"The earthquake that shook the East Coast last week rattled casks holding radioactive nuclear waste at a Virginia plant, moving them as much as 4.5 inches from their original position, the plant's operator said.

The 5.8-magnitude quake shifted 25 casks, each 16 feet tall and weighing 115 tons, on a concrete pad at Dominion Resources Inc's North Anna nuclear plant."
