A magnitude 6.8 earthquake hit between Japan's southernmost islands and the coast of Taiwan today, briefly prompting a tsunami warning, Japan's Meteorological Agency said.
The quake struck about 9 a.m. about 80 miles southwest of Ishigaki. The Japanese resort island is about 125 miles east of Taiwan. The quake struck at a depth of about six miles, the agency said.
Naoto Otake, a police official on Ishigaki, said there were no immediate reports of damage or casualties on the island, which has a population of 40,000.
