Will Japan eventually slide out into the pacific ocean?

No because it has come the ocean bottum, via volcanos. Japan will get larger.

The seafloor on which the islands were built is continually moving northwestward across the hot spot at a rate of 7-9 cm per year.  The northwest Hawaii island chain actually merges along a rift line with the Aleutian Islands in Alaska, all part of the same family.  This has been going on for millions/billions of years.  Most of the islands, however, never meet a continental land mass, since islands formed from lava rock are highly unstable.  In fact, Molokai used to be part of a larger island since it was connected to Maui and Oahu in the past (they have a name for it, but I forgot).  There is evidence in Alaska of a tsunami caused by a large mass sliding into the ocean on the north side of this large, 3-part island, creating the world's tallest sea cliffs on Molokai (3000 feet tall).  Of course this happened LONG ago, but can happen at any time.  Most of the northeast sides of all of the Hawaiian islands are in danger of large avalanches into the sea because it is the predominantly windward side of the islands, creating large amounts of rainfall and thus increasing the instability and erosion.  And don't forget, earthquakes happen EVERY DAY.  All it takes is one big one and Alaska, Japan, California, Russia, Australia, and even Hawaii too  could feel the effects from the ensuing tsunami.

No.     It is certainly not possible in your lifetime, but could happen in a few tens or hundreds of millions of years (by that time Los Angeles may be much closer to San Francisco since the Pacific Plate has a northward movement in this region).  Los Angeles sits on top of a deep sedimentary basin; basically a several mile deep valley filled with sand, shale, and conglomerates. It also sits on the eastern edge of the Pacific Plate. Just across the plate boundary, which is the San Andreas fault, there has been relatively recent (geologically speaking) volcanic activity in the Mojave Desert, such as Pisgah, Sunshine, Amboy Craters, and the Cima Volcanic Range outside Baker CA. Cima has erupted as recently as 10,000 years before present. Volcanism in the Mojave area is likely because the crust of the North American plate that abuts the Pacific Plate is much thinner in that area. Beneath the San Gabriel Mountain range that borders the San Andreas fault there is a deep root of crust, making the Los Angeles basin safe from any volcanic activity in the near future. \n\nIf you have ever driven over Cajon Pass,the area near the truck weigh station at the top of the pass is near the location of the San Andreas fault, and when you travel north across this fault, you are crossing from the Pacific Tectonic Plate onto the North American Plate. \n\nHere is a paper on the crustal structure of the area:\nhttp://earth.usc.edu/~okaya/pdfs/fuis2001_larse1.pdf.\n\nHere is a National Park Service site that describes the Mojave:\nhttp://www2.nature.nps.gov/geology/parks/moja/\n\nThe movie is pure fantasy, and I'm sorry to disappoint you that it is not scientifically based.

Absoutly, there is a ridge subduction zone off the pacific coast that is moving at a good clip.  We know through laser tomography, that the surface of this subduction zone isn't as smooth as many other fault lines.  We know what will happen as soon as it 'buckles', a huge earthquake, followed, of course by a sub surface wave, making a tsunami.\n\nAs to when, no clue.  The plate at the subduction zone isn't moving at a constant clip, but random.  So hard to say.  Will it happen? Absoutly, when? Dunno.

OK, first of all, inhale. Your body needs oxygen crisis or no crisis.\n\nIt's not that this plate movement re-awakens a bunch of volcanoes, these volcanoes exist in the first place because of the process of subduction, which has been going on--[gasp]--for your entire lifetime and a few billion years before your birth.\n\nThere are several tectonic plates at play in the Pacific. The Pacific Plate seems to be moving in a northwesterly direction, judging by the formation and erosion of the Hawaiian Islands over a hot spot that stays stationary under the moving plate. This plate apparently changed direction abruptly many millions of years ago, judging by the direction of the Emperor Seamounts in relation to the Hawaiian Islands. The first link below shows the other oceanic and continental plates in the world, including those on the Pacific side.\n\nAs a general rule, the oceanic plates in the Pacific are subducted under the surrounding continental plates and into the mantle. If you placed a couple of tables edge to edge and seated a few kindergarten students around each one, the kindergarten students would push on the tables (it's just a thing that they do) until the edge of one managed to slip over or under the edge of the other. \n\nThat's similar to what happens with continental and oceanic plates, too. If an oceanic plate and a continental plate come edge to edge, it's usually the denser seafloor that will go under the other plate. The odds are closer to even if two continental plates collide (as in the collision of the Indian subcontinent with Asia that created the Himalayas) or if two ocean plates are pushing up against each other.\n\nAs far as giant or tsunami waves, we are unable to predict exactly where the next tsunami will come from, but here are three possibilities to keep us up at night:\n\n1) Huge earthquake off the coast of British Columbia/ Washington State/Oregon/ northern California. Such an earthquake hit along 600 miles in January of 1700, and it was about the magnitude of the one that created the Indian Ocean tsunamis in 2004. The 1700 quake also caused devastating tsunamis that did hit Japan and probably hit other places as well. Computer models have shown a series of tsunamis from such a quake hitting the Hawaiian islands on their way across the Pacific, and again on the way back, a "ricochet" effect, if you will. Unfortunately, I think that animation was taken off the web a year or two ago, or I would share it with you here.\n\n2) A volcano on the island of La Palma may collapse, creating a megatsunami hundreds of meters high to scour the coast of Africa and tsunamis of 10-25 meters to batter the eastern coast of the US.\n\n3) A 4,760 cubic mile chunk of the Big Island (Hawaii) falls into the ocean, creating a devastating tsunami around the Pacific. The island of Hawaii suffered two deadly tsunamis in the middle of the last century from earthquakes around the Pacific Rim (Alaska and Chile). The Pacific Rim would be just as vulnerable to tsunami's originating in Hawaii. \n\nSuch "slumps" have occured in Hawaii before. I live on the lower slopes of an extinct volcano that lost half its mass to a landslide a million and a half years ago.

