Lae, Papua New Guinea's second-largest city, sits where a ~50 mm/yr convergence rate between tectonic plates is accommodated. Flights of river terraces, typically with 3-meter risers, imply repeated tectonic uplift events and causative earthquakes greater than magnitude 7. This dataset, presented at the 2023 Australian Earthquake Engineering Society Conference, likely contains geomorphological data to inform seismic hazard assessment.
Use Cases
- Model seismic hazard and risk for Lae city based on described fault zone geometry and terrace heights.
- Estimate earthquake recurrence intervals based on the described method of dating river terraces.
- Analyze the interaction between riverine deposition and tectonic range-building described for the region.
- Map active fault traces for the Ramu-Markham Fault Zone based on the bifurcation pattern described west of Lae.
Strengths
- Focuses on a specific, high-risk urban area (Lae) with a described ~50 mm/yr plate convergence rate.
- Links geomorphological features (3-meter terrace risers) directly to causative earthquake events greater than magnitude 7.
- Describes a clear methodological path for future work to expose active fault traces and extend the study.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Data formats are PDF and HTML, which may not be readily analyzable as structured data.
