Japan Plans For 100ft Tsunami (thesun.ie)
schwit1 shares a report from The Times: It will shake houses and tall buildings, and unleash a 100ft tsunami on one of the most densely populated and industrialized coastlines in the world. It could kill and injure close to a million people. It will almost certainly come in the next few decades. Now, the Japanese government is making plans to evacuate millions of people in anticipation of what could be one of the worst natural disasters in history (Warning: source may be paywalled; alternative source). It is known as the Nankai Trough megaquake. The Japanese government has previously estimated that there is a 70 to 80 percent chance that such an event will take place in the next 30 years and that the earthquake, and subsequent tsunami, could kill 323,000 people and injure 623,000. Unfortunately, the report doesn't outline how the government plans to get people out of harm's way. The city with the most people in the danger zone is Nagoya, Japan's fourth largest city and home to 2.3 million people. "The home of the nation's industry Hamamatsu is also at risk and home to over 800,000 people," reports The Irish Sun.

Please, please adopt the metric system like the rest of the world. :(
Really, that's how people think. "It's a little cheaper [or more convenient or whatever] to live here today, so that's where I'll live." Sure, there's going to be an earthquake [or a flood or a fire or whatever] at some point in the future, but each individual making the decision only knows for sure about the current situation, and the future gets dealt with [or not] when it arrives. It's all a matter of time, eh?
At first (in time) I thought the first-post joke about a wall and the riposte about #PresidentTweety were just trollish games, but now I'm seeing things differently. It must be that some of the people supporting the #OrangeOxyMoron are [not] thinking in the same way.
The topic is hot here on Mars. (I still like that euphemistic destination one of my friends selected when I left Austin so many years ago...) My wife actually went up to help some of the victims of the triple disaster in Fukushima, where they did have walls that were supposed to help with the tsunami part of the mess. Didn't work so well. I think the most amazing result is that TEPCo still exists. Talk about a toxic brand.
The local cycle time for major earthquakes right here has been around 70 years. On that basis we're about 40 years overdue. You have a nice day, too.
By the way, I actually think Murphy's Law is about to get invoked. We won't get the big quake here until the rest of the world is completely incapacitated and unable to help out. The Donald is wrecking as fast as he can, so it may be soon.
Freedom = (Meaningful - Coerced) Choice != (Speech | Beer^2), and sad sock puppets' bad mods avail them naught.
I'm just sayin'. Imagine someone riding that mother fucker with a GoPro.
Underground bunkers. This will be the super easy. Ideally, they could just fly the city out of harms way. Anyone who thinks they cannot do this now has not watched anime.
Didn't think so.

to weather such a storm. Not with their economy being what it is. It's times like this that I wish folks could stop wasting time dropping bombs and fighting over who's God is God and just get stuff done.

People seem to have forgotten the 1923 earthquake and FIRE that destroyed Yokohama and a quarter million lives, without even a hint of a tsunami!
It was around 7am and people getting breakfast off of wood or coal fires in the homes leading up the hill from Yokohama bay. The quake hit, upset all the cooking fires and lit the upper reaches of the hill on fire and the Westerly winds blowing over the top pushed the fire ... and people who survived down toward the bay.
Unfortunately, the major industrial port's fuel tanks burst covering it with fuel and oil which quickly lit off when the windborn fires reached the bay and very few people survived. The photos taken by local photographers just after the ashes cooled made Yokohama look almost exactly like Hiroshima after the nuclear bomb. I have a two volume set of books summarizing the events.
Yokohama harbor had about a 9.5 foot elevation change after the earthquake in some areas. This is a similar elevation change to what was detected in the Seattle area after an earthquake in the early 1700s before westerners populated the area. It is predicted to hit again. Good reason Amazon is looking for another location!
In other words, there are a whole lot of ways to destroy a city in & after an earthquake and then isolate people after the earthquake when the ground elevation changes wipe out roads, bridges, trains, etc.
Godzirrrrrrrraaaaaaaaaa!!!!!!
that thing could make anything disappear.
Japan has a big aging population problem. Also a tsunami problem for certain cities. Seems like converting those cities to retirement communities is a solution to both.
How about developing a system that predicts the earthquakes and volcanoes eruption and couple the seismological data with historical records ?

