What Would Happen If A Giant Tsunami Hit Florida?

Tsunami Hazard Zone

Can you imagine the devastation that would be caused if a massive wall of water several hundred feet high slammed into Florida at more than 100 miles an hour?  To many people such a scenario is impossible, but that is what people living along the Indian Ocean thought before the 2004 tsunami and that is what people living in Japan thought before the 2011 tsunami.  Throughout history, giant tsunamis have been relatively rare events, but they do happen.  Scientists tell us that a mega-tsunami can race across the open ocean at up to 500 miles an hour, and when they reach shore they can produce waves that are hundreds of feet high.  And even though authorities claim that the threat to Florida is “remote”, it might surprise you to learn that there are “Tsunami Hazard Zone” signs on Florida beaches.  If a highly unusual event (such as a giant meteor hitting the Atlantic Ocean) caused a giant tsunami that hit Florida, the devastation would be absolutely unimaginable.

Most people don’t realize this, but almost the entire bottom half of Florida is just barely above sea level.  If a giant tsunami did hit Florida, there would be nothing to stop it from sweeping across the entire state…

South Florida has two big problems. The first is its remarkably flat topography. Half the area that surrounds Miami is less than five feet above sea level. Its highest natural elevation, a limestone ridge that runs from Palm Beach to just south of the city, averages a scant 12 feet. With just three feet of sea-level rise, more than a third of southern Florida will vanish; at six feet, more than half will be gone; if the seas rise 12 feet, South Florida will be little more than an isolated archipelago surrounded by abandoned buildings and crumbling overpasses. And the waters won’t just come in from the east – because the region is so flat, rising seas will come in nearly as fast from the west too, through the Everglades.

Even worse, South Florida sits above a vast and porous limestone plateau. “Imagine Swiss cheese, and you’ll have a pretty good idea what the rock under southern Florida looks like,” says Glenn Landers, a senior engineer at the U.S. Army Corps of Engineers. This means water moves around easily – it seeps into yards at high tide, bubbles up on golf courses, flows through underground caverns, corrodes building foundations from below. “Conventional sea walls and barriers are not effective here,” says Robert Daoust, an ecologist at ARCADIS, a Dutch firm that specializes in engineering solutions to rising seas.

Of course the authorities do all that they can to play down this potential threat.  They say that it is “highly unlikely” that a tsunami will ever hit Florida.  The following comes from the Florida Department of Environmental Protection

Although it is highly unlikely that a tsunami will impact Florida, it is not impossible. Floridians may also travel to locations where tsunamis are more likely. It is vital to know (and instruct children) that if the ocean suddenly recedes from the shore do not stand and stare. It is necessary immediately to run uphill or away from the shore and go to the highest location possible which may mean up the stairs of a substantial building. Everyone should be aware that no matter where in the world they are, if the sea is observed to recede from the shore, they should immediately run for high ground.

That last part is quite funny.  There is no “high ground” until you get to north Florida.  If a mega-tsunami strikes, there is going to be no place to hide.

And large tsunamis do happen in the Atlantic Ocean from time to time.  For example, National Geographic says that there have been 37 verified tsunamis in the Caribbean since 1498…

The Caribbean has been hit by 37 verified tsunamis since 1498. Some were generated locally and others were the result of events far away, such as the earthquake near Portugal.

In recent years, there have been some scientists that have been concerned about what would happen if there was a major earthquake in the Caribbean region or a volcanic eruption in the Canary Islands.  The following comes from CBS News

Meteorologist Bart Hagemeyer from the National Weather Service says an earthquake in the Caribbean region is likely to project wave energy more to the north and less toward Florida. But the direction can vary and much of the outcome depends on the amount of energy released by the earthquake.

The highly unlikely tsunami that Florida might keep in mind could come from across the Atlantic, created by the collapse of a volcano in the Canary Islands off the coast of Africa, say experts. For years, some have thought that the unstable volcanic structures in the Canary Islands would cause massive tsunamis to slam into the East Coast of the U.S. if they crumbled into the sea.

That would have the potential of a not just a garden-variety of tsunami, but a “mega-tsunami,” according to Hagemeyer.

