A magnitude 6.1 earthquake was reported off eastern Japan on 6 November, with separate reports indicating delays to Shinkansen services near Tokyo.
The quake was reported at about 10:39 UTC (7:39pm Japan time). PTI News, citing the US Geological Survey, said it struck south-east of Hasaki. WION reported a magnitude of 6.1 near Tokyo, attributing its information to Japan’s Meteorological Agency.
Early estimates were not uniform: posts gave magnitudes ranging from 6.0 to 6.2, and described the location variously as off eastern Japan, off the Kanto coast or south-east of Hasaki. One post put the depth at 10 kilometres, but the supplied reports do not establish a final official estimate.
VolcanoDiscovery’s initial report, published at 11:00 UTC, described unverified ground shaking near Yokohama at approximately 10:39 UTC. It said the location and other details were provisional pending more precise seismic data; it did not independently confirm the magnitude.
Separate reports flagged Shinkansen delays near Tokyo, but the information supplied did not identify affected services or give an operator update. No reliable casualty or damage figures were available in the reports reviewed, and the tsunami situation was not independently established.
