Yeah but I dont remember too many tsunamis when i was growing up.
Look no further than:
MOTHRA!!!!!
If you're older than 50, then, when you were young, there were only 3 networks , and they only had news broadcasts in the evening. There was little coverage of international events that didn't affect us.
Nowadays, there are those same 3 networks, but several others that accommodate "Breaking News" on a 24/7 basis. They'll flog a story for hours, even if there is no real NEW information to be had.
There have always been tsunamis, we just never heard about them until recently.
They were called “tidal waves”. I didn’t hear the word “tsunamis” until I saw it on the transom of a yacht and was told it was named after a tidal wave.
