Magnitude 5.7 earthquake hits near Tokyo
The US Geological Survey said the quake had hit at 16:23 local time (0723 GMT), with its epicentre 57 kilometres north-northeast of Maebashi and around 143 kilometres north-northwest of Tokyo.
A few minutes later a 4.7-magnitude aftershock was registered, The Daily Yomiuri reports.
"It shook vertically for about 10 seconds. Nothing fell from
shelves and window glass was not shattered. There was no report of
fire and we are preparing to patrol the city," Takayuki Fukuda,
spokesman for the Nikko city fire department in Tochigi prefecture
near epicenter told AFP.
The Japan Meteorological Agency had earlier put the magnitude at
6.2. The agency said the epicenter was about 10km deep. It
registered 5 in most parts of Tochigi, including Nikko, 4 in
Fukushima and Gunma prefectures, 3 in Saitama and 2 in Chiba and
Tokyo, where tall buildings swayed for upwards of half a minute
after the quake.
National broadcaster NHK said no abnormalities were detected at
nuclear power plants near the epicenter.
