The Financial wisdom of having mom, dad, and grandma living in the same place.

I'm David Brancaccio in New York. At least nine people have died in Taiwan after the 7.4 magnitude earthquake hit during the Wednesday morning rush hour.

The big one was followed by many aftershocks, including at least two intense ones.

Taiwan is a major producer of advanced semiconductor chips for the world.

Marketplace's Nova Safo has more.

Taiwan Semiconductor Manufacturing Corporation said it evacuated some of its fabrication plants on the island

after the earthquake struck, but some employees have begun

returning to work. The company said its safety systems were operating.

T.S.M.C. is the world's biggest semiconductor chip manufacturer.

It supplies companies such as Apple and NVIDIA, which is having a moment

thanks to an artificial intelligence boom.

Taiwan manufactures nearly all of the world's most advanced chips, and the production of such

chips is highly sensitive. Vibrations and shutdowns could lead to major setbacks.

While the country has strong building codes, there were some images of serious damage coming out of the island.

And that again puts focus on the concentration of advanced chip production in Taiwan and in South Korea.

That concentration became a weak link in the global supply chain during the

COVID pandemic.

Two years ago, Washington enacted the $50 billion chips and science act to increase

advanced chip production in the U.S.

Something that's taking longer than previously anticipated.

And we continue to track an outbreak of bird flu in Texas, the largest egg producer in the U.S.
