"A big quake in the Canary Islands could create a tsunami which could hit the east coast of the USA."

Yup! If that thing went down bad enough, I would NOT want to be on the NC Outer banks! I doubt there would even be any islands left if a tsunami were to hit that place.

Based on a program I saw on the Discovery channel, roughly half of the islands land mass could slide into the sea. The resultant tsunami would come to the U.S. east coast.
