Evidence from earthquake focal mechanisms and in-situ stress measurements since 1967 indicates substantial horizontal compression across Australia. The dataset includes measurements from eight earthquakes and multiple in-situ sites, such as a 200 km north-south traverse near the 1968 Meckering and 1970 Calingiri earthquakes and sites tested in NSW during 1978 and 1979. It is provided by the Australian Ocean Data Network.
Use Cases
- Model regional stress fields based on earthquake focal mechanism data
- Compare in-situ stress measurements with earthquake-derived stress axes
- Analyze spatial variations in principal stress orientation across different Australian regions
- Validate plate tectonic models against observed high stress values and directions
Strengths
- Includes data from eight earthquakes providing focal mechanism determinations
- Contains in-situ measurements from a 200 km north-south traverse with specific stress values (e.g., 23 MPa and 4 MPa)
- Reports measurements from multiple NSW sites tested during 1978 and 1979
Limitations
- Column-level documentation is absent; field semantics must be inferred after download
- Row count is unknown, which may limit suitability assessment
