The giant rusty barrels of nuclear waste did a little dance in Virginia. They shifted as much as 11 cm.
This probably indicates a PGV of 40-60 cm/s on soft soil, since they invariably put these things on the worse foundation possible. Of course we'll never know what the plant actually experienced, but I'm sure it was around 5-10 cm/s.
It reminds me of an old decrepit nuclear plant near Toronto. They put the nuclear waste in rusty barrels, propped up on rusty stilts, on a swamp. Since we determined they would fall with any earthquake, we actually had to show that the barrels would hold. Would make a fine mess.
