On Wednesday at around 7:58 am local time, a 7.4 magnitude earthquake struck off of Taiwan's east coast, with the epicenter 18km from Hualien City. The country issued Tsunami warnings while Japan and the Philippines also braced for possible flooding. According to the U.S. Geological Survey, this is the most powerful quake Taiwan has experienced since a 7.7 event that occurred in 1999. The USGS also says that a 6.5 aftershock occurred 13 minutes later.
At around 9 am local time, Bloomberg reported that TSMC, one of the world's largest chipmakers, had evacuated some plants as a precautionary measure. Wen-Yee Lee, a semiconductor reporter in Taiwan, tweeted an update from TSMC stating that some facilities had been evacuated as part of "internal company protocols."
The good news is that TSMC's foundries are located on the west side of Taiwan, while the quake occurred off of the east coast. The Financial Times has a great map showing the location of TSMC's 12 Taiwan fabs, which are spread out between Tainan, Taichung, Hsinchu City, and Taoyuan City. According to Asia Tech Wire, the chip giant stated that it estimates a 6-hour disruption in production.
According to CNN, as of 11 am Taiwan time, there were at least 26 building collapses with at least 15 of the buildings in Hualien County. More than 91,000 households were without power. Videos posted on Reddit show significant shaking in Taipei, with Taipei 101, one of the world's tallest skyscrapers, shaking.
Aside from the human cost, this quake could also significantly affect chip production, potentially causing shortages or raising the prices of key components. This would, in turn, lead to higher costs for everything from laptops to TV sets.
TSMC is not the only company that manufactures major components in Taiwan, however. According to Bloomberg, UMC (United Microelectronics Corporation) has also evacuated its fabs. These are also located on the west side of the island, which means that they were likely not hit by the quake.
It's important to note that even short disruptions in production can lead to big price hikes, and Taiwanese earthquakes have a long history of disrupting the global electronics supply chain. After the 1999 quake, prices for DRAM modules jumped by more than 25 percent, and shortages continued for months.
We'll have to see what the effect of this latest disruption is on the prices of key PC components such as CPUs and DRAM.
Jobs eviscerated at Chinese Arm chip design firm in wake of restrictions from TSMC — lack of access to 7nm node could cause 150 employees to be laid off
Chinese chip firms say a new round of US sanctions won’t stop China’s chip industry — Chinese government responds with its own export restrictions anyways
