An earthquake with a preliminary magnitude of 6.9 jolted Tokyo and wide areas of eastern Japan on Sunday evening, the Meteorological Agency said.

There were no immediate reports of injuries or damage from the 7:56 p.m. quake that originated some 340 km under the surface of the sea off the Tokaido area and lasted an unusually long time, the agency said.

There was no fear of tsunami following the earthquake, it said.

The temblor measured 4 on the Japanese seismic scale of 7 in central Tokyo as well as several parts of Miyagi, Fukushima, Ibaraki, Tochigi, Saitama and Chiba prefectures.
