On 22 January 1988 three earthquakes of Ms 6.3-6.7 struck 30 km southwest of Tennant Creek, N.T., Australia and produced approximately 32 km of surface faulting along two main scarps. An extensive survey program in the epicentral area was conducted in February and March, 1988 by the Australian Surveying and Land Information Group (AUSLIG) on behalf of the Bureau of Mineral Resources in order to quantify the deformation associated with the earthquakes. The survey program consisted of: (1) aerial photography of the fault scarps; (2) 170 km of double run levelling; (3) three detailed levelling profiles of 3 km length; (4) 85 geodimeter traverses across the scarps at intervals of 0.5 km along the scarp; (5) global positioning system (GPS) measurements of the coordinates of temporary benchmarks along the scarp and of portable seismograph stations; and (6) detailed surveying in selected areas. This report describes the survey program and tabulates the data that were collected.
