Shear-wave velocity models derived from horizontal-to-vertical spectral ratio measurements at nine temporary broadband seismometer sites near Burwash Landing, Yukon. The Government of Yukon produced these models to constrain layering and structure within shallow sediments and bedrock up to 500 meters depth. The dataset was last updated on April 17, 2026.
Use Cases
- Estimate sedimentary cover thickness over bedrock based on shear-wave velocity models.
- Map depth to bedrock and discontinuities within bedrock for geological modeling.
- Analyze spatial variation in bedrock depth relative to the Denali fault for tectonic studies.
- Construct geothermal resource development models based on refined crustal structure insights.
Strengths
- Models are derived from nine broadband seismometer sites, providing multiple measurement points.
- Results constrain layering and structure for the upper 500 meters of the crust.
- Bedrock depth estimates are provided, varying from 50 to 450 meters.
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 specific study area near Burwash Landing.
