‘Fly-Over’ States Critical
Much of the country’s inventory and resources are located in or travel through
the central US.
![Page 29: Central US Earthquake Risks & Their Distant Impacts](https://reader035.vdocument.in/reader035/viewer/2022062814/5681685d550346895dde986c/html5/thumbnails/29.jpg)
Much of the country’s inventory
and resources are exposed to earthquake hazards and
earthquake risks that are generally
unrecognized.
