Thank you, i never really understood how tsunamis happened because school's on picture study never got to me, but this is great. I shall know for ever.
That only happens when there is an accumulation of sediments along the fault lines. In the cartoon, there's no accumulation of sediments, so there won't be a pulling back of the water.
Not sure but i think for large water mass to suddenly rise and advance towards land, there has got to be some source of water to add to the normal volume. That extra amount is compensated by initial pulling back of shore water.
@@chere421 tsunami: caused my tectonic plates (or how they called sorry lol) and earthquakes mega tsunamis: it's true they're bigger, but they are mega tsunamis because something get's "added" like a meteorite or an iceberg falling inside the water (gon be more frequent bc of climate change"
Miller's Planet's waves are generated from Gargantua's tidal force. Since it will take a very long time before the planet will get swallowed up, it's almost certain that massive tide will never stop.
its not always like that, sometimes you have an quake and just a few min later you have water above your knees, it depends on strengt of the quake and how far and direction the waves has from land before created. The farther from land the wave tends to be longer and wider and sometimes much more dangerous, as they dont look as much before it floods in. take look at the 2004 tsunami or japan tsunami they dosnt look bad at all at first, but they are long and wide and keeps pushing in
the reason for that speed is an estimate of time they get from one wave to travel from one meassure point,to another.Usually they have bouyus in the pacific,that tells the scientists from the time the quake hit,to the waves is formed and is traveling in the oceanwater. in open water they move usually very fast. but as wider from the shockpoint the longer intervall of wave you have.sometimes they can take hours or days to hit land,other times just minutes
As it nears the shore it doesn't really resemble a real tsunami. It's more like a Hollywood version of a tsunami. Footage of the Asian tsunsmi shows that when it approaches land it becomes a choppy foamy mess, not a perfect wave
thanks, thats exactly that. What I dont understand is how they measure the tsunami wave in Japan as reaching 40 meters height, or the Indic Ocean tsunami reaching 30 meters high, if in absolutely NO VIDEO you see the tsunami covering buildings taller than 2 or 3 floors, nor any huge wave. Its like you said, a series of very short heighted rolling waves that keep coming with incredible force.
In case you’re still wondering after a decade. They are measured at sea level. Due to sea level being far below the land where a building is usually standing, the waves will never look as intimidating or tall as the building itself.
I understood why the wave increase gradually, it Is just because the level of the wave from the ocean bottom gets shortly thru the distance. It's all about innertial forces that pull the mass of water up AND finally breaks at the shore and flows on land quickly. Am I wrong?
Tsunamis form due to volcanic activity, most often after an earthquake occurs deep in the ocean that creates a massive wave, quickly gaining speed and power.
yes, its true that the entire body of water is in movement, but its still a wave, its just a large,wide wave due to displacement of the watercolumn.If you look at how a Tsunami forms,the structure of it moves in wave patterns from the epicenter of the origin that creates the tsunamis,usually there is more than one wave,that spreads out in a circular pattern,the diffrence is that a normal wave is made by winds and is on top of the body of water.
There is an error in the video. Usually when the tsunami reaches its final point that is the time when the height of the crest is the same as the depth of the trough. So there must be signs of water withdrawing meaning that there must be water splashes the white ones. Other than that good video.
good simulation,. In a tsunami,either created by earthquakes,or by other objects that displaces water,the whole water column is set in motion,. when approaching land it really doesnt rise up as one big wave like you show here, this shows a hollywood version of one. Instead the wave streches out and flattens in lenght, but still keeps it mass of water and force , from land it looks like a series of rolling waves,that just keeps on coming in towards land.Once it hits land it doesnt stop.
No esta mal pero para que se provoque un tsunami de esa manera es necesario que las placas tectonicas sean placas convergentes, es decir, una placa se mete por debajo de otra y la levanta provocando asi una subida gradual de la placa y provocando una reaccion en cadena en la superficie del agua.
sorry for my english but... This wave of, say, 20 or 30 meter we never see in video records ... much less reaching the top of ten-story buildings ... Tsunami is more like flushing a bathtub than throwing a bucket of water in a miniature city
If you know a lot about tsunamis, you would know that they are also waves. Just because a tsunami is bigger than a normal wave, doesn't mean that it is immune to gravity. All waves that have crested eventually break. Most tsunamis break offshore, because they aren't powerful enough. The real damage is flooding.
***** Actually when the tectonic plates moves it creates a force and disturbs the whole entire column of water which pushes the wave towards land the water would only go that way because of the sudden up shift of the seabed so you learn more and unlike natural waves created by wind it only moves the top column not the bottom part of the column
The first poster was correct. The Wall of water that hit japan was much WIDER in longitudinal length while the height was only about 15 to 20 feet. The water levels (on more than 100 videos) and water rose continuously for more than 30 or forty minutes. Not just a large wave like depicted in this video.
So the wave will just continue moving forwards even on land? I thought it was stoped as soon as it reached the beach and then it would fell like a tree and swap everything into the sea.
Oh, not really. Don't know exact technical terms but while tsunami is formed, one side of the wave is above the zero level, while the other side is below and they start move apart from each other in opposite directions. Now, depending on which side you’re on, you’ll see different symptoms of upcoming tsunami. This one you mentioned is on the “negative” side of the wave. I found some videos explaining this here on RU-vid… Take care.
Tsunami is the water waves which move in the form of transverse wave perpendicular to its direction producing due to the movement of fault beneath the earth water or earthquake ❤️
Does anyone know which software it is? Also, is it a correct representation of what happens in reality? TO my knowledge wave breaking should also occur. Another point, shouldn't the first wave originate from the shore to the middle of the ocean?
Tsunami move at hundreds of mph nearest to the fracture that caused them. You could be out in a boat in hundreds/thousands of feet of water and the wave, only half to a meter high, could pass right under you . It is when they hit the coastal shelf that they become compacted, slow wayyy down, and increase in height. Once past that shelf, that wall of water has nowhere to go, and it collapses, gaining speed again, heading inland at 10-30mph.
