On Monday evening, a strong earthquake struck off the coast of eastern Taiwan, the Central Weather Bureau said, shaking felt in the capital Taipei but no immediate reports of damage.
The epicentre was given in the sea 56 kilometres east of the coastal city of Hualien.
The weather bureau said the quake measured 6.0 in magnitude and hit at the relatively shallow depth of 19 kilometers. The United States Geological Survey put the magnitude higher at 6.2.
The weather bureau said no immediate reports of damage had come in.
Taiwan is regularly hit by earthquakes as the island lies near the junction of two tectonic plates.
Some earthquakes of this magnitude can prove deadly, although much depends on where the quake strikes and at what depth.
A 6.5-magnitude quake struck northeastern Yilan in October with minimal damage, in part because it was at a depth of 67 kilometres.
Hualien, a tourist hotspot, was struck by a 6.4-magnitude earthquake in 2018 that killed 17 people and injured nearly 300.
