Today new, automated methods of tunneling create much
less ground movement.

USGS scientists have found that
ground movements from induced quakes are stronger just above the epicenter but
less so away from the immediate area, possibly because they tend to be shallower than natural ones.
However, the current data obtained suggests the opposite: an earthquake with an epicenter at the gates of the city, which would allow the people only very little time to find protection, but which would trigger
less powerful
ground movements.
If the intensity of the
movement is high enough and the transition on the
ground (amortization phase) is fast enough (0.2 seconds or
less), it's a true plyometric.
It feels much more settled than the BMW and
less prone to being pushed around — that could be a function of it carrying 10 or 20 per cent
less «
ground speed» — but the body
movements and the responses of the chassis are lazier.
At slow speeds the tires stay on the
ground — where the best traction is — longer and at higher speeds more
movement relative the body means
less movement transmitted through the truck and seat to your backside.
