caving due to this particular situation, generating decompression over the P.I. and allowing
further unfavorable deformational states. The northern area labeled as vulnerable in this
production sector is reasonable to be assumed as an extension of the collapsed area ahead
of the caving front in the northern section of Esmeralda, formerly fed to the model as a
training subset. This region is characterized by a high frequency of seismic events, thus
