TOKYO (AP) -- A 6.9-magnitude earthquake struck off Japan's southern coast Tuesday, shaking a broad swath of the country and swaying buildings in downtown Tokyo.
No damage or injuries were immediately reported, and Japan's meteorological agency said there was no danger of a tsunami.
The temblor hit at 12:25 p.m. local time (0325 GMT), with the epicenter near the Ogasawara islands, 500 miles (about 800 kilometers) south of the main Japanese island, the agency said. It struck at a depth of 300 miles (480 kilometers).
Japan is one of the most earthquake-prone countries in the world. In 1995, a quake of magnitude 7.2 killed 6,400 people in the western port city of Kobe.
