The Snowy Monaro region of NSW hosts infrastructure critical to Australia’s water and energy security. The region also contains several neotectonic features that show evidence for earthquake activity since the current crustal stress regime has been in place, and therefore have the potential to produce large future earthquakes. Here, we present detailed structural and geomorphic evidence from 2 m resolution lidar digital elevation models, geological maps and geophysical data for surface-rupturing neotectonic features in the region. We improve the accuracy and precision of the mapping of known features and identify evidence for five previously unmapped features. The evidence collected is characterised using classification schemes and each neotectonic feature is assigned a confidence level ranging from A (Definite neotectonic feature) to D (Unlikely to be a neotectonic feature). Maximum moment magnitude (Mw,max) estimates for single-fault, and segmented rupture scenarios are presented. Our data will inform national-scale and infrastructure-focussed seismic hazard analyses.
