Here is another link for you collection. Dr. Bedard has been persuing
several aspects of infrasound.
http://www.etl.noaa.gov/et1/infrasound/infrasonic.html This paper will give
you some ideas of the frequencies involved for several infrasonic signals.
I have found the Hayward site at SMU to be the best for building and
testing a detector.
I have also been slowly building a detector. based on the Validyne sensor.
http://www.validyne.com/ I will be using soaker hoses for a spatial
filter. My main interest however is for tornado detection rather than quakes.
During my web browsing I read that you could download data from some of the
infrasonic arrays via AutoDRM. So far I have been unable to do this. Has
anyone else tried?
