TAIPEI, July 28 (Reuters) – Taiwan Semiconductor Manufacturing Co, the world’s largest contract chipmaker, ​said late on Tuesday ‌it had begun gradually resuming operations at its Japan Advanced Semiconductor Manufacturing (JASM) plant in Japan’s ‌Kumamoto ​prefecture after ⁠a strong earthquake ⁠prompted the precautionary evacuation of workers.

A 7.1-magnitude earthquake hit the prefecture earlier on Tuesday.

The ​company said all personnel at the Japan site ⁠were confirmed safe ⁠after being evacuated ​in accordance with internal safety ​procedures.

“Post-earthquake structural inspections have been ‌completed, confirming that the structures are safe and operations are gradually resuming. Detailed ⁠inspections and impact assessments are ongoing,” it said in an emailed statement.

JASM’s ⁠construction ‌site was unaffected, ⁠TSMC said, adding that ​parts ‌of the construction ​work had ⁠been suspended as a safety precaution because there could still be occasional aftershocks.
