When did everybody start calling a tidal wave a tsunami and why?

I had never heard of one until there was a programme on TV
around a year or so ago.

Weather bosses decided that it needed a more up to date image and
rebranding ............??



Could be they were looking for a short, snappy and memorable name for an
unusually large ocean wave caused by an undersea earthquake. The japanese
have a name for such waves, perhaps because they live on islands in an area
of frequent earthquake activity, so it probably made sense to adopt the
term.
