Ridgefield seismology

Further Information

The UWA Future Farm 2050 is located in the Southwest Seismic Zone, Australia’s most active seismic region.

The Ridgefield seismograph is part of an Australia-wide network of budget-priced seismographs operated by enthusiasts, with the assistance of the Australian Centre for Geomechanics (ACG), based at UWA. The data from this network is used by Geoscience Australia to improve the precision of the earthquake locations, as well as to detect new, small events.

A seismic recorder was installed at Ridgefield in early 2012.

The recorders form part of an informal world-wide Public Seismograph Network (PSN) that uses analogue-to-digital converters and associated software marketed by a Californian-based seismologist, Larry Cochrane.

This basic system has been made vastly more useful by communications software, written specifically for the ACG, that allows the data collected to be posted to a specially developed website, where it can be viewed and analysed within an hour of its collection.

The Ridgefield seismograph is part of a fairly dense network of PSN stations in the wheatbelt region of WA, located in the Southwest Seismic Zone. The data from this network is allowing us to improve the precision of the earthquake locations made by Geoscience Australia, as well as to detect new, small events that are currently below their detection limit threshold.
