AFPTOKYO — Two strong earthquakes jolted the ocean floor off southern Japan on Monday, triggering tsunami warnings for a cluster of sub-tropical islands and shaking buildings in nearby Taiwan.
There were no immediate reports of casualties or damage.
A 6.7-magnitude quake struck in the morning southwest of Ishigaki-jima island in Japan's far southern Ryukyu Islands, followed by a 6.4-strength tremor in the evening, the US Geological Survey reported.
Japan's meteorological agency issued and lifted tsunami alerts both times for a group of islands in the East China Sea.
The quakes could be felt in Taipei but caused no damage.
The first quake struck at around 9:06 am (0006 GMT) some 115 kilometers (70 miles) southwest of Ishigaki-jima, and the second at 7:11 pm (1011 GMT) 140 kilometres southwest of the island.
