experienced delays.
No casualties reported
There have been no reports of injuries, and local authorities are monitoring the situation for any aftershocks or potential impacts on infrastructure.
Recent seismic activity in Japan
This follows an earlier quake on December 31, 2025, when a 5.7-magnitude earthquake struck off Iwate Prefecture in northern Japan. The tremor, at a depth of 30 kilometres, registered 4 on Japan’s seismic scale in Morioka City.
