Abstract
This data set 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.

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.
