Map of the CURNAMONA seismic array

As part of a wider AuScope project aiming at densifying the seimic coverage in Australia, 34 short-period (Lennartz 3D-Lite MkII) seismometers were deployed across the Curnamona Craton and the Adelaide Rift Complex in South Australia. The arrays covers an area of 100 000 km 2 with a station spacing of approximately 60 km. It extends from the Spencer Gulf in the east to the New South Wales border in the west, and runs from the Strzelecki Desert in the north to Danggali nature reserve in the south.

From April to November 2009, the instruments continuously recorded surface displacements in three directions (North, East and vertical components) at a sampling rate of 25 Hz from both local and distant earthquakes. The region is of particular interest for the supply of geothermal energy, with many ongoing industry projects in the area. This area is also seismically active and local earthquake data recorded on this array will help improve our ability to locate and characterize these events. The seismic data collected can also help to image the structure of the lithosphere and the upper mantle with a finer resolution in this complex geological setting.
