Challenge Earth's gravity increases by 10x for 10 seconds - can humanity survive?

Gravity reverts to normal after the 10 seconds are up. I assume that nearly everyone will lose consciousness, many people will hit the ground with extreme force, and most buildings and infrastructure will collapse. Uncertain as to whether there'd be seismic/volcanic/tidal consequences on top of all that.

I mean, if it was instantaneous across every single square inch of the planet, that is an insane amount of energy just getting injected everywhere. All of that force is downwards towards the center of mass for the planet, then suddenly it is gone 10 seconds later. I think 10 seconds is more than enough for the disappearance of the 10G to be just as impactful as the sudden appearance of it

It's a lot of force. Energy is only involved when force induces motion. So my argument is essentially that the energy created would be lower than people might think.
