There is an awesome article how engineers are retrofitting UC Berkley’s stadium. Why?

Memorial Stadium was built in 1923 atop the Hayward Fault, which the U.S. Geological Survey said has a 70 percent chance of hatching a 6.7-magnitude or greater quake by 2030. The earth could move up to 6 feet horizontally and 2 feet vertically, presenting a challenge to engineers charged with saving the stadium and the football fans who might be inside.

While plenty of buildings around the world sit atop earthquake faults, Memorial Stadium is unique because of the sheer quantity of people it holds: 75,662. It’s also unique because seismologists know exactly where the fault lies – under Section LL, through both end zones and out Section XX.

Cool.
