Abstract

During 1969, the Mundaring Geophysical Observatory collected seismic refraction data from explosions used by the Bureau of Mineral Resources No. 2 seismic party in the southwest of Western Australia. The seismic party exploded 37 charges up to 4,500 kilograms on a traverse from Balladonia through Kalgoorlie to Perth. Two mobile Willmore seismographs and permanent seismographs at Mundaring and Kalgoorlie recorded the resultant seismic waves. Raw data for this survey are available on request from clientservices@ga.gov.au - Quote eCat# 76503

Lineage

During 1969, the Bureau of Mineral Resources No. 2 Seismic Party carried out seismic reflection probes along the Geotraverse from Balladonia, through Kalgoorlie, to Perth (Branson, 1971). The refracted waves from the explosions were recorded by the Mundaring Geophysical Observatory. The Seismological stations at Mundaring and Kalgoorlie; a semipermanent station at Southern Cross, and two roving field stations were used to record these events. The Meekatharra seismograph recorded one event. The project of recording refracted waves was to supplement data collected during project FRUMP (Gregson & Woad, 1968) which had the following broad aims: (a) To investigate the deep structure and thickness of the earthOs crust in the region of the south western Precambrian shield. Variations of the earth's crustal thickness occur, particularly near the edges of the continents, where these investigations should assist in determining the nature of the continent. (b) To investigate parameters of seismic waves in the upper part of the earth's mantle in this region. Geophysicists are interested in the structure of the globe as a whole, and particularly in the mantle beneath a stable shield, such as exists in South Western Australia. (c) A better knowledge of the structure of the earth's crust, upper mantle, and their parameters will enable the Mundaring Observatory to locate local tremors more accurately.
