"Why are they claiming that the tsunami on the east coast of North America will be 100+ feet high, while at the UK, which is nearer, it will be only a tenth that?"

I am not certain myself but it may have to do with the topography of the ocean floor. in between La Palma and England, just off the west coast of Spain are a lot of seamounts that are nearly islands that could dissipate the wave energy.
