MOSCOW (Sputnik) – The quake hit at 03:17 GMT on Thursday, about 60 kilometers (37 miles) southeast of Taiwan’s capital Taipei, USGS said.
The epicenter of the earthquake was located at a depth of 10 kilometers (6.2 miles).
There were no immediate reports of damages or casualties.
Taiwan lies along the so-called Ring of Fire, a horseshoe-shaped string of volcanoes around the Pacific Rim, where about 90 percent of the world's earthquakes occur.
In February, over 100 people were killed when a 6.7-magnitude earthquake caused a 16-storey residential building to collapse in Tainan.
In 1999, the small island nation east of China was devastated by a 7.6-magnitude earthquake that killed some 2,700 people. A previous tremor in 1935 claimed around 3,300 lives.
