Even large, damaging tornadoes have quite localized impacts (max of maybe a mile in path width) -- and you don't generally do much more than stay up to building code in order to prepare for one. In contrast, earthquakes devastate entire areas and require substantial changes to building construction in order to protect against them.

The probability of a large, damaging tornado at a particular spot in Ohio is quite small compared with the risk of damaging earthquakes in other locations. https://www.usgs.gov/faqs/what-probability-earthquake-will-o...

Tornado protection is mostly about avoiding damage in the periphery of a tornado. A building of that size can't realistically be protected from a direct hit of a major tornado. Proper engineering can protect a building from basically all earthquakes. Whether the contents inside are secured properly is a different matter and that's where most damage occurs.

Interesting. I'm unfamiliar with building code provisions that are designed to mitigate the effects of tornadoes, which are arguably the most destructive force on Earth apart from an erupting volcano or a nuclear attack, on a semiconductor fab, which is arguably among the most sensitive and easily-disrupted facilities ever built. Any good sources for further reading?
