"If you have a degree you can make any crazy claims you like."
This is not a crazy claim, it was documented in a television program on one of the cable channels. It is a hugh amount of earth that will eventually slide into the sea. This is the equivalent of you slipping into the bathtub. It sends a wall of water in the opposite direction. It is not really a matter of if, more a matter of when. The island earth mass is honeycombed with collected water which is leading to the certain slip into the sea.
Are you series?
This is the equivalent of you slipping into the bathtub.
Given the size of the Canary Islands and the size of the Atlantic Ocean, it's more like me dropping my keys in the bathtub. Probably less in terms of the ratio of land mass vs. the amount of water.
I just don't buy the proportions here - this much rock vs. the Atlantic does not equal all that much displacement, proportionally. I know it would cause a massive disturbance, but I don't see how it would propagate a 300 foot tall wave 3000 miles away.
