Seismic characteristics of the sediments of the Perth Basin

Brian Gaull

Abstract

In October/November of 2001, a team from Geoscience Australia (G.A) observed natural background microtremors at over 3000 sites in the Perth Metropolitan Area (PMA). The paper discusses the reasons and the background behind this investigation, the methodology used and its limitations, the problems encountered, the results to date, as well as the recommendations for follow-up work. This work was funded and carried out under the auspices of The Cities Project of the Urban Geoscience Division of G.A.
