The paper is dedicated to the classical glissade’s modeling in order to explain the earthquake mechanisms. The B&K model has been rethought generalizing the uniform movement of the largest stratum, corresponds to any continually acting force. In addition, for the resistance function has been used an expression obtained by the authors, based on the Elementary Catastrophes Theory that fully satisfies the conditions of the existence and uniqueness theorem regarding the solutions of the systems of ODE. The generalized B&K model equations have been solved numerically for a particular case through the respective standard software package MATLAB. The analysis of the results highlights a periodicity at the seismic activity (obtained at constant force) and the earthquake’s appearances it is shown as a consequence of the different system’s resonance points. All of the above would allow through the reengineering methods obtaining valuable information related to the structure and behavior of local plates.

In the mid-sixties of the 20th century, a seismicity one-dimensional model, based on a spring system with friction, was presented by the two authors mentioned in the title. Through this model was studied the viscosity behaviour involved in the stratums mutual displacement. However, in the analysis pertinent to the occasion, seeing the fig.13 ibid it can be observed an error related to the viscosity function (low speeds’) limits, which determines its “performance” during the time - lapse of the stratums breaking. From the height of the present knowledge, using the Elementary Catastrophes Theory developed in later times by René Thom and Zeeman, we have reached certain conclusions which, although do not refute the results of said article, they can significantly improve some aspects of the model and in general of the earthquakes physics.
