I assure you there is nothing ASB about this thread. What I'm about to post,
is within the realm of possibility. There's a volcano in the Canary Islands, the name escapes me at the moment, that last erupted in 1946. It's unusual because it has high water content in the lava. Its west side is about to collapse and slide into the sea. If it does, there'll be a tsunami. What if there
was an Atlantic tsunami? Without an early warning system like there is in the
Pacific, what would the effects be?
