For the past 2 days, I have been observing microseisms gradually increasing 
in amplitude as hurricane Dennis moves northward along the Atlantic coast.  
Periods are in the 4 to 6 second range.  The amplitude was so great this 
morning that I had to increase the alarm threshold to keep from recording 
unwanted files.  

I would be interested in hearing from others who are, or who are not, 
receiving these microseisms and how far westward they can be detected.

Thanks.
