A magnitude 6.1 earthquake struck off Chiba Prefecture, Japan, at about 7:39 p.m. local time on the 6th. According to the Kyunghyang Shinmun, no tsunami warning was issued, and South Korea's weather agency said the quake had no impact on the country.
Citing the Korea Meteorological Administration, the Kyunghyang Shinmun reported that the quake occurred around 7:39 p.m. on the 6th, roughly 202 km east-southeast of Chiba city. The epicenter was near 35.0 degrees north and 142.2 degrees east, and the focal depth was put at 10 km. The time, magnitude, location and depth were drawn from the Japan Meteorological Agency's analysis.
광고 문의 · 300×250AFP, citing the Japan Meteorological Agency, said the quake struck at a relatively shallow depth offshore in the Kanto region near Tokyo. The Kyunghyang Shinmun said the Japanese agency announced the quake based on data from foreign observation bodies, among others. The same report confirms that no tsunami warning was issued.
However, whether the quake caused casualties or property damage, and the seismic intensity recorded in each part of Japan, had not been confirmed in the reports available. We will report only confirmed details as local authorities release more information. Figures such as magnitude and depth may be revised over time.
An offshore epicenter about 200 km from Tokyo
That the epicenter lay more than 200 km from Chiba city, out at sea, is one clue to how much the land may have been affected. Still, a magnitude 6.1 is no minor event, and the status of Tokyo-area rail service and industrial facility inspections must await local announcements. No confirmed reporting on this exists yet.
Japan sits on the Pacific Ring of Fire, and quakes of around magnitude 6 are not rare there. Whether this quake is linked to an earlier one, and how likely aftershocks are, can only be judged after the agency issues follow-up explanations. Readers living in or planning to visit Japan are advised to check official notices from the local weather agency and municipalities.
