Calculate the total Earthquakes Force and Coefficients ARMA

Abstract

This study discusses the use of ARMA coefficient models. We know that for any random time series, we can write the ARMA(p,q) model detailed by Box and Jenkins. We can implement this using ARMA models, which have proven effective in many procedures, such as earthquakes and acceleration time series generated by random models Within the frequency time limits. provided comprehensive reviews of As a model of acceleration time series in both the frequency and time domains. Several research papers have addressed ARMA models. Box and Jenkins discussed ARMA models in detail  .Here, we found the earthquake amplitude in terms of the ARMA(p,q) coefficients, but the ARMA(2,2) model can be considered the most appropriate in this case for the regions of northern Algeria, from which we extracted the Aïn Defla, Casablanca, and Affroun earthquakes. Taking into account the AIC RITERIA criterion, we found that it is in fact ARMA(2,2), which is what we studied. Using mathematical relationships, including some results such as the relationship used in calculating the seismic magnitude, we find that it agrees with the model.ARMA(2.2)
