Ontario-geofish blog points out that at Yucca Mountain in the U.S., construction of a nuclear waste dump is being moved because a geological fault isn’t where the engineers thought it was. There’s a link to an article:
Bob Loux, head of the Nevada Agency for Nuclear Projects and the state’s chief anti-Yucca administrator, said he was not reassured by what he called “just-in-time engineering.”
“This represents a complete lack of understanding about the site’s characteristics,” Loux said. “They’ve been out there for 25 years or longer. And they get surprises like this. This is basic geology, stuff they should have known all along.”
There may be faults more or less everywhere, but it’s nice to keep track of them.
