Hi Tom,
great post, interesting web page and entertaining question.
Many thanks for the good read and the info.

Being just a humble telecommunications engineer I got as far
as deciding on the leverage to your truck but then I got hung
up on the matter of the spring constant of your ground. :-(
I guess that comes out of the fact that the loaded tanker
was at the threshold in the noise of your short period
but way above the noise in your long period, but I am not
a seismologist, so I await with interest Sean-Thomas's input.

By the way, what is a root cellar ? :-( Not roots impinging from
that tree outside is it ?
I know about wine cellars.
