This website contains information on faults, folds and other features within Australia that are demonstrated or suspected to relate to the occurrence of large earthquakes during the period that the current crustal stress field has pertained (i.e., the past 5–10 million years). Records of neotectonic features include, where available, detailed descriptions and bibliographic references. Read our factsheet for further information.
This dataset forms the basis for the fault source model (FSM) used in the National Seismic Hazard Assessment 2018 (NSHA18), which is described here: http://pid.geoscience.gov.au/dataset/ga/100382, and can be accessed here (NSHA18 version, last updated March 2017): https://github.com/GeoscienceAustralia/NSHA2018/tree/master/source_models/faults/FSM.
For enquiries regarding neotectonic features please contact us through earthquakes@ga.gov.au.
