A previous paper 
described two techniques developed at the University of Auckland, School
of Engineering for recording microtremors. In this paper, various possible methods of analysing such records, with emphasis on the discernment
 of frequency content, are outlined. Those which were found most useful in microtremor analysis
are described in more detail and examples of their use are given.
