- Develop methodology to evaluate induced-seismicity hazards
- Statistical modeling of activity in time and space
- Magnitude-recurrence parameters for induced seismicity
- Source model for induced-seismicity in hazard analysis framework
2 – The Evolution of Induced Seismicity
- Develop a quality baseline seismicity catalogue
- Characterize activity rates over time
3 – Characterization of Seismicity Patterns in Alberta
- Improve earthquake locations and magnitudes
- Improve regional velocity model and calibrate algorithms for event location
- Calibrate magnitude algorithms
- Identify areas where seismicity is clustered in time/space
- Determine focal depths from a range of techniques
4 – Ground motion implications of induced seismicity
- Ground-motion prediction equations (GMPEs) suitable for induced events
- Near-distance ground motions and implications of focal depth on GMPEs
5 – Use of enhanced imaging tools to map induced seismicity
- Identify events and source areas not seen with traditional seismic picking methods
- Correlation of brightness function with information on oil and gas activities
- Spectral stacking approaches to enhance signals identified with brightness function
6 – Integration of seismicity and geologic information
- Correlate identified event clusters with geologic structures and energy-related activities
- Coordinated with AGS 3D mapping initiative of subsurface structure and U of C geological images
- Determine factors controlling both natural and induced seismicity
