23 ambient vibration measurements from sites in Haines Junction, Yukon, collected by the Government of Yukon. The data records microtremor seismic noise used to calculate horizontal-to-vertical spectral ratios and identify resonant frequencies. Preliminary results suggest a spatial trend of fundamental frequency related to proximity to the Dezadeash River basin.
Use Cases
- Map local site amplification hazards based on estimated fundamental frequency (f0)
- Infer shear-wave velocity profiles as a function of depth based on dispersion measurements
- Identify spatial trends in soil stiffness based on the lateral distribution of resonant frequencies
- Characterize seismic hazard in northern regions based on ambient vibration measurements
Strengths
- Data includes measurements from 23 distinct sites
- Provides in-situ estimation of fundamental frequency for site characterization
- Results suggest a spatial trend attributed to proximity to the Dezadeash River basin
Limitations
- Row count is unknown, which may limit suitability assessment
- Column-level documentation is absent; field semantics must be inferred after download
- Description metadata is limited; actual data quality requires manual inspection after download
