"...Moved the entire island of Sumatra about 100 feet..."

You've probably heard by now about the 9.0 magnitude earthquake that struck in the Indian Ocean yesterday, the strongest quake on the planet in 40 years, and the fourth-largest quake ever. Massive tidal waves struck coastal areas from India and Sri Lanka to Indonesia. Right now they're saying over 12,000 people dead, and some entire coastal villages washed out to sea.

Here's what gets me, though. Drudge is reporting that the quake "...moved the entire island of Sumatra about 100 feet toward the southwest." An entire island, over 470,000 square kilometers, moves 100 feet. Wow...
