2025 USGS Seismic Hazard Model Inputs and Outputs for Puerto Rico and U.S. Virgin Islands

Datasets for the 2025 USGS National Seismic Hazard Model for Puerto Rico and the U.S. Virgin Islands contain model inputs and outputs. Inputs include seismicity catalogs, smoothed seismicity spatial probability density functions, subduction interface fault geometry, and fault-system solutions. Outputs include mean hazard curves, uniform-hazard ground motion data, epistemic uncertainty data, and hazard and risk maps.

Use Cases

• Calibrate earthquake rupture forecasts based on fault-system solutions.
• Generate regional seismic hazard maps based on mean hazard curves and ground motion data.
• Assess epistemic uncertainty in hazard models based on provided uncertainty data.
• Update geologic deformation models based on subduction interface fault geometry parameters.

Strengths

• Datasets are associated with an official U.S. Geological Survey (USGS) National Seismic Hazard Model update.
• Description lists specific model inputs like seismicity catalogs and fault geometry.
• Description lists specific model outputs like hazard curves, ground motion data, and risk maps.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Last update date is unknown; freshness unverified.
