Commission on Seismological Observation and Interpretation (CoSOI)

Scope

The essence of seismology lies in the observation and interpretation of earthquakes and earthquake-generated ground motions, together with effective data distribution and analysis. There is a continuing need to improve mechanisms for the archiving, dissemination and analysis of these data.

The real Earth structure varies in three-dimensions, can show variation with time and is anisotropic and anelastic in part. Thus methods for seismogram interpretation need to take account of the complexities, which are revealed in the currently available high quality data.

Topics of current interest to the Commission include:
