I wonder how far the ground current from a lightning strike is reaching.
Assuming having two ground rods in a practicable distance and measuring the voltage (-drop) in between

Yup, I think so too. We seem to get quite a few of them now, expecially with L.L.M. stuff around now they are only going to get better at fooling us.

With reguards to the orignal post, a google suggests 30kA is in a lighting strike but once it hits ground its going to disapate very quickly.

A read of https://ledaelectronics.com.au/wp-conten...oEarth.pdf does show some examples of resistance per cm. Depending on soil and mosture it does change.

Also worth looking at,
https://engineering.stackexchange.com/qu...htning-rod

This talks about why a 13 mm / 0.5" bit of Lightning rod can keep a building safe even at 400 kA.

I would still suggest avoiding being in the path of it.
