This is a stochastic point process incorporating the empirically observed characteristics of stress triggered activity: its main peculiarity is that each earth-quake has some magnitude-dependent ability to trigger its own Omori law type aftershocks. In particular the .

This observation is the basis for the deterministic time-predictable recurrence model of Shimazaki and Nakata. Using the basic assumptions of the time-predictable recurrence model, we develop a stochastic model of earthquake occurrence that incorporates temporal dependence.

The role of stochastic models in geophysics is discussed from both an historical and a philosophical point of view. Specific models for earthquake sequences are analysed in the light of these general considerations, and some related developments in this general area are by: Although the stochastic wave model considered in this work is stationary and homogeneous, it is a straightforward task to extend the methodology introduced to nonstationary and l or non-homogeneous stochastic waves characterized by an evolutionary power by: 5.

Poisson processes and extensions. Introduction. Poisson processes are one of the simplest and most applied types of stochastic processes.

They can be used to model the occurrences (and counts) of rare events in time and/or space, when they are not affected by past history. In the use of historical earthquake catalogs for seismic hazard, the main objective is to estimate the rate of earthquakes of various sizes in a region around the site of interest.

(), “A Clustering Model for Earthquake Occurrences,” Bulletin of the Seismological Society of America Vol. 60, No. 6 Cited by: In their study, the ETAS model parameters were fixed to those obtained by fitting a stationary ETAS model to the earthquake catalog corresponding to a wider region around the study area.

Often, such pre-determination of model parameters may not be feasible because the seismicity is localized (e.g., reservoir associated seismicity) or the model Cited by: 1.

[58] Using the reconstruction techniques introduced by this paper, we analyzed the clustering features of earthquake occurrences. Even though the reconstruction is based on the ETAS model, we find several discrepancies of earthquake clustering from the model assumptions, as outlined below.

[4] Because these probabilities are estimated through a particular model, the closeness between the formulation of the model and the reality is the essentially important factor influencing the output.