So what would such a “mega-tsunami” look like?

Well, according to Dr. Simon Day and Dr. Steven Ward, it could produce a wall of water approximately 164 feet high

Dr Day, working in conjunction with Dr Steven Ward of the University of California, has now produced an updated model that predicts more accurately the size of the tsunami and the areas it will impact.

The model predicts that after the landslide the tsunami would travel a distance of almost 155 miles in just 10 minutes and would reach the Caribbean and Florida in eight or nine hours.

The forecast goes on to predict that a wall of water 164ft high could smash into the coasts of the Caribbean and Florida, while Brazil’s northern coast could be hit by a wave more than 130ft high.

Personally, however, I am convinced that the much greater potential threat comes from above.

According to the University of California at Santa Cruz website, if a massive asteroid were to crash into the Atlantic Ocean it could produce a giant tsunami with a wall of water as high as 400 feet that would slam into the east coast of the United States…

If an asteroid crashes into the Earth, it is likely to splash down somewhere in the oceans that cover 70 percent of the planet’s surface. Huge tsunami waves, spreading out from the impact site like the ripples from a rock tossed into a pond, would inundate heavily populated coastal areas. A computer simulation of an asteroid impact tsunami developed by scientists at the University of California, Santa Cruz, shows waves as high as 400 feet sweeping onto the Atlantic Coast of the United States.

In case you were wondering, yes, that would be absolutely catastrophic.

Major U.S. cities stretching from the tip of Florida all the way up to Maine would essentially be destroyed.  The following is an excerpt from an article posted on Modern Survival Blog

300 foot tsunami would be the probable devastation of the following major East Coast cities…

Portland, ME (~ 50′)
Boston, MA (~ 30′)
New Haven, CT (~ 50′)
Bridgeport, CT (~ 40′)
New York City, NY (~ 20′)
Jersey City, NJ (~ 30′)
Newark, NJ (~ 50′)
Atlantic City, NJ (~ 10′)
Wilmington, DE (~ 80′)
Philadelphia, PA (~ 40′)
Virginia Beach, VA (~ 10′)
Wilmington, NC (~ 20′)
Myrtle Beach, SC (~ 20′)
Charleston, SC (~ 10′)
Savannah, GA (~ 10′)
Daytona Beach, FL (less than 10′)
West Palm Beach, FL (less than 10′)
Fort Lauderdale, FL (less than 10′)
Miami, FL (less than 10′)

There are countless cities in between these coastal cities. The Eastern Seaboard of the United States includes some of the largest metropolitan areas in the country. Over one third of the country (more than 100 million people) live along the East Coast. Evacuation would be virtually impossible for most (except for the astute who act quickly) due to only hours notice, probable doubt, and the subsequent immediate gridlock that would follow.

Most scientists would tell you that the possibility of such a thing is extremely small.

But could it be possible that they are wrong?

At this point, more than 10,000 major near earth objects have been discovered, and about 10 percent of them are one kilometer or larger in size.

And there are many more out there that are still undiscovered.  In fact, scientists are discovering new ones all the time.

Sometimes, astronomers only spot them after they have passed our planet.

What is even more alarming is that the number of “fireball events” that are being recorded appears to be greatly increasing.  Just check out this chart from the American Meteor Society

So why is this happening?

Why are so many large rocks suddenly flying by so close to our planet?

Has something fundamentally changed?

And what is going to happen when a really giant rock slams into us one day?

    “Personally, however, I am convinced that the much greater potential threat comes from above.”

    The main difference is that an Asteroid or Comet Atlantic Ocean impact would guarantee a massive tsunami.

    “Earlier research by Dr Day had predicted that a future eruption of the Cumbre Vieja volcano in the Canary Islands was likely to cause the western flank of the mountain to slide into the sea.”

    1). The article leaves out that the island housing the Cumbre Vieja Volcano was built by the extinct volcano of the north end of the island and the active Cumbre Vieja of the southern end of the island. It built itself as a Stratavolcano more on par to Anuk Krakatau/Krakatoa than the Shield volcanoes like Hawaii.
    2). The article also leaves out that the risk of flank collapse is derived by an eruption a few years ago destabilized the western flank and starting a rift through the center of the island priming the western flank to be pushed into the Atlantic with a major eruption.

