  That's an interesting one, from the comment above yours linked article The Tugunska event of 1908 instead had 50-60m, but caused only three deaths because it was over a sparsely populated area; it still affected 2.1K km2 (or about two NYCs worth). which raises questions about what kind of wave such an impact could create and what are the odds of that hitting a populated coastal town (or three) might be.
