5536 seismic events above magnitude 1.5 from 2010–2021 were relocated using double-difference methods applied to the USGS catalogue. The Government of Yukon produced this catalogue, which demonstrates improved spatial resolution and reduced location uncertainties. The relocated events reveal new fault connections, such as between the Totschunda and Denali faults.
Use Cases
- Analyze seismicity patterns based on relocated event coordinates and depths
- Map fault connections based on the interpreted new faults from relocated events
- Study crustal deformation based on events constrained to the uppermost 10 km of the crust
- Validate seismic models based on reduced travel time residuals and location uncertainties
Strengths
- 5536 seismic events provide a substantial sample for analysis
- Location uncertainties are quantified as 1.2–2.4 km horizontally and 1.5–2.1 km vertically
- Catalogue spans 11 years (2010–2021) for temporal trend analysis
Limitations
- Column-level documentation is absent; field semantics must be inferred after download
- Row count is known, but specific data format and internal structure details are unknown
