Gonna be awful hard to tunnel at 10k below surface
I think the idea in the other post I read was if you were blowing up tunnels they would register at the depth from tunnels above. Deepest mine in the world is like 3.5km. so yes 10km is very deep . The question is is it normal for a earth quake to hit at 10km . I'm not really sure!
