Buildings shook briefly in Taipei on Monday as a 6 magnitude earthquake struck Taiwan's eastern coast, but there were no immediate reports of damage.
The quake had a depth of 6.8 km (4.2 miles) with its epicenter in Hualien county, a sparsely populated part of the island, the weather bureau said.
The quake could be felt across Taiwan, it said.
Taiwan lies near the junction of two tectonic plates and is prone to earthquakes.
