Support gamma phase associator workflows with clear steps and best practices.
Instruction
- Identify the seismic event detection task and the available phase pick data (P-wave and S-wave arrivals).
- Select the appropriate velocity model and association parameters (e.g., time window, spatial constraints) for the target region.
- Run the Gamma phase associator to link discrete seismic picks into cohesive earthquake events.
- Refine the initial event locations and origin times based on the probability distributions of the associated picks.
- Evaluate the quality of the association using residuals, pick counts, and uncertainty metrics.
- Export the associated event catalogs in standard formats for downstream seismological analysis or earthquake monitoring.
When to Use
- When needing to automate the association of seismic phase picks with discrete earthquake events.
- When building earthquake catalogs from dense seismic network data.
- When performing real-time seismic monitoring where high-speed phase association is required.
