Abstract
On 22 December 1987 a shallow magnitude 4.9 earthquake occurred in western Victoria where there is no record of previous seismic activity. It was felt over a remarkably wide area of Victoria and South Australia and caused minor damage in the epicentral area. There were no foreshocks and only ten aftershocks were recorded on the nearest seismograph, near Willalooka in South Australia. All ten occurred within five days of the mainshock. The earthquake occurred in a seismic zone that extends over a 500 km wide belt along the entire eastern coast of Australia linking the Southeast Seismic Zone of South Australia with the Eastern Highlands Zone through Queensland, New South Wales, Victoria and Tasmania. Its focal mechanism, a thrust with a principal stress directed east-west, is typical of earthquakes in the Lachlan Fold Belt.
