A 7.0 magnitude earthquake struck some 32 km (20 miles) off Taiwan’s northeastern coastal city of Yilan on Saturday, the island’s weather administration said, with no immediate reports of major damage.

The quake with a depth of 73 km (45 miles) 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.