    Cumbre Vieja flank collapse is primed; it just needs the catalyst.

    Did you know that dozens of people are having dreams about a tsunami? The most interesting part of these dreams is most of them have them around 2am, and they report the waves to be hundreds of feet high, unlike other tsunami’s. Check out the videos, and comments of people having dreams about the EAST COAST, FLORIDA, and CALIFORNIA… It is really interesting that so many people are seeing the same thing. http://whygodreallyexists.com/archives/dividing-israels-land-judgement-for-the-united-states-visions

      That is true. I have been dreaming of huge tsunamis coming for about 20 years now. In the last tsunami dream I was on different shorelines and saw the wave coming in. In some places the waves were so tall the swept over the tops of hotels and in other places the wave was not quite as tall but devastating just the same. In these dreams I am never harmed but I can see everything. The water literally goes over my head and I am under the water. Of course these dreams could be literal or a metaphor for judgements to come. On 9/11 I heard the clock start ticking and I have been prepping ever since.

    • Hey Mr Fantasy

      Does anyone say anything about the Northern Gulf Coast of FL? The Forgotten/Emerald Coast?

  • Oldphartbsa

    The one to fear, and is most likely, is the avalanche from the Canary Islands. The volcano is on the edge of a huge rock formation that is poised to break off and slide into the Atlantic. From what I’ve read, the tsunami coming from that will exceed 600 feet in height and, hopefully, wipe out Washington DC.

    • corners

      if its large enough to wipe our our crooked politicians in DC, it will destroy our country. Just start with oil alone.All that infrastructure would be wiped out, as most of it is on the coast.

      • Oldphartbsa

        “if its large enough to wipe our our crooked politicians in DC, it will destroy our country.” No, that would SAVE our country.

    • Paul

      I thought the one we were looking out for was the island of LA palma…. I’m sure I misspelled that

  • Rolling Thunder

    I work a few hundred feet from the ocean here in Florida and live about 3 miles inland. Even if there is warning I’m sure the roads will be so congested there will be no escape. Guess I’ll try to get into a boat and hope for the best.

    • corners

      i think you would have to motor out to sea, into the tsunami. You are right though, most people couldnt leave even if they wanted too from all the congestion. And we have seen many times what humans do when their lives are on the line,Survival of the fittest kicks in for most.

    Funny you should mention Florida’s geology. My folks lived there for years. So about twice a year I visited for a couple of weeks, enjoyed home cooked meals, enjoyed Clearwater beach.
    I noticed that acid rain was causing a lot of sink holes. Occasionally a house or car was swallowed over night.
    The thing is Florida is a giant sandbar in the ocean. The limestone comes from the northern hard water flows over a very long time. If the limestone is eaten up by acid rain, it is very likely the entire state will be several feet below the ocean some time in the future. A giant ocean wave could happen and that might send the sands to the bottom. How much of a shallow water barrier is there off the Atlantic Coast of Florida? Where does the really deep Atlantic waters begin?
    Personally I have always thought of it as the retirement state. A place where humans go to die. Just like the legendary Elephant Burial Grounds of Africa.
    Just who would benefit if an entire state of senior citizens suddenly died? Well, Social Security, Medicare, Medicaid, Pension Funds, funeral homes if any bodies are found, not sure where it goes from there. But a good portion of the retirement debt of government would suddenly disappear. Oh well, one more conspiracy theory. The nearest safe place might be Kentucky or Ohio. Though the Tennessee mountains might be safe.
    There is a huge plain that depends on rain from the gulf stream. That also might change leaving the entire area in a huge drought that might not end ever. Systematic disasters seem to be the norm for planet Earth. So this is as likely as it is anywhere else on the planet.

    • MichaelfromTheEconomicCollapse

      Very interesting comment. Thanks for those points DJohn1.


