Abstract
The objective of this research is to characterize the seismicity of South Africa, with emphasis on understanding the distribution and properties of mining-induced events in the Witwatersrand Basin. The study has focused on the two-year period from April, 1997 to May, 1999, when MIT and the Carnegie Institution of Washington, supported by the U.S. National Science Foundation and in cooperation with the University of Witwatersrand and a number of other research organizations in southern Africa, operated a temporary, 54-station array of broadband, three-component seismometers. This "Kaapvaal" array was distributed on a NE-SW axis from Cape Town, South Africa, to Masvingo, Zimbabwe, for the primary purpose of imaging the deep structure of the South African continent, but it also produced excellent recordings of regional seismicity.
