Aplicabilidad de métodos de evaluación de la amenaza sísmica para un proyecto minero (basada en datos neotectónicos, instrumentales e históricos), Andes Centrales, San Juan, Argentina

in the present paper the methodology applied for the evaluation of the seismic hazard in a specific site in the argentinean andes is presented. available neotectonic and seismological information was compiled and analyzed as a preliminary work. as it is usual in most south american regions, background seismological and paleosismological information is scarce and, in general, insufficient to completely define the seismic activity in space and time. the definition of seismic design criteria for all the works involved in the project was done with basis on international practice. both, deterministic and probabilistic analysis methodologies were applied to evaluate the seismic threat in the project's site. the obtained results are compared in this work and the available procedures for selecting the seismic design motions are discussed. finally, a working criterion is defined and the resulting seismic design motions obtained from the study are presented.
