I was really hoping for someone to say it bounced off of the ice wall or something. Sigh....
3DG already did, and Tom took him up on it... Wait, are you actually this dissociated from the things people here are saying?
To be accurate - I said that the repeating seismic waves from Krakatoa (36 hours apart, it is claimed) would not have repeated on an infinite flat earth UNLESS the waves were reflected back from something fairly close. The Ice Wall is the most likely candidate, I suppose.
I'm not claiming that the sound waves bounced off of the Ice wall - because I'm not claiming that the earth is flat or that the ice wall exists.
I'm saying that IF the earth were flat and IF seismic stations picked up regular repeats of these enormous seismic events THEN these waves would have to have been reflected off of something.
If we accept this as the FE explanation for these seismic readings - then unless both your seismograph and the source of those waves were in the precise center of the ice wall - then you'd expect to find doubled signals with a longer gap between them because you'd detect them on the way out - and on the way back from each side.
In truth (as someone pointed out) the waves would soon start interfering with each other and you'd pretty soon be unable to get a clear signal.
However, in RET, there is no problem with a coherent wave passing a particular point over and over again at a regular interval until friction eventually robs it of it's energy to the point where it becomes undetectable.
The problem I have with the Krakatoa story is that 36 hours seems to be an awful long time...but since I can't find a reference for the speed of SURFACE waves - it's not impossible.
Thanks for posting. After I showed Peter the error of his thinking he bailed. I'm sure he'd say he stopped posting because I was too stupid or something, he is extremely predictable, but I have that pesky data. Being so heavily studied, the event really is VERY solid proof of a round Earth. (as if that is needed)
36 hours matches very closely the travel time of the Chelybinsk infrasound waves. (35 hours)
Yeah - I guess so.
Wikipedia told me that the speed of "p-waves" is 5000 m/s and that "s-waves" are only 60% of that speed...so 3,000 m/s...so with the circumference of the Earth being 40 million meters, that would produce circumnavigation times of 2 to 3 hours...not 36 hours.
However, those speeds are for "body waves" - the ones that go more directly through the mantle and crust. I've been unable to find speeds for "surface waves" - which are the ones that would travel around the earth multiple times - and which had the right orientation for the detection results after Krakatoa.
However, in an infinite flat earth, there is no reasonable grounds for there to be any reflection of seismic waves and the seismic results from either of these big events should have been one p-wave within (at most) two hours, and one s-wave within (at most) three hours - plus a surface wave some unknown time afterwards...and then no more. That's CLEARLY not what the data shows.
My suggestion that the seismic waves would bounce off of the Ice Cliff was factetious. There is no way something just 200 meters high and made of low-density ice could reflect a seismic wave like that. We don't even see reflections from mountain ranges ten times that high made of solid granite...so it's not plausible.
If I were a Flat Earther, I'd be seriously thinking about claiming that there is a layer of Kryptonite 324,000 kilometers below the surface of the Flat Earth and that p-waves were reflected back upwards and downwards between the surface of the Earth and the Kryptonite.
The trouble with this entire thread is that it requires a lot of deep knowledge about seismology, that I don't think anyone here has. I wouldn't rate this as a "solid" disproof of FET - although it definitely points in that direction.
Sunsets, however...HA!
