I think the UK East coast is at greater risk than the west. There is a
geological record of tsunami's along the East coast which is, iirc,
particularly good along the Firth of Forth and Tay valleys.

I shouldn't have thought that the North Sea or the area to its north was
very geologically active, so I'm rather surprised. Are you sure that
these were true tsunamis rather than storm surges?
