RESEARCH AREAS

• Verification seismology

     Digital signal processing:

               development of secondary phase detectors (Lg, Rg);

               development of improved pre-filtering and analysis methods for phase identification using array processing.

     Collection, analysis and interpretation of data from seismic arrays and networks for nuclear monitoring and Earth structure studies.

     Event location and discrimination.