Short of elevating the entirety of Japan 120 ft, I doubt there's anything that can be done, besides prepare a "thoughts and prayers" speech for the aftermath. A 100 FT wall of water will not be stopped by anything humans can currently build. Getting more than three people on board with a successful evacuation plan? Forget it. If the risk is that predictable and great, it seems like a tax-incentive based phase out of the area might work better than an evacuation plan.
Oh children. Japan used to have their very own Slashdot.
If the same thing was threatening the coast of NY or Florida or California, I can see crossover between the climate-deniers and the trough-deniers.
Those crazy scientists! There is no trough! It's a hoax! Don't buy into it people! And even if there is a trough, it's not full of tsunami germs. It hasn't been taking earthquake vitamins. It's not an accident waiting to happen, it's just an irrigation ditch. And even an quake or tsunami could happen, it's Godzilla-related, not nature. Godzilla's been doing this for millions of eons. And even if it was nature-related and it happened, there's nothing we can do about it, so why jack up our taxes and spend all that tax money trying to save people who disagree with me? So yea. Why should I be forced to pay taxes to save libtards?!?!
Lather, rinse, repeat.
The Russians have won. They have made the world a cesspool of distrust, greed, fear and hate.
Can airlift for a while until settles. if during a typhoon then those survival balls might be better but take up more space. Neither full proof but odds improve.
This is about this slashdot, of course ; Japanese people don't read this one, and thus don't care about what "ft" is. Duh, have to explain everything...

... we should build a wall ...along the west coast!
That is what the Fukashima was all about. Forget about the millions that might drown, focus on the fact that some deadly radiation could escape that kills as many as dozens of people.
...to set up a defense system against Kaiju.
That's a negative, Ghost Rider. I have been working in *research* at a *lab* with *air* that has much *force* for almost 30 years. We still use fucking RANKINE. You won't find a single metric tool in our toolboxes. We still have operational PDP-11s and AS400s, Sun SPARCS, and Pentium 90s.
Go be smart elsewhere. You failed at it here.
Drill an underwater well, put a nuke there, evacuate everyone, boom! Problem solved.
It's interesting that Japan and California actually plan for major earthquakes whereas planning for a repetition of the 1811 New Madrid earthquakes in SouthEast Missouri seems to be virtually nonexistent.

As cool as the metric system is, one of the advantages of Imperial units is that they're based on intuitive measures. You just have to tell the Japanese person one time, "a foot is about the length of your foot with your shoes on," and they will forever know how long a foot is.
Unfortunately, going the other way (imperial to metric) is not so intuitive, which is one of the reasons why Americans have thus far resisted the metric system. I was taught the metric system in the 1970s when the U.S. was attempting to switch. About the only measures which i thought were intuitive were your finger being about 1 cm wide, and your hand about 1 dm wide (not that anyone uses decimeters). Alas, it's called a centimeter and not a fingermeter, and decimeter instead of handmeter. So the only way to learn it is through brute memorization. Unlike a foot being the length of a foot.
c.f. teaspoon vs milliliter, horsepower vs Watt, atmosphere vs Pascals, grain vs gram. The only cool relationship I think the metric system has is that 1 liter of water weighs 1 kg.
Evidence suggests that walls cause tsunamis - big blue ones.
Nah. The coming Trump recession will make everything disappear.
...nor to I play one on television. So if this sounds stupid please be gentle.
The past few years there has been a lot of talk about rail guns. Which makes me wonder...
Line up a bunch of rail guns and fire whatever into the wall of water. Would this destabilize the wave and push for force of it away from the shore? Or at least diminish it's size.
Kind of like pulling a bottom Jenga and having the pile fall forward. Thus stopping it short of hitting any buildings.
Hey, if it's stupid and wrong, sorry. Just trying to help.
Care killed the cat, but satisfaction brought it back.
Absolutely false and ignorant statement
I live in southern Japan under the threat of the Nanaki trough earthquake.
> Unfortunately, the report doesn't outline how the government plans to get people out of harm's way.
My local area is expected to be about 7m under water (roughly 22 feet for you Neanderthals) and there are yearly evacuation drills, tsunami siren tests, tall buildings have agreed to be shelters and a lot of money poured into awareness and prep. Everyone is encouraged to work our their evac plan and meeting points in advanced, and most have some form of a bug-out bag. Where I live in particular the elevation is low and there are few tall buildings. Many area senior citizens have a bit of a fatalistic attitude of if everyone prepares but if it happens, they will do what they can but beyond that, who knows.
Seems odd that Japan is planning for a tsunami that is such a round number when measured in Imperial units. Are they actually planning for a 30m tsunami?

They should encircle the Island with big stone markers at the 100' wave height that say "do not build below this height" so that future generations don't have to retain the knowledge directly.
Like the ancient ones uphill from the Fukushima Daiichi plant.

Most anime just blow up Tokyo or some major metropolitan area and then aliens happen. I don't think a 100ft tall tsunami's been done yet.
Also, wouldn't Japan measure things in meters?
I applaud Japan for their forward thinking! I wish the US planned and prepared for stuff the way the Japanese do.
Probably much much smaller than a tsunami caused by the cascadia fault quake that we are due to experience any time now.
