Seismic Phase Picker

caution

Module currently in development.

The Seismic Phase Picker is a neural-network picker that detects earthquake P-waves at Grillo sensors. The picker was created by retraining PhaseNet network on Grillo Sensor data from a Mexican network deployment.

It creates Pick and Amplitude objects that are passed to subsequent modules, such as those for seismic association, location and magnitude estimation.

Configuration​

Detector

  • Max window [float]: Maximum time window after now after which new detections are declared
  • ML thresh [float]: Threshold for phase detection
  • No Det Win [float, seconds]: Time since a detection after which no more detections are going to be issued
  • Verbose [boolean]: Logs are printed in when set to true
