Geomorphological data for the Lae urban area in Papua New Guinea, focusing on tectonic uplift and earthquake recurrence. The dataset likely contains information on river terrace flights, riser heights, and fault zone structures related to the Ramu-Markham Fault Zone. It was presented at the 2023 Australian Earthquake Engineering Society Conference and is hosted by the Australian Ocean Data Network.
Use Cases
- Model seismic hazard risk for Lae city based on described fault zone structures.
- Estimate earthquake recurrence intervals based on described river terrace flights.
- Analyze tectonic uplift rates based on described terrace riser heights.
- Map active fault traces for urban planning based on the bifurcation of the Ramu-Markham Fault Zone.
Strengths
- Focuses on a high-convergence rate zone (~50 mm/yr) between tectonic plates.
- Describes specific geomorphological features like terrace riser heights on the order of 3 m.
- Results are intended to inform a seismic hazard and risk assessment.
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 data_gov_au.
