Full description Over the five year period from May 1993 to April 1998 the Seismology Group at the Research School of Earth Sciences was engaged on a major project in observational seismology with the object of mapping the three-dimensional structure beneath the Australian continent. The project exploits the information on seismograms recorded at sites in Australia from earthquakes lying in the major earthquake belt to the north and east of the continent. Suitable events are quite frequent in the zone of seismicity which extends from Indonesia, through New Guinea to Fiji and then down through Tonga and New Zealand. Each of these earthquakes generate a number of different types of waves which travel through the Earth to the recording stations and acquire during their passage information about the seismic velocities along their path from source to receiver.
