A map with "live" simulated wavefront?

I guess this isn't possible, at least by our side. I don't think Wikimedia has such... software infrastructure like to generate that, or broadcast that either.
The original person is likely recalling the wavefront GIF produced for the last really big tsunami.
It'd be an idea to look on Commons to see who produced that. Might be available by the time we're doing a followup article.
