A UNESCO Intergovernmental Oceanographic Commission workshop report synthesizes findings from a 2018 expert meeting in Wellington, New Zealand. Fourteen experts from four countries identified and ranked worst-case seismic scenarios for the Tonga-Kermadec trench. The report discusses gaps in scientific knowledge, instrumentation, and tsunami readiness for at-risk populations.
Use Cases
- Assessing tsunami risk to coastal communities based on identified seismic scenarios.
- Evaluating gaps in seismic and tsunami instrumentation for the Tonga-Kermadec trench.
- Planning tsunami warning system improvements based on expert recommendations.
- Studying tectonic uncertainty in subduction zones for hazard modeling.
Strengths
- Report synthesizes findings from a workshop of fourteen international experts.
- Identifies specific seismic scenarios ranked by probability (low, medium, high).
- Focuses on a specific geographic region: the Tonga-Kermadec trench.
Limitations
- Description metadata is limited; actual data quality requires manual inspection after download.
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
