What is HQ teleportation destruction range?

[mr.WHO]

I've been thinking about using something like nav beacon + sattelite to deduct if there is no bystanders in HQ teleportation.

Do we know what it the destroyction range when HQ is teleported?
I assume the destruction is only at destination, not in original location as well, right?

Definitely destination only. Original location had a ton of traders.

I think the radius is the radar range of stations, which is 40km.

Logically shouldn't it be plot size instead? So a cube rather than a sphere?
I mean the teleportation destruction seems to be fairly obviously for clearing out the jump destination so nothing bugs out than something they actually want.
