how far inland would a mile high tsunami travel
I think they cited something in the 30-meter range. How strong is a tsunami? Then water explodes away from a raw orange-white crater. More specifically, I’m wondering if I’m absolutely safe here in southern Nevada. I´d be more concerned about the brimstone and hellfire raining from the sky, the meteorite that slammed on Yucatan 65 million years ago created a tsunami that washed Mexico and Texas, it didn´t make it all the way to Nevada, AFAIK. Remember, Long or Strong, Get Gone. I am the only one picturing Chorpler being chased by a tsunami wave as Leslie Nielsen in Wrongfully Accused was chased by a locomotive?? How far would a 100 foot tsunami travel? This makes tsunamis far more powerful. Some water spills east into Mexico; some west across Baja to the Pacific. It is very old crustal rock, and very brittle as such things go. Tsunamis can travel at speeds of about 500 miles or 805 kilometers an hour, almost as fast as a jet plane. If you choose to believe this could happen, it would be estimated that the wave would travel inland 20 miles all along the Atlantic coast. I know that we get a lot of storms from that direction; according to my Geology 101 professor, that is because there aren’t any high mountains in between us and the Gulf of California, so the moist sea air isn’t forced up to a high altitude where it sheds its water as rain before reaching us, as happens with the air coming over California when it reaches the Sierra Nevadas. If you are unable to evacuate but are near a multi-story, reinforced-concrete building, go to the third floor or higher. It would of course stay longer in low-lying areas, and retreat at once from higher altitudes. Models of coastal topography were included to show how far inland flooding was likely to occur. They generally do not travel very far inland. When a tsunami comes ashore, areas less than 25 feet above sea level and within a mile of the sea will be in the greatest danger. So you´d need an even larger rock for that. Tsunami inundation is the horizontal, inland penetration of waves from the shoreline. The topography determines how far inland a tsunami can go. Two other boats were taken across the peninsula and out to sea and disappeared. The researchers based their simulation on a real asteroid known to be on course for a close encounter with Earth eight centuries from now. The waves that travel inland a considerable distance are caused by events that displace a lot of water, such as an earthquake or landslide (assuming that the body of water that the land slide falls into is relatively small) but the asteroid does not do this. One in a bay in Alaska, I think it was Alaska, resulted in a wave 1500’ high that washed right over a peninsula. But, how likely is it to happen? Walk, run or cycle if at all possible to reduce the chances of getting stuck in traffic congestion. How far inland would a 100 foot tsunami travel? AcehMarch 30, 2014This article is more than 2 years old. With wave speeds that can reach as much as 435 miles per hour, a tsunami can travel as far inland as 10 miles, depending on the slope and the shape of the shoreline that it is traveling across. A … The worst-cast simulation assumed the impact of a rocky asteroid three miles … The Sea of Cortez is as warm as bathwater and as calm as a lake, a playground for swimmers and sailors. It depends - greatly - on the wavelength of the tsunami. And is my area, and power source, safe? So, does anybody know how far, in general, a wave could possibly wash inland? Simulations Show Tsunami Threat in Washington State. 10 miles. Hmmm. The landslips in Alaska didn’t destroy California or Hawaii, for instance. The 3 mile wave could have the potential to travel far inland. A ship or submarine on the surface in deep water will be fine. I recall reading in a book in high school (I believe the book was The Atlas of Natural Disasters) that there’s evidence of a 3,000 foot tidal wave in the north Pacific about forty million years back. oh yeah, another question, would anyone be alive to see the tsunami wave? The wave height would be incredible but it would lose momentum rather quickly as it’s wave length increases and it encounters obstacles on land that absorb its energy. If an asteroid of that size were to “fall” from orbit. In 1992, tsunami waves crashed into the front of an Indonesian island, split in two to wrap around the island, and then recombined to destroy … There were several places where the tsunami went a lot further than a mile inland, and many, many where it did not. But it would result from a wave generated by the collapse of a rather enormous landmass into the oceans. A 3 mile high wave hitting Europe is impossible … When the shaking stops, if there are natural signs or official warnings of a tsunami, then move immediately to a safe place as high and as far inland as possible. But the ocean’s pretty big. So if you’re living 10,000 feet above ground in your area and can within stand the original force of such an event, things look A-OK for you. I've been trying to find you an easy answer but there really isn't one. They hit low-lying areas and roll inland, or move up river valleys. Style, only style.”). Based upon internet estimates of the land mass of the earth and volume of water of all oceans and seas, in the somewhat(?) But what with the recent Indian Ocean tsunami and the whole “The minor planet 2004MN4 might impact the earth on Friday, April 13th, 2029!” furor that was going on at the same time, I’ve been wondering about this more exotic danger recently. Most tsunamis are less than 10 feet high when they hit land, but they can reach more than 100 feet high. An extremely tall wave would be produced but it would lack the forward momentum to travel inland to the extent that you might think. Northern Tennessee?? One drops toward the mouth of the Sea of Cortez until it touches water between the prongs. A tsunami run-up map indicates how far a tsunami will travel inland based on the continental shelf and strength of the tsunami. New Zealand is hit by TWO highly effective earthquakes registering greater than 7.0 on the Richter scale inside hours of one another – sending residents alongside 100 miles of coast fleeing inland after tsunami warnings 7.3-magnitude earthquake struck off the coast of NZ’s North