"Beyond" is completely ambiguous in this case. Do you mean above or below?
Well obviously they mean below
Unless they mean beyond the reach of the flood waters.

#32This is a deeper dive on the stones and their locations. Please note that 317 stone tablets were built after the 2 tsunamis, 125 (40%) of them were washed away or destroyed by the 2011 tsunami. https://thefunambulist.net/magazine/cartography-power/incomp...
That suggests a possibly better strategy (though very long term): pepper the portion of the landscape believed to be safe with "it is safe to build here" monoliths, each as stable as a typical building, and over time only the ones that speak truly will remain. Would work for volcanoes and earthquakes as well.
It has been ∞ years since a tsunami washed away this stone.

Sadly, that's at least partially true. But rebuilding on a sight where a home was destroyed eliminates the information value (that this site isn't safe from tsunami) and the coverage is far from uniform/regular (so you can't tell if there are no buildings in an area because it was previously undeveloped or is unsafe).
‘How old are these buildings?’ would be wise to consider. This probably works for a variety of things and in many places.
Japan has a bad habit of considering buildings as disposable. Odd that a land with 1000 year old temples knocks down 40 year old houses with zero remorse, but that seems to be the case.

#34I love how this article, just like a tsunami stone, surfaces on HN every few years. It just shows even shorter cycles of collective memories :)

or its just a new round of 10,000 who are learning about this for the first time, just like you once were

1000 year old temples
Well it depends. Very important shrines are dismantled and rebuilt every 20 years, eg https://japanwoodcraftassociation.com/2020/02/13/traditions-...
There are lots of old houses in use and for sale in Japan, but many people prefer building a new house to renovating or maintaining an old one - partly for practical reasons, partly because newer structures are more likely to be earthquake-resilient, partly due to haunting.

It should also include the location of where the stone lived before the tsunami. That would help future archaeologists determine how big the tsunami was

IIRC the issue was the emergency diesel generators being flooded, preventing them from powering the emergency cooling pumps, resulting in the meltdowns from residual heat in the reactor cores and spent fuel pools. Various construction changes could have prevented this from happening: - the whole power plan being built higher up or further inland -> this would likely be quite a bit more expensive due to land availabil…
Another option is designing fail safe reactors. CANDU reactors designs are over 60 years old now and were built fail safe so that if outside power to the core is cut off the system would safe itself by dropping control rods which are held up by electromagnets into the core.
A reactor scram isn't necessarily enough -- you still have decay heat to worry about. In the case of Fukushima, the fission chain reaction was stopped but without cooling pumps the decay heat was still too much.

#39The Cascadia Subduction Zone earthquake of 1700 was dated using Japanese tsunami records: https://ui.adsabs.harvard.edu/abs/1996Natur.379..246S/abstra...
Can't wait for round 2!

#40Fun facts, Fukushima Daiichi Nuclear Power Plant was built beyond the warning limit of the tsunami stones. If those people that setup the tsunami stones are still alive during the incident they will have a kahuna of "I told you" moment.

...beyond the (possible) reach...(of whatever(waves in this case))
