100 earthquakes from the South Australian earthquake catalogue, between 2007 to mid-2015, were selected in an area of the Fleurieu Peninsula with the densest seismograph coverage.

The model consists of an earthquake magnitude map, ranging from near 0.0 to 3.8 near Mount Barker and a 'quake reliability' map showing the error ellipses (2σ) of the hypocentres.

The model includes surface elevation exaggerated 5 times, a super-imposed solid geology map and fault network surfaces. Very little is known of the location of the major faults. The surfaces have been constructed using the mapped surface expression at an angle of 45 degrees in the generally expected dip direction. All the faults have been extended to a depth of 10 km, except the Bremer Fault, which has been extended to 5 km.

The model shows that, contrary to accepted wisdom, the earthquakes do not fall on particular fault planes, but are scattered quite widely. It also shows that the majority occur deeper than 10 km. There is no clear pattern; some areas seem to have many small events, but the largest event seems to be in a volume that otherwise has very few events.
