The quake with a depth of 73km was felt across Taiwan and shook buildings in the capital Taipei, the administration said, assigning it an intensity-four category, meaning there could be minor damage.

Taipei city’s government said there was no major damage reported in the immediate aftermath, with some isolated cases of damage, including gas and water leakage and minor damage to buildings.

More than 3,000 homes in Yilan briefly lost power, Taiwan Power Company said.

Major chipmaker TSMC said a small number of its facilities in the northern Hsinchu Science Park met evacuation thresholds after the quake, and evacuated staff had since returned to their posts.

The weather administration said people should be on alert for aftershocks between 5.5 and 6.0 in the coming days.

It also said damage from the quake should be limited because it was relatively deep and hit offshore.

Taiwan President Lai Ching-te said in a social media post that authorities had the situation under control and also urged the population to be on alert for aftershocks.

Taiwan lies near the junction of two tectonic plates and is prone to earthquakes.

More than 100 people were killed in a quake in southern Taiwan in 2016, while a 7.3 magnitude quake killed more than 2,000 people in 1999.