The Pacific Ocean...if you know the answer, then why are you asking?
8834
Yes.  Any coastline has a chance of getting hit with a tsunami because the waves are created by underwater displacement and can be propagated around the world.

No.Tsunamis occur usally after there is an earthquake of a 7.0 maginitude under the ocean, for most tsunamis to occur the fault or the earthquake has to be under water and has to go up a reasonable mount of feet. Then it sends a wave which passes through a boey system and then that notifiys a the people on land.\nSince earthquakes are impossible to predict Tsunamis are too and that points also how often they occur. Not all earthquakes cause tsunamis, and if you heard of land one, it is most probaly it caused a underwater land slide or an out of water land slide which then crashes into the sea depending how big it is it will make anything to 1,000 foot wave.

Plate tectonics moves continents around in a cyclic pattern known as the Wilson Cycle. In about 250 million years in the future, we will again have a supercontinent.\n\nThe Paleomap Project has predicted what the earth will look like based on current evidence. The Atlantic Ocean will no longer exist, as North American will be forced up against Africa and Europe, and Indian Ocean may only remain as an inland sea.  Antarctica will again be at the South Pole and Australia will be pushed up against it. The southern part of South America will be adjoining Indonesia. \n\nThe area where the south Pacific is now is likely to have some new volcanic islands, but probably all of the currently existing islands will have been pushed up against a continent. The Pacific Ocean will be much larger than today and will cover half of the earth. \n\nHere is a map:\nhttp://www.scotese.com/future2.htm\n\nI would speculate that even further in the future as the supercontinent breaks up, it is likely that some portion of the supercontinent will move towards the South Pacific. \n\nVolcanism plays an important role in building continental plates, and is constantly adding continental material, but continental plates are composed primarily of less dense intrusive igneous rocks such as granite. Volcanoes produce extrusive igneous rocks, which do not make up the major parts of the continental land masses so volcanoes are not as important in continent building as other processes.  \n\nHere's a site that explains the Wilson Cycle:\nhttp://csmres.jmu.edu/geollab/fichter/Wilson/Wilson.html

Can, do and will get worse.\n\nFrom  Nunatsiaq News:\n\n"In the last century, three of the 10 largest earthquakes in the world have occurred in Alaska, and these produced deadly tsunamis. In 1958, a landslide caused by an earthquake sent a tsunami 524 metres high into Lihuya Bay, killing several fishermen and stripping the fiord of vegetation.\n\nThe presence of sea ice has lessened or "dampened" the impacts of most tsunamis in the Arctic Ocean. That's why Alan W. Harris, a senior research scientist at the Space Science Institute in California, maintains there's little possibility of a killer wave doing much damage in the Arctic and "only polar bears need worry about whether the ice damps the tsunami wave from an Arctic impact."\n\nBut in the future, with increased calving of glaciers and ice shelves, where massive hunks of ice break off and crash down into the water, there could be more Arctic tsunami-type waves, and, with less sea ice, these could have a larger, visible impact."

If tectonic plates move underwater it is possible to get a Tsunami (Means harbour Wave in Japanese) anywhere assuming the conditions are right.\nGenerally Tectonic plate shifts have to occur in the up/down motion (Regional uplift or subsidence) to cause a Tsunami. Once the underwater wave hits shallow water it will raise the sealevel due to the force of the underwater wave causing a Tsunami.\n\nThe West coast of the US would be at most risk from a Tsunami due to the Pacific rim being a hot bed of Tectonic  plate activity, in fact they already have a Pacific Tsunami early warning system (USGS).\n\nI am no expert but have seen countless documentaries and read books on the subject.

Yes, and the ocean floor does change shape and volume over time. One effect of tectonic activity is that the mid-ocean ridges sometimes increase in height and can cause gobal sea-level rise, or if they fall they will cause sea-level drop. Other tectonic activity may offset this rise by opening the oceans wider or making them narrower. Right now the Pacific Ocean is growing in width by about 4 centimeters per year. There are many other factors that can affect sea level though, including different types of plate tectonic movement and global temperature changes.\n\nVolume is defined as ( I quote):\n   "1. The amount of space occupied by a three-dimensional object or region of space, expressed in cubic units.\n   2. The capacity of such a region or of a specified container, expressed in cubic units." Source: http://dictionary.reference.com/search?q=volume\n\nWhen I refer to volume of the ocean basin, I am refering to the capacity (2). It does change.

Our coastlines would probably move inward. Estimates range all the way up to several hundred miles, though that's pretty extreme. Some of the more familiar islands, like Hawaii, Iceland, and Japan, might shrink significantly, or even disappear completely. World climates would change. Temperate zones would shrink, and there would probably be a period (possibly long) of some very stormy weather.

Well I don't know for sure, but I believe it will be on a cruise ship somewhere and to keep it on the American side it will probably happen before it leaves one of our ports.   A cruise ship is its on little island and the only place that have people of different origins with money. Everything else is happening on cruise ships why not that. I just wonder if the government has thought about that... but then again if the ship is out in the ocean it will be out of the US jurisdiction and our great Government will not care what happens to anybody on that ship let alone the American Citizens.
