Seismicity in Northern WA

Abstract

A new seismic monitoring network installed in northern Western Australia in October 2005 seeks to record low-level seismicity in the region, with a view to understanding event frequency, magnitude, location, geological controls on seismicity and deep-crustal structure that may be contributing to crustal weakness. Data from a network of eight semi-permanent stations, located at localities between Shark Bay and the Dampier area, complements data from an additional 80 stations that were deployed for shorter periods as part of other research projects at the ANU between 2000 and 2006. This dense network of seismometers provides the opportunity for a detailed analysis of seismicity and shallow- and deep-crustal structure in the northwest of WA.
