By rough estimate, NY is about twice as far from the Canaries as London. Would London be destroyed in time to give NY lots of warning?

Yes and no. A smaller version of the tsunami would reach the UK first. The wave front, as I read it, gets greatly dissipated by the European Coast, the English Channel, the Thames Estuary, etc., so would not be as severe. Also I think the disintigrated flank of the volcano faces the East Coast of the US, so we would bear the full brunt of the mega-tsunami.
