Earlier today, TSMC evacuated some of its fabs in Taiwan after an earthquake and is evaluating the loss of production.

“TSMC’s safety systems are operating normally,” says the company, “to ensure the safety of personnel, some fabs were evacuated according to company procedure. We are currently confirming the details of the impact.”

TSMC said construction sites were normal upon initial inspection, but the company decided to suspend work at the sites for the day.

Staff evacuated from some plants have started to return to work.

The earthquake measured 7.4 on the Richter Scale – the worst quake Taiwan has suffered for 25 years.
