I’m pretty sure we don’t have a Tsar Bomba lying around anyway.
I once read somewhere that 4 or so of those 50MT firecrackers ,if they were detonated in a short span of time, placed correctly, could split the planet apart. Of course we have all read all sorts of things about nukes over the years, I just remember that as I thought it was interesting. No doubt, a 50MT is a big bang. Isn’t that what the Tsar was rated? Or was it more? Didn’t they actually reduce it some, because they were afraid the bomber couldn’t get away?
