A strong earthquake with a preliminary magnitude of 7.0 struck under the
sea several hundred miles (kilometres) south of Japan on Sunday,
shaking buildings in the capital, but officials said there was no danger
of a tsunami.
The quake struck near the uninhabited island of
Torishima in the Pacific Ocean, about 600 kilometres (370 miles) south
of Tokyo, and its epicentre was about 370 kilometres (230 miles) below
the sea, the Meterological Agency said.
