Earthquake monitoring in the Southwest Seismic Zone, Western Australia

Five new seismic monitoring stations have been added to the Australian National Seismograph Network (ANSN) in Western Australia with the aim of better locating the small earthquakes of the Southwest Seismic Zone of southwest Western Australia. 
The Southwest Seismic Zone, one of the most seismically active onshore areas in Australia, is an area known for its seismicity by the local people who regularly experience small cupboard rattlers. These often occur in swarms as documented by Dent (e.g. 2009, 2014, 2017, 2019, 2020). It is more widely known for the M6.5 Meckering earthquake of 1968 which destroyed many houses in Meckering, produced a 37 km long and 2 m high fault scarp and dramatically bent the railway line. There is no obvious tectonic reason for PREVIEW AUGUST 2021 earthquakes to be occurring in this area as it is in the middle of an Archean cratonic region although the scarps from surface rupturing events, such as the Meckering event, mainly trend approximately north-south and appear to lie along trends in the magnetic data (Dentith et al 2009). 
Until mid-2020 the ANSN had a fairly sparse coverage of the area. A secondary Public Seismic Network (PSN) is also monitoring in the area. Inclusion of the PSN data has quite an effect on the calculated locations, as exampled by the tighter clustering of the Beacon swarm of 2009 (Dent, 2009) rather than the linear trend from just using the ANSN data. 
In mid-2020 four more semi-permanent stations were installed in the area and one in the Goldfields and added to the data streaming into the National Earthquake Alerts Centre (NEAC) and incorporated into the location algorithm. This presentation looks at seismicity of the area, the small swarms that have been detected since then and the relationship of the seismicity to the geology.

Potential geologic sources of seismic hazard in the Sydney Basin: proceedings volume of a one day workshop, April 2005

The Sydney Basin encloses a significant proportion of the Australian population, and the 1989 M5.6 Newcastle earthquake demonstrated that the basin is not immune from the impact of even relatively modest earthquakes.  In spite of this, few investigations have been conducted to identify and characterise potential geologic sources of strong ground shaking.  A recent major study of the southern part of the basin commented that

The available data are less complete than ideal for the purposes of probabilistic seismic hazard analysis.
Essentially, the extreme infrequency of large earthquake events in intraplate regions, such as Australia, means that the short historic record of seismicity is poorly suited to the task of assessing seismic hazard.  

Hence, geologic, geomorphic and paleoseismic knowledge has a vital role to play in obtaining constraint on the probable location and recurrence of large and damaging earthquakes near Sydney.
In April 2005 a one day workshop at the University of Sydney brought together a diverse range of researchers with experience in the geology and geomorphology of the Sydney Basin, neotectonics and seismic hazard science.  A series of seminars were presented covering geology, geomorphology, seismicity and seismic hazard.  These served as a nucleation point for subsequent discussion, and the drafting of the papers presented herein.  
This proceedings volume contains within its covers tools for understanding large earthquake occurrence within the Sydney Basin and compiles 12 papers addressing landscape and structural developement, and seismic hazard aspects, of the Lapstone Structural Complex west of Sydney.
Hence, it represents a framework upon which future advances in our understanding of the seismic hazard posed to Australia's largest population centre may be based.

Establish Brennock Park-Kallista Gravity (P195491), gravity point data

Gravity data measures small changes in gravity due to changes in the density of rocks beneath the Earth's surface. The data collected are processed via standard methods to ensure the response recorded is that due only to the rocks in the ground. The results produce datasets that can be interpreted to reveal the geological structure of the sub-surface. The processed data is checked for quality by GA geophysicists to ensure that the final data released by GA are fit-for-purpose.
 This Establish Brennock Park-Kallista Gravity (P195491) contains a total of 1 point data values acquired at a spacing of None metres. The data is located in VIC and were acquired in 1954, under project No. 195491 for None.

AUSGeoid98 v.1.0 data files: Mount Anderson (se51-11)

AUSGeoid98 data files contain a 2 minute grid of AUSGeoid98 data covering the Australian region, which you can use to interpolate geoid-ellipsoid separations for the positions required.You can use your own interpolation software, or you can use Geoscience Australia's Windows Interpolation software (Winter). The data files are text files in a standard format that cover the same area as standard topographic map areas. Files covering both 1:250,000 (approximately 100 x 150 km) and 1:1,000,000 (approximately 400 x 600 km) map areas are available. There is a 4 minute overlap on all sides of each area. Data format: AUSGeoid98 data files have a header record at the start of each file, to distinguish them from the superseded AUSGeoid93 data files. AUSGeoid98 data files show the geoid-ellipsoid separation to 3 decimal places, while the superseded AUSGeoid93 data files showed only 2 decimal places. AUSGeoid98 deflections of the vertical were computed from the geoid-ellipsoid separation surface, while the AUSGeoid93 deflections of the vertical were computed from OSU91A.

The data collected are processed via standard methods to ensure the response recorded is that due only to the rocks in the ground. The results produce datasets that can be interpreted to reveal the geological structure of the sub-surface. The processed data is checked for quality by GA geophysicists to ensure that the final data released by GA are fit-for-purpose.
 This Clarence-Richmond Coastal Area, NSW, 1996 (P643), radiometric line data, AWAGS levelled were acquired in 1996 by the NSW Government, and consisted of 48370 line-kilometres of data at a line spacing between 200m and 1600m, and 80m terrain clearance. To constrain long wavelengths in the data, an independent data set, the Australia-wide Airborne Geophysical Survey (AWAGS) airborne magnetic data, was used to control the base levels of the survey data. This survey data is essentially levelled to AWAGS.