Island at 2.27am It was adopted by a 7.4-magnitude quake at … Well, obviously there would be further concerns if a sufficiently large meteorite hit the ocean – Lucifer’s Hammer and Footfall detail those further concerns quite nicely. No tsunami wave has ever been 200 feet tall, so you would not be at risk if you are not in a river valley that might allow a tsunami to get pushed way inland. On an onobstructed beach with a slope of 10’/mile a 30’ wave would go somewhat less than 3 miles depending on the friction losses. There are a lot of variables to consider for this question, the primary being the velocity of the asteroid. South Florida, Louisiana and southeast Texas are the parts of the United States that offer the most glaring examples of where a Richter 9 or greater spawned Tsunami could head farthest inland. When a tsunami comes ashore, areas less than 25 feet above sea level and within a mile of the sea will be in the greatest danger. that's terrifying! Mock ups show just how damaging a tsunami would be for California. Then they recede, and multi-wave tsunamis recede and then advance again. By understanding where and how far a tsunami will travel inland, government agencies can determine proper zoning and building codes. Oh gosh! When a tsunami comes ashore, areas less than 25 feet above sea level and within a mile of the sea will be in the greatest danger. One of them, the BBC’s Horizon program Mega-Tsunami: Wave of Destruction, discussed the tremendous tsunamis that can be generated by landslides, and at one point there was mention of the incredible tsunamis that could be generated by large meteorite or comet impacts. The 3 mile wave could have the potential to travel far inland. Keep in mind that most of southern Florida is less than a 150 feet above sea level, and a good portion is already covered with water. Based on how light behaves I would assume it diffracted at the edges of the bay exit and diminished as something like the the square of the distance. That tsunami would be able to travel long distances on the sea. But just off the coast, scientists say another danger lurks: several major faults capable of producing major earthquakes that could send tsunamis crashing into Los Angeles and San Diego. He demanded to know if any eyewitnesses were present for the Lituya Bay incident, because he just couldn’t believe a wave could be that high. Were you just watching the Discovery Channel? This area was under a shallow sea at the time of the probable impact and tidal wave. I’m skeptical about that theory. The landslips in Alaska didn’t destroy California or Hawaii, for instance. As you say, investigation and studies of this phenomenon are pretty new. However, tsunamis can surge up to 10 miles inland. Wind waves, due to their short wavelength, often break onto the shore early and are highly turbulent. A tsunami can kill or injure people and damage or destroy buildings and infrastructure as waves come in and go out. I'm living in Florida so i already know i'd be done for. So, is there anywhere a meteorite or comet could impact that would create a tsunami big enough to reach Las Vegas? No tsunami wave has ever been 200 feet tall, so you would not be at risk if you are not in a river valley that might allow a tsunami to get pushed way inland. The tsunami was the deadliest in recorded history, taking 230,000 lives in a matter of hours. What Would Happen if a Tsunami Hit California? Tsunamis can travel at speeds of about 500 miles or 805 kilometers an hour, almost as fast as a jet plane. Like the earth being swathed in heavy cloud cover, crops dying en masse, global temperatures plunging, an ice age returning in all of its glory, civilization collapsing … all that good stuff. Anyway, if an event can make that big a wave, water is the least of your concerns. I was really hoping Gil was going to make it. On the Discovery program, IIRC, at least two experts said there is an upper limit for seismic-generated waves, or tsunami. in the somewhat(?) BUT in space, objects move at speeds in the ballpark of tens of miles PER SECOND. A wave 3,000 miles wide and half a kilometer high seems like an awful lot of water to be pushed inland by a tiny landslip barely a cubic mile in size. (this is assuming the velocity is fast enough to cause a massive wave but slow enough that a conventional wave would exist). Remember the Japan tsunami had a point of origin less than 100 miles from shore. 10 miles. No tsunami wave has ever been 200 feet tall, so you would not be at risk if you are not in a river valley that might allow a tsunami to get pushed way inland. “Sometimes you’re the windshield, sometimes you’re the bug.”. However, tsunamis can surge up to 10 miles inland. well we're at it the middle east. About 80% of tsunamis happen within the Pacific Ocean's “Ring of Fire.” The first wave of a tsunami is usually not the strongest, successive waves get bigger and stronger. I know that Australia would be completely swamped but what about Europe, Asia, north and south America, Africa. unlikely event all the water suddenly moved to land, it would have a uniform depth of roughly 1.8 miles. I gathered from the program that a lot depends upon the speed with which the rock falls. unlikely event all the water suddenly moved to land, it would have a uniform depth of roughly 1.8 miles. The bay appeared to be long and relatively narrow, a sort of a fjord, although there was no scale given as to it’s actual width. Can there be a tsunami in Los Angeles? How far inland would a mile high tsunami travel? The largest waves, in theory, could travel up to 16 miles inland. (The scientists did say that they were kinda blurry on … Hurricanes also drive the sea miles inward, putting people at risk. Let's see a mile and a half long comet or asteroid hits the ocean (like in Deep Impact), how far inland could the tsunami theoretically travel? The danger zone is near the coast, the rising seafloor concentrates all the energy of tsunami into a smaller and smaller space. well we're at it the middle east. It’s good to simply be aware of the possibilities, which may lead to further preparedness by some who’ve never thought of it before. Who could blame it for being afraid? By understanding where and how far a tsunami will travel inland, government agencies can determine proper zoning and building codes.
