Earthquake-proofing a dam
Kansas is better known for tornadoes than earthquakes, but that doesn’t mean they don’t happen here. In fact the federal government is willing to bet millions that one will.
Bracing for the big one
As shown by the tremors that hit the Midwest just weeks ago, earthquakes in the U.S. aren't just restricted to the West Coast. Their potential to strike in this region has the federal government undertaking a massive construction project to protect one of the state's major dams.
An engineering feat
It's a project unlike any other in the world. The U.S. Army Corps of Engineers is stabilizing the ground beneath Tuttle Creek dam to brace it for a 6.6 earthquake. Take a look at the work that is going on.
At the base of Tuttle Creek Reservoir, a 20-ton clamshell excavator removes giant buckets of earth, making way for huge concrete walls. The amount of cement in those walls could pave a sidewalk between Tuttle Creek just outside Manhattan, Kan., and Washington, D.C.
