If yes would you even notice?
If no how far away would you have to be to survive?

Still, it starts at well above escape velocity (but within a couple of orders of magnitude of it), so perhaps it'd make it to the other side. Would you get a lot of heat energy, but spread out over a few thousand km in a line, and so not that disruptive?
Prosthetic Conscience wrote:I did look for formulae for Hawking radiation; what I found seemed to say that a black hole of this magnitude would have a life of something like 10 billion years (it's around the size that they say would be 'primordial, but dying now'). So I suspect the momentary radiation, even over a few minutes inside the Earth, won't be huge.
Everything I say is a huge uneducated guess, of course. I suppose that every time it 'hit' a nucleus in the Earth, it would annihilate it (though how do black holes interact? By gravity, we know; do they react to the strong nuclear force in some way? Way, way over my head...). But yeah, perhaps not that much would happen, in the grand scheme of things.
Potemkin wrote:Black holes do not interact via the strong nuclear force. As the saying has it, "a black hole has no hair". Once its mass has collapsed into the singularity, and it is cloaked in an event horizon, the black hole exerts and feels only the gravitational force. And since the black hole would not and could not be stopped by any matter it encountered, it would actually do surprisingly little damage, since its kinetic energy would not be converted into heat and radiation. It would likely just bore a microscopic tunnel through you and then the Earth, and then continue on its merry way. You might not even notice it had hit you. Lol.
Prosthetic Conscience wrote:Interesting - I thought that since black holes can have electrical charge, it would still interact via the electromagnetic force, and so the strong nuclear force might be possible too.
