A tsunami warning has been issued after an earthquake with a preliminary magnitude of 6.8 struck off the coast of Northern Japan. The quake hit Thursday morning just before 7 a.m. local time near the east coast of Honshu, Japan, about 328 miles from Tokyo, according to the U.S. Geological survey. The quake was followed shortly after by a magnitude 6.7 tremor.

The Japan Meteorological Agency warned that the quake could generate a tsunami of about one-half meter. The Pacific Tsunami Warning Center has not issued any warnings or watches for the area, however.

So far, there have been no reports of injuries or damages.

The earthquake was in the same area of the Pacific where a magnitude 9.0 earthquake struck northern Japan on March 11, triggering a deadly and destructive tsunami.
