TOKYO (AP) — A strong earthquake shook Tokyo early Saturday morning, knocking books from shelves, but authorities said there was no risk of a tsunami.
There were no immediate reports of damage or injuries.
The magnitude-5.2 earthquake was 57 kilometers (35 miles) deep and was centered in Tokyo Bay, near Haneda Airport, the Japan Meteorological Agency said. It struck at 5:49 a.m.
Subway and train service was briefly interrupted for safety checks.
The agency warned that the quake could cause landslides following recent heavy rains.
This story has been corrected to show the epicenter was in Tokyo Bay.
