Using a Synthetic Continental Array to Study the Earth's Interior

Abstract

A major field-based observation program (SKIPPY)is underway to synthesize an array covering the whole Australian continent, using a series of deployments of around 10 broadband seismometers for periods of 5 months at a time. The distance coverage from available events is very good, so that it is possible to build up composite record sections covering propagation from 10 to nearly 180°, with a full coverage of the body and surface wavefields. For deep events at regional ranges, the field arrays also yield good data on mantle reverberation patterns.
