Neotectonic Faults in Gippsland, Australia, Mapped with Lidar Data

26 identified neotectonic features in the Gippsland region of southeastern Australia, characterized by high seismic activity. The dataset, presented at the 2025 AEES conference, uses Vicmap lidar data to improve fault mapping and documentation for seismic hazard assessment. Results inform estimates of uplift rates and maximum-magnitude earthquakes to improve community safety and energy security.

Use Cases

• Conduct probabilistic fault displacement hazard assessments based on updated neotectonic linework.
• Plan locations for future paleoseismic trenching studies based on improved fault mapping.
• Estimate uplift rates and maximum-magnitude earthquakes for identified seismogenic faults.
• Inform regional energy infrastructure planning and community safety actions based on seismic hazard characterization.

Strengths

• Focuses on a region with 26 identified neotectonic features capable of generating earthquakes greater than Moment Magnitude 6.
• Incorporates recently available Vicmap light detection and ranging (lidar) data to improve mapping accuracy.
• Results were presented at the 2025 Australian Earthquake Engineering Society National Conference, indicating peer review.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to the Gippsland region study area.
