After watching this video – which was supposed to convince me that a landslide on the island of La Palma in the Canary Islands would trigger a mega-tsunami, I remain unconvinced.
This BBC documentary shows what happened in Lituya Bay, Alaska when a giant landslide triggered a 1500 foot high tsunami – almost half a kilometer high!
Then it tries to interpolate what would happen if a similar landslide occurred on the Canary Islands.
“Scattered across the world’s oceans are a handful of rare geological time-bombs,” goes the story. “Once unleashed they create an extraordinary phenomenon, a gigantic tidal wave, far bigger than any normal tsunami, able to cross oceans and ravage countries on the other side of the world.
“Only recently have scientists realised the next episode is likely to begin at the Canary Islands, off North Africa, where a wall of water will one day be created which will race across the entire Atlantic ocean at the speed of a jet airliner to devastate the east coast of the United States. America will have been struck by a mega-tsunami.”
“Every city from New York to Miami, would be destroyed.”
As I said, I remain unconvinced.
Do I believe that flank of the volcano could collapse into the sea? Yes I do.
Do I think that would trigger a tsunami that would destroy the U. S. East Coast? No I don’t.
Think about it. Lituya Bay, Alaska, is a very small area in relation to the Atlantic Ocean. If I drop a rock into a 5-gallon bucket, I’ll generate a small “tsunami” that will wash over the rim of the bucket. If I drop that same rock into a swimming pool, no one will notice any change.
And if I throw it into the ocean?
New Yorkers, this is just one man’s opinion, but I don’t think you need to lose any sleep over this.
