When i try to access the information on

I get file not found error

You should do a FFT analysis of your raw digital
data and see if you can extract the rotational rate of the funnel cloud from the data.
I would expect the rotational rate of a .75 mile
wide funnel with 100 mph wind speed to have
a rotational period near 84 seconds or less.

If the tornado was traveling at 60mph
then the rotational speed was probably
only about 100mph.

It made me sad that was unable to see the
seismic data, but what the hey, thats the story of my life.
