Seismicity Analysis through Point-process Modeling: A Review

  • Y. Ogata


—The occurrence times of earthquakes can be considered to be a point process, and suitable modeling of the conditional intensity function of a point process is useful for the investigation of various statistical features of seismic activity. This manuscript summarizes likelihood based methods of analysis of point processes, and reviews useful models for particular analyses of seismicity. Most of the analyses can be implemented by the computer programs published by the author and collaborators.

Key words: Causal relationship, ETAS model, modified Omori formula, relative quiescence, season ality of seismicity, space-time models.
