A powerful earthquake struck off the northeast coast of Japan on Friday, rattling buildings in Tokyo and setting off a small tsunami.

The 7.3-magnitude quake wasn’t as powerful as the 2011 quake and was further out to sea — 462 kilometers (287 miles) east-northeast of Tokyo at a depth of 36 kilometers (22 miles) — the U.S. Geological Survey said.
Some roads were closed and rail services suspended in the northeastern prefecture of Miyagi, where a one-meter (3-foot) tsunami rolled ashore. But there were no initial reports of damage or injuries, local police said.
Miyagi was one of the areas that suffered the worst of the destruction from the 9.0-magnitude quake and resulting tsunami in 2011.
