@@sxphiii_ A tsunami can be caused by a number of things i. e water displacement by a landslide as in Krakatoa, or an earthquake, or, in this case, a ship. The principles are the same - as I said, it's obviously on a small scale but the wave behaves the same.
@@amandaprice3395 yes I understand but tsunamis are caused by earthquakes under the ocean. They usually happen to a country on the border of a tectonic plate. If you search on Google, ' map with tectonic plates' you can see that ireland is no where near a tectonic border.
@@sxphiii_ I know that I'm from Ireland. You obviously don't understand a word I said. Yes it CAN be caused by an earthquake but it can also be caused by OTHER methods of water displacrment.
Awesome. I just subscribed to your channel. Keep ‘em coming. Nice to see different scenery. That’s weird how it’s pulling the water down in front of the ship. Most of the tankers that pass through our area push water at the front.
How interesting - I saw the same thing about 5 years ago - it was winter evening and nearly dark and the car ferry approaching the lighthouse - and it was as though the bow wave separated and moved forward just as in your clip - thank you for posting and saving my sanity as I thought afterwards had I imagined it
Tsunami is a term for earthquake caused waves. A ship's wake is not a tsunami. You got over 100,000 views on this so well done there. How does that happen?
@@Straya09 No, technically it is not, you are misusing the term. The on-line Oxford dictionary defines tsunami as a long, high sea wave caused by an earthquake, submarine landslide, or other disturbance; Wikipedia defines it as a wave or series of waves in a water body caused by the displacement of a large volume of water, generally in an ocean or large lake; earthquakes, volcanic eruptions and large explosions have the potential to generate a tsunami. In both these definitions, the emphasis is on large - large wave, displacement of a large volume of water. A "small tsunami" is an oxymoron. The Oxford dictionary of Earth Sciences gives an even more precise definition: A seismic sea wave of long period, produced by a submarine earthquake, underwater volcanic explosion, or massive gravity slide of sea bed sediment. Again, the emphasis is on massive.
I was sitting at the beach what is this possibly true because a cargo ship was passing by and a wave just hit me and dragged out my family The wave was 10 times larger because I was in a tropical storm.
Is that true?.I believe it was a natural phenomena occur on a certain period of time . The main reason are because of the seasonal changes approaching the summer or the North iceland melted the ice.
That is an insult to all the tens of thousands of people who died in the Indian Ocean Tsunami in 2004 ! What you see here is a simple wave caused by an ocean liner.
Not really though - this is a weird phenomenon that I too experienced once and am glad that someone else caught it on camera - the poster does explain how the water is drawn out and then comes back in so fast and says that this clip shows how dangerous a tsunami can be....
And I come from Ireland I mean northern Ireland and I do know that we do get severe weather Here the last one was a category 2 hurricane ophelia and category 1 hurricane brian #opheila
Sarah - Jayne Mullan would you not be better saying you come from the north of Ireland as when you say you come from Northern Ireland its kind of saying you are adhered to the British policy of dividing
Interesting, the lighthouse on the south shore is red, and the north shore is green. To me this is "backwards" - is this backwards? I expected the red on the right as ships return to port.
Wow this tsunami must have taken down a lot of big buildings! Not!!..... It was caused by the ships wake. A tsunami wave height usually starts at about 20 ft. on up to possibly a hundred feet. And the width of them can be miles.
Not a tsunami. Not a rip tide. Not a tidal wave or tidal bore either, but if one didn't know about the ship, those actually wouldn't be bad guesses. It is of course, the bow wave of a ship. [EDIT: I've a suspicion that this might actually be video of two ship-wakes stitched together.] At least two commenters drew attention to the way the wave was initially 'drawing back' in a counter-intuitive way, one of them specifically mentioning the similarity to actual tsunamis- possibly she's actually 'onto something' in this, but that's physics at well above MY pay grade, so to speak. Basically though, it's just the way the ship's 'bulbous bow', which is there to give the ship hydrodynamic efficiency, is literally making the water 'get out of the way'. Possibly also something to do with the ship slowing down as it enters the harbour- in part to mitigate the bow-wave. Incidentally, I laughed along with everyone else at the ignorant- if not out-and-out clickbaity title; nonetheless, these ship-wakes are potentially dangerous for people on the shoreline (especially in otherwise placid waters). So much so that the municipal authorities in Dublin have had to erect signs warning people of the danger. These waves can be considerably higher than people give them credit for, and also, sneakier. Incidentally, I am not an expert in hydrodynamics, oceanography or piloting ships; merely an interested 'amateur'
@@romanomorelli2831 Thank You... and yes, the conditions you describe would be applicable in Dublin Bay (in fact one would even be able to infer as much from an ordinary map.) I have to admit though, it hadn't occurred to me 'til you mentioned it.
looks like a spring tide to me.. (yes spring tide, not rip tide. a rip tide is the backflow current of water pushed on shore by regular waves. google it.) and by the way i'm not a scientist who has to mention in the description 'by the way i am a scientist' to impress whichever poor sod may be easily impressed by people's credential-less words on social media. i'm merely a person who enjoys science and hence reads/watches a lot of books and documentaries by credible sientists.
not a tsunami.....for some reason people seem to keep labeling wind blown, tidally influenced, and ships. wake Tsunamis on youtube, many of these wouldn't have been survivable for the camera operator if it were indeed a tsunami...So, for their sake i am glad they are wrong.....hopefully these operators will not learn the hard way what the difference is
J. C B Tsunami waves are.nothing more than displacement of water.Tsunami waves can be made by landslides both from rockfalls above water and large landslides under water ,undersea earthquakes,volcanoes,and large ships that displaces the water around them,draging after them self the wave of water.Tsunami waves from ships though are smaller than the big scale natural made Tsunamis,but behave and act just like theyr adult cousins which is water set in motion.The ship Tsunami waves can be quite dangerous and they are destructive and have killed and drowned people strolling along the shorelines,suddenly being swept away by the strong currents and force of the water.
MashUp Beatz rip tides and currents are completely different.that is made by undercurrents and normal waves.This is a ship tsunami made by the displacement of water that the ship is displacing and drags after it self. Can be quite dangerous ,being caught on the shore by these and they are quite destructive too.It depends on the size and speed of the ship ,and how and where it occur.
