Description

Abstract: This dataset is the Earthquake Hazard Risk Contour Map for Australia based on earthquake measurements taken from the Geoscience Australia Earthquake Database. It shows the acceleration coefficient (a) 10 percent chance of being exceeded in the next 50 years. Thus a value of 0.05 as an example means that in any 50 year period, there is a 90% chance that the peak ground acceleration will not exceed 0.05. Where peak ground acceleration is a dimensionless coefficient of acceleration that is used by civil engineers to estimate forces on structures. High values of this calculation represent higher risk areas of earthquake occurrence.

Data quality

Lineage:
This is an interpretive data set based on data derived from GA's World Earthquake Database. Using earthquake locations and measurements from the database, contours reflecting potential earthquake hazard were digitised in Arcinfo for the Australian mainland. In 1997 the 1:1 000 000 scale GA approved coastline was added to the data set and items feature and UFI have been added to complete the quality assurance.

Positional accuracy:
Nominal Scale 1:1,000,000

Attribute accuracy:
High

Logical consistency:
A geoscientist visually inspected the finished dataset to make sure the attributes were accurate and the data were consistent spatially with current scientific information. Tests are also carried out on these data for data completeness, correct spatial representation, attribute accuracy, logical consistency and correctness, and where appropriate for compliance with Geoscience Australia's GIS data dictionary.

Completeness:
The dataset coverage is complete for the whole of continental Australia.
