Tsunamis are unlike wind-generated waves, which many of us may have observed on a local lake or at a coastal beach, in that they are characterized as shallow-water waves, with long periods and wave lengths. The wind-generated swell one sees at a California beach, for example, spawned by a storm out in the Pacific and rhythmically rolling in, one wave after another, might have a period of about 10 seconds and a wave length of 150 m. A tsunami, on the other hand, can have a wavelength in excess of 100 km and period on the order of one hour. \nAs a result of their long wave lengths, tsunamis behave as shallow-water waves. A wave becomes a shallow-water wave when the ratio between the water depth and its wave length gets very small. Shallow-water waves move at a speed that is equal to the square root of the product of the acceleration of gravity (9.8 m/s/s) and the water depth - let's see what this implies: In the Pacific Ocean, where the typical water depth is about 4000 m, a tsunami travels at about 200 m/s, or over 700 km/hr. Because the rate at which a wave loses its energy is inversely related to its wave length, tsunamis not only propagate at high speeds, they can also travel great, transoceanic distances with limited energy losses.

when you travel faster than the speed of sound.

Methane gas can create large bubbles that can bring down ships and low flying planes.  Rogue waves up to 100 feet have also been documented in that area which can sink ships.  Also, and you can do some research on this,  the earth's magnetic field is changing greatly in many places all over the world, and this can interfere with instruments.  We have found some ships and planes, but not all.  I don't think we have the technology yet to send robots by themselves under the ocean. If we did, we wouldn't still be using those little unmanned research subs that are connected to ships.  Perhaps we can do it, but it's too expensive for now.

The speed of light and other EM waves (in a vacuum) is:\n299,792,458 meters per second\n\nThe speed of sound (at sea level) is:\n340.29 meters per second\n\nThe ratio is 880,991 times faster.\nThe difference is 299,792,118 m/s faster.\n\nOr the simple answer is about a million times faster.\nThe even simpler answer is *lots* faster!\n\nThis also explains why you see far away lightning long before you hear the thunder clap (except in the movies).

Ocean Waves are mechanical waves that propagate along the interface between water and air; the restoring force is provided by gravity, and so they are often referred to as surface gravity waves. As the wind blows, pressure and friction forces perturb the equilibrium of the ocean surface. These forces transfer energy from the air to the water, forming waves. In the case of monochromatic linear plane waves in deep water, particles near the surface move in circular paths, making ocean surface waves a combination of longitudinal (back and forth) and transverse (up and down) wave motions. When waves propagate in shallow water, (where the depth is less than half the wavelength) the particle trajectories are compressed into ellipses. As the wave amplitude (height) increases, the particle paths no longer form closed orbits; rather, after the passage of each crest, particles are displaced a little forward from their previous positions, a phenomenon known as Stokes drift. A good illustration of the wave motion is given by *Prof. Robert Dalrymple Java applet

Ok.. listen.. you have to think about this one a little bit\n\nIF everytime a lighting hit the water, everything got electrocuted, then there would be no fish in the sea.. so people that said that are not thinking right.. \n\nnow.. how far do you have to be\nLighting will try to reach ground right? thats the way it works? so it will find the fastest way down.. now Im going out on a limb here, but salt water conducts electricity pretty damn well.. probably better than a human body.. so my guess is, lightning will go straight down into the ocean floor.. \n\nnow.. this doesnt mean you wont die if its near you, because some electric current might choose a different path, but I would say if you are outside of 100 meters you would be ok. But I would get out of the water when a big storm is coming.. not because of lightning, but because the waves might be too strong to swim in

The highest wave on Lake Erie in 2005 was 8.2 feet, not terribly impressive.  A lake, even one as large as Erie, lacks the large scale movement of water that can generate the rogue waves sometimes seen on the opean seas.  For the same reason, lack of large scale movement, a significant tsunami could probably not happen on the lake.  A tsunami has a wavelenth of hundreds of miles, which means that Lake Erie doesn't have enough space for a tsunami to even rock back and forth once.

