Tsunami would be bad. Not going to look it up but from memory there’s some volcano near Easter island that if sunk would wipe out entire east Coast US as far west as Ohio .
Emp’s have 900 mile radius?
Also there’s some super volcano out Midwest somewhere that would be catastrophic to entire US.
And no major catastrophies our side of the galaxy. Billions of years and Earths axis just happens to maintain an exact axis required to support life. And several galaxies including our own have a black hole at the center that apparently does no harm.
That super volcano is up at Jellystone. ;^)
It would be catastrophic.
It’s actually hard to fathom the size of the crater up there.
Luckily it has been dormant for along time too. Hopefully all these will remain so.
