Government of Yukon researchers relocated over 5,000 earthquakes between 2010 and 2021 in southeastern Alaska and southwestern Yukon. The work utilized improved seismic networks to quantify the seismogenic layer thickness and map active faults, including the Totschunda-Fairweather 'Connector' and newly identified faults. The dataset supports a hypothesis of deformation occurring on a well-defined network of shallow faults.
Use Cases
- Mapping active fault networks based on relocated earthquake positions
- Quantifying seismogenic layer thickness based on improved depth uncertainty reductions
- Estimating and classifying fault motion based on combined earthquake relocations and focal-mechanism data
- Analyzing regional transpressional regimes and slip partitioning based on seismic observations
Strengths
- Over 5,000 earthquake events relocated
- Data spans 11 years from 2010 to 2021
- Utilizes improved regional broadband seismometer networks for enhanced accuracy
Limitations
- Column-level documentation is absent; field semantics must be inferred after download
- Row count is unknown, which may limit suitability assessment
