TSMC expects to resume production overnight after a 7.4 magnitude earthquake, Taiwan's biggest in 25 years, and says “there is no damage to our critical tools”

- Chipmakers move some staff off of unspecified operation areas — The earthquake rocked Taiwan and triggered tsunami warnings

Bloomberg 2024-04-03 Debby Wu

Context & Ripple Effects

The immediate issue is whether a major disruption at TSMC can turn into a broader supply interruption. The company said its critical tools were undamaged and expected production to resume overnight, even as chipmakers moved staff from unspecified operating areas.

Follow-up coverage characterized the response as evidence of Taiwan's chip-sector earthquake readiness, while TSMC later put the event's estimated loss at about $92.44 million without reported fab structural damage or power outages. That distinction matters: operational continuity can be preserved even when a disruption still carries a financial cost.

First-order effects

TSMC can focus on restarting production rather than repairing critical fabrication equipment, reducing the duration of the immediate operational interruption.
Staff relocations and safety checks remain the near-term constraint for affected chipmaking areas, despite the planned overnight restart.

Second-order effects

A rapid restart lowers the immediate risk that TSMC customers face a material supply interruption, though the incident can still generate recovery and loss costs.
The event reinforces the value of tested fab-continuity procedures; related coverage also points to similar preparedness in Japan's chip industry, raising the bar for resilience planning across regional production hubs.

Third-order effects

If fast recovery becomes the norm, semiconductor resilience will be judged less by whether disruptions occur than by whether fabs can protect tools and restore output quickly.
The remaining structural exposure is concentration: a localized event can still force global customers to assess how much production risk they accept in a single manufacturing region.

The trend: This is one data point in the semiconductor industry's shift from treating continuity planning as a back-office safeguard to treating it as a core capacity advantage.

2/5 TSMC and the Taiwan semiconductor industry recovery time from this earthquake may be a few days, perhaps a week, barring major incident. It takes time to check for structural damage, make sure there are no gas or other chemical leaks, recalibrate production line equipment,...

#TSMC said Wednesday morning that, judging by the current situation, the strong earthquake in #Taiwan is expected to disrupt the operation of some of its factories for less than six hours, which will have an impact on TSMC's second-quarter earnings forecast of about $60 million.

Taiwan was struck by its strongest earthquake in 25 years few minutes ago when a 7.4 magnitude tremor struck the island's eastern coast, prompting tsunami warnings across the region. A rooftop swimming pool during the Taiwan earthquake. [video]

TSMC took no damage from a magnitude 6.4 quake (its epicenter close to the fabs), except losing some half-baked wafers. Today's 7+ quake near Hualien County might not affect chipmaking at all. Tbh, after witnessing 2023 Turkey-Syria catastrophe I feel even more respect for TW&JP …

the footage shows the evacuation of the staff of TSMC - the largest chip manufacturer in Taiwan, due to an earthquake off the east coast of the island, this is one of the many reasons why I wish people had more than one TSMC [video]

how does a tsmc fab with absolute precision requirements survive an earthquake, i wonder

Latest on Taiwan earthquake: - at least 7 people dead, 736 injured - 77 people have been trapped - aftershocks expected in the coming weeks - TSMC is still assessing the impact

Taiwan's 7.2-magnitude earthquake and 6.5-magnitude aftershock caused TSMC and UMC to evacuate staff from some fabs in the Hsinchu and Southern Taiwan Science Parks, media report, adding UMC said some machines shut down, yet all staff are safe and are now assessing the situation.…

So TSMC's fab is pretty earthquake proof. That being said, it's a good moment to appreciate just how sensitive these processes are. any fab shutdown/disruption causes hysteresis and the need to recalibrate machinery, which can take weeks.

IMO biggest risk is not to $TSM but their clients. TSMC has such big marketshare that any disruption will increase demand for it's product, like Intel Spectre & Meltdown vulnerabilities in 2018 actually increased sales due to the performance hit of fixes https://twitter.com/...

$MU Micron is evaluating its operations and supply chain after the earthquake, the company said. Micron is the largest foreign investor in Taiwan. Its output accounts for about 60% of the company's overall DRAM capacity. Source: Bloomberg

TSMC: A number of machines will need to be temporarily shut down for inspections. It is estimated that the work will be affected for less than 6 hours, and the impact on the Group's 2FQ is forecasted at about US$60 million, with limited impact overall. #Taiwan #Earthquake

I appreciate the many messages, but I — and nearly everyone else in Taiwan — am fine. Taiwan was hit by a 7.3 earthquake in the center of the island in 1999. It was a massive tragedy. However, everything built since then — and everything that survived — is very safe. My...

what effects the taiwan earthquake may have on GPU supply: • the 7.7 taiwan earthquake in 1999 was 68mi from some fabs; UMC lost 10% of production and TSMC was back up to 85% capacity after just one week • even so, spot prices on memory went up 50% YoY and many other... [image]

The 7.4 #earthquake in #Taiwan at 7:58 local time (23:58 UTC) briefly disrupted Internet traffic, dropping it by ~5%. Within an hour, traffic surged to 5% above normal. Mobile networks were the most affected: Emome (AS17421) saw a 24% drop, Taiwan Mobile (AS24158) 19%. [image]
