If I didn't know better I could sure believe that you were seeing 
earth modes.  Another source could be from aliasing in the decimation 
process, but I don't think so.

You may want to check 
(Make sure this doesn't get split up in the e-mail.)


I'd probably want to ignore the maths, but they have good 
explanations and lists of the many frequencies that have been 
predicted and observed which you could check against what you are seeing.
