NOooo. I was not aware of this. Amazing, simply amazing. Before we came to America, Northwest had that huge quake (Alaska); and our mum told us about the "tsunami" which had sucked out to sea, a family who'd been camping on the beach (Crescent City). And, no joke, I could never relax and enjoy the waves on the west coast. Even camping on the beach north of SF, I swear I was awake all night long, wanting to be alert for the first hint of the water backdraw..... (Like I could have climbed up the huge cliffs and outrun any tsunami...)
The visual at the end of your urled article, makes quite the impression.