Ahhhh, an X-men question!  No doubt I can bring a lot of knowledge to this question.\n\nLet us begin by checking out the combatants.\n\nStorm and Rogue are indeed powerful; but it's the powers that matter here - while they both have flight, the crux of the matter lies within Storm's weather powers versus Rogue's power absorption, her invulnerability and strength.\n\nThe thing is, Rogue is nothing to sneeze at, considering that she's been a leader of the X-men for some time now, and she has had success in small-unit tactics as well as single fighting - however, Storm has also been the leader of the X-men as well, AND she has had vast experience in one-on-one fighting (check out her battles with the then-leader of the Morlocks, Callisto!).\n\nIt really boils down to the fact that these two parties know each other's skills and abilities.  Storm knows that Rogue can hit and hit HARD, but her main weakness is the fact that Rogue has to get in close to use her absorption powers.  Of course, Rogue with Sunfire's powers can use her fireballs as a long distance weapon, but that's right into Storm's territory - Storm controls the skies, so to speak.\n\nShe could snuff out the fireballs, keep her distance in the sky AWAY from Rogue and whip up tornadoes, hurricanes, hail, the kitchen sink, you name it at Rogue and Rogue wouldn't be able to counter all that.  That said, Rogue would be able to take a lot of punishment, but Storm is too crafty to let Rogue in close to drain her powers.\n\nI'd give this battle to Storm, with her lightning and her tempest winds.

As with any thermonuclear explosion, you obtain a huge amount of radiated energy in a very small location in a very small amount of time.  This radiated energy would be absorbed by the surrounding ocean water very quickly.  This would cause a HUGE amount of water around the detonation site to flash-boil and expand rapidly.  This would create a propagating hydrostatic shock wave that would be felt all throughout the Pacific, mostly in the form of tidal waves.  These tidal waves will likely be fairly small, however depending upon the composition of the ocean floor, it may also let loose alot of rock and cause some underwater avalanches (another common source of tidal waves, esp. the bigger ones).\n\nDepending upon the depth of the detonation, very few of the radiated photons may actually reach the surface, and thus almost all of the energy will be consumed by water.  Besides no "blinding flash", this would also mean that the visible "water explosion" made up of mostly vapor would be larger than the equivalent land- or airburst vapor cloud.  If close enough to the surface, the flash-boiled water would quickly rise and break the surface with a large gaseous explosion, and the vapor would climb into the air and spread once it achieves altitude, so yes the "mushroom cloud" will still form.  If it were very deep, though, the gasses would eventually spread and, to some extent, dissipate, resulting in just a lot of surface turbulence and foamed gasses.\n\nDo some research on "Operation Crossroads", which were two U.S. nuclear detonation tests in 1946.  ABLE was an airburst at 158m, and BAKER was 27m underwater (yes, super-shallow, but it gives you a fair starting point).  There have been other underwater nuclear test detonations by various countries, but their speifics escape my memory at the moment.  :p

i suppose it depends on the car.  there are a few cars that are jet powered that can travel faster than the speed of sound.

Well,  there is a new island forming just south of the big island.  It is about 3000 feet under sea, and is not expected to break the surface of the ocean for another 10,000 years.  I'd say that is pretty fast in geological terms.

The tsunami question makes me think hard...I've thought about this many times before. \n\nA nuclear explosion starts as a radiative shock which degenerates into a supercritical shock, and so on, until all that remains is a volume of gas surrounded by an expanding train of sound waves.  In water, the question would come down to the equilibrium volume of water vapor produced at the depth of the explosion.  That would primarily depend on the water pressure at that depth and the total yield, I think.\n\nI simply don't have the expertise to calculate that figure, but I suspect the total displacement would be relatively small, even for the largest weapons ever fielded.\n\nI suspect little of the energy released would ultimately be partitioned into work (mechanical lifting)...thus any tsunami would probably be small and of a relatively short wavelength.\n\nVery interesting problem to consider.

300 meters (or 1000 feet) is about as far as a human being can go without the aid of a vessel. Dive depth records are a little over 300 m.\n\nThe Eiffel Tower is 300 meters tall, which is not very far at all considering how deep the ocean goes. The ruins of the Titanic, for example, are at a depth of 3,800 meters (which is about 2.5 miles). The pressure at that depth is over three tons per square inch - enough to crush you in an instant!

false sound moves at 331 m/s or about .20miles / second so 7 seconds between sound and lightning is about 1.4 miles away

Hi. I think it deals more with the interaction of radiation with particles (or a particle) than with speed. At any non-relativistic speed (less than .1 'c' say) the wavelength would not be infinite or unbounded. Just my opinion.
