Perth Basin Array

To assess the feasibility of using passive seismic techniques in difficult environments, a passive seismic experiment was undertaken in the onshore Perth Basin. The Perth Basin is a long, thin geological basin next to a transcrustal fault scarp in an urban environment. Data was collected from an array of 29 stations. These stations comprised a north–south transect from near Moora in the north to near Harvey in the south, with a shorter east–west transect near Moora and extending on to the adjacent Yilgarn Craton. Additional data were also acquired in the Perth metropolitan area from 10 more installations. The project also aimed to image the Moho in an attempt to learn more about the mechanism of the creation of the Perth Basin.
