Disaster-weary Japan has been rattled by another strong quake, which measured at a preliminary magnitude of 6.8, triggered a tsunami warning and sent people diving for cover.

The Friday quake struck the Pacific seabed not far from the epicentre of the March 11 quake-tsunami disaster that killed more than 20,000 people and triggered the world's worst nuclear crisis since Chernobyl 25 years ago.

Sirens again wailed along the devastated northeast coast, where people have been terrified by hundreds of aftershocks over the past five months, and the quake also caused buildings to sway across Tokyo.
