They are nothing to do with tides.
Tsunami means harbor wave which is a good description - at sea they are almost unnoticeable - it'sonly when the water is concentrated on a shore - or in a harbor that they have such an effect
- rubashov 16y agoNot really getting the "harbor" connection. And it still looks like a big surge tide rolling in.
- chc 16y agoIt's because the tsunami only becomes visible when it hits your harbors. They used to be called "tidal waves," but the term is inaccurate — that's why it isn't used anymore. They're not like normal waves out at sea, and they have nothing to do with the tides. The fact that it "looks like a big surge side rolling" in does not actually make it tidal.
- jarek 16y agoIt only becomes a visible problem in harbours (or otherwise in shallow waters). It looks like a tidal wave in the sense that it's a lot of water moving in a given direction. The mechanism causing it is not the same at all, so the name tidal wave is misleading.
- mixmax 16y agoAs an example a friend of mine was on a boat during the massive 2004 tsunami, but since he was a few miles off the coast where the water was deep he didn't even notice the tsunami sweeping under his boat. Once it hit land it did massive damage.
- khafra 16y agoI think Rubashov understands that the process generating these waves is nothing like that which generates the tides, but correctly observes that the process resembles a tide--huge volumes of water rising, then falling back into the sea--more closely than ordinary waves, no matter their size.
