Yeah, you have to wonder if tourists in Maine or Nova Scotia are going to wig this summer if they're on the shore and see the tide screaming out 15 feet or something.
Even leaving aside my weird obsession with the physical sciences and tsunami documentaries from well before the Sumatran tsunami, because I do a lot of saltwater fishing I'd notice an unusual tide, and also since I have a saltwater reef tank I'd know that those coral heads aren't typically TOTALLY exposed to that extent.
wonder how Nova Scotia would know...
They have the highest tides on earth... 15 feet and 14 billion tons of water come in on them twice a day