    • puckles

      Sinkholes are happening everywhere in the world these days, not just in limestone areas, and there are multiple theories as to why this is happening. One I tend to credit is planetary expansion. We know it has happened in the past; why should it not now? It may well be influenced by solar events, which are likely the primary reason for “climate change,” which has existed for millennia–not a recent event, by far. The members of the IPCC, alas, are not geological historians; if they were, they would know better.

      • Lee

        Great points! If most humans could think in geologic time we’d be much better off. We understand days are hotter than nights. We understand summers are hotter than winters. No one freaks out when it starts snowing in the winter b/c we expect it. For some reason though no one seems to understand ice ages and how our current location in the universe effects our weather. So we are at the end of an ice age and it’s possibly warming up and everyone is freaking out when the reality is it’s heated and cooled since the beginning of time. There is a reason why our core is made of magma and we have earthquakes and volcanoes. If it weren’t for the world cooling down we wouldn’t exist right now. This rock will be heating up and cooling down much longer than we’ll be around.

    • Hey Mr Fantasy

      Depends. Where I’m from in Southern WV, we have sinkholes as well. It’s the same Karst topography as FL, just in mountain form. Supposedly the real reason for the sinkholes is the draining of the FL Aquifer for agriculture. Coal mining is supposedly responsible for the ones in WV. Whether or not this is true…well, who knows. But it makes sense to me (I am not a scientist though).

      I wonder about the Panhandle of FL, and the Northern Gulf. Would it affect that area? I hope not! FL is truly a beautiful, amazing state and it’s being destroyed by overpopulation and greedy scum developers that are bound and determined to squeeze every cent they can out of the rape of one of the most stunning places on God’s Earth. Kind of like the coal mines and WV. Sad that nothing can be done to stop it, mainly because people worship the Almighty Dollar more than anything else, and have zero respect for anything that doesn’t make them a buck. Sickening. I hate to say it but FL needs to be cleansed, I think God created it as a special piece of Heaven on Earth to give us an idea of how it will be…and we have ruined it. It’s just a tragedy all around, in every way.

      Acid rain doesn’t cause our sink holes. We get lots of rain. In our rainy season we get more rain in ten minutes than CA gets in a decade. Yet it’s still sunny out when it rains. Our rain isn’t really acidic especially when compared to national averages and especially the North East. Our rain reacts with carbon dioxide and decaying vegetation as it sinks/moves down thru the ground to gain it’s acidity. That acidic water erodes soil and rocks underground. That’s just one method to cause them though. Over withdrawal of ground water by humans is another. Movings lots of ground water from one spot and concentrating it in another is another cause. Artificially created ponds of surface water is another cause. Drilling new water wells is yet another. They’ve been happening for thousands of years. They happen all over the world. On to Florida… It’s not a place people go to die. I came here young for a highly lucrative career. I work for a company that’s full of young people doing the same thing. After bouncing all over the country I’ve found it to be the best place to live in America. No state taxes so we keep all of our salary. Low sales taxes too. Plenty of sunshine/blue skies/white clouds. Plenty of clean water/no droughts here. Green all year round. No winter. No snow. Great places to live that are clean and crime free and cost effective compared to most major cities (high end/high quality housing but not expensive). As an example I have a 5,000 square foot house here with pool/hot tub and three car garage/guest house that is the same price as my POS 475 square foot condo was in D.C. (which was cheaper than the one bedroom studio I rented in LA. Big city jobs with big city pay but not all the negatives of a big city. Cost of living and the American dream is easily attainable here compared to the rest of the country. Lots of outdoor activities year round. Awesome state and national parks/forrest etc. Awesome access to the some of the most beautiful beaches in North America. Close to all the cruise lines and Disney Parks. Close to the Bahamas and Caribbean. Lots of personal freedoms. Less restrictive than most states. Lots of lakes/rivers/parks. Great shopping. Great dining. Great boating. The reason I’m reading this article is to decide where to put my Lagoon 450 yacht. Respect your elders. They have lived long lives in crappy parts of the country and have acquired a great deal of life knowledge… they all come here for very good reasons.

    I was driving from Boca Raton to Lantana when a rock from high above slammed on my car’s windshield, I thought it was from someone, but it came from above. I realized that later. But I didn’t come back to search for the rock. A moonstone?
