I dont mean to be rude, just I like to only use text and not HTML.
There are things in our machines called Interpreter programs.
They are more likely to be used in HTML kind of
formats.
But they can also be used with Text.

Commands used by interpreters can be any combination
of words or characters. Let your imagination go wild.
But such a program running in the background should be noticeable.

I simply don't like communicating via HTML or anything but
7 bit text. I dont always get what I want, so shrug your shoulders about
what I say. See below my real answer to your questions.

If you are looking for footfalls or autos bouncing in the bottom of a
tornado you will be looking for a low repetition rate
created by periodic high frequency sounds.
It is demodulation of noise you must consider.
Think only rotational rate of the vortex as well
as how such a rate may be manifested.
There is all kinds of evidence of intense
rivers of air, Vortexes that never touch the ground,
you need to be more specific if
looking for tornadoes only.
Beam a scanning laser across the housetops,
looking for anomalies in the index of refraction.
???

Also something I hesitate to speak of
which is integration of the data over time.
Integrate for many hours the noise before
searching for signals.
The noise should always be the same.
The signal will stand out as something not noise.
Seismology needs an engineering and science and mathematics noise expert.
it will never be a single person by him or her self which will have the 
answers.
That's all, I guess, I really am saying.

    5. change in elevation along the path may also play a part and may cause changes in size, frequency and noise produced...and is it possible to see the effects of bouncing storm cells collapsing  and hitting the ground .... even the tornado skips over some areas. There are photographs showing this skipping nature of tornadoes as well as the collapse of a storm cell.... but we haven't looked at our seismic data that close.

 The amateurs look for how far away I can detect a quake and how many reflections I can see.  while the professionals are looking at the depth of the quake and speed of the P wave because money exists if they can show an increased hazard in an area. I am not saying this direction of scientific endeavor is wrong but there are many other areas wanting time and effort. I wish I weren't so old.

How many tornadoes have you "experienced"; for me it is only two or three. I was about 200 yds away from one but it did not have a sound I could hear. I have interviewed many who experienced one...and earthquakes? Have you ever heard an earthquake? Yes I have --- at least three. sound is a common denominator! Why?

Question  --- Is the sound we hear in an earthquake caused only by surface waves? And for a tornado? Check you Lehmans. Look for a strong low maybe over 2000 miles away (or as close as the Great Lakes) --- one of your Lehmans will appear more "nervous" or active than the other. If we can detect 40 to 60 miles per hour disturbances when they are that far away, why couldn't we detect a 200 mph disturbance five miles away?
