The PTS is actively pursuing initiatives to improve the performance of the IDC waveform automatic processing pipeline. Some active research and development areas are: 

  • Further development of an integrated waveform quality control module and its application in all stages of the automatic processing pipeline;
  • Evaluating the new methods that can improve the pipeline performance in processing aftershock sequences and recurring events;
  • Evaluating and integrating new detectors and associators into the IDC processing pipeline;
  • Tuning components of IDC pipeline processing in order to optimize their performance; 
  • Advances in event screening. 
  • Evaluating global seismic and/or hydro-acoustic three-dimensional travel time models and optimizing location capabilities. 

The PTS is initiating procedures for issuing the Updated Event Bulleting (UEB) and a State Requested Method Report (SRMR) as part of Special Studies and Expert Technical Analysis.  The status of this work will be reviewed. A prototype tool will be discussed with a view of eliciting expert input on algorithms and methodologies to incorporate. 

The objective of this technical expert meeting is twofold:

  1. The first two days of the meeting will be dedicated to exploring advances to waveform processing that may improve the IDC waveform pipeline processing, including tools and methodologies for testing and validation; 
  2. The third day of the meeting will be dedicated to discussing waveform Special Studies and Expert Technical Analysis - methods, use of data and content of UEB and SRMR. 

Meeting participants are welcome to contribute to the technical meeting by making a 15 minute presentation related to one of the topics above. 

To be determined. 

Experts from NDCs and research establishments that are involved in testing, applying and developing waveform methods that may be suitable for inclusion into the IDC waveform automatic processing pipeline, or may be applicable to Special Studies and Expert Technical Analysis. 

Applicants are requested to visit our website Opens external link in new and apply online latest by 3 June 2019.
