363 earthquake focal mechanism solutions for southwestern Yukon, estimated using P-wave first-motion polarity data and a probabilistic inversion method. The catalogue was produced by the Government of Yukon and updated on April 17, 2026. It provides constraints on fault behavior, crustal stress, and regional tectonics.
Use Cases
- Analyze crustal stress patterns based on focal mechanism solutions.
- Map fault behavior and tectonic boundaries based on P-axis orientation contrasts.
- Identify unmapped faults based on focal mechanism distributions.
- Validate seismic network coverage improvements based on catalog spatial coverage.
Strengths
- 363 focal mechanism solutions with quantified uncertainties.
- Solutions derived from a probabilistic inversion method.
- Data supports identification of an unmapped fault south of the Duke River fault.
- Catalogue improves spatial coverage for a region with historically sparse seismic network data.
Limitations
- Row count and dataset size are unknown.
- Column-level documentation is absent; field semantics must be inferred after download.
- Data may reflect geographic bias inherent to the Yukon region.
