Probabilistic and statistical methods are finding wider application in Seismic Risk Analysis. Seismic Risk Analysis is a method of determining design levels of seismically induced ground-motion by quantitative expression of uncertainties in Seismological, Geological, and Geophysical parameters. An expression of Seismic Risk requires three factors: A designated amplitude of ground motion, a chosen design lifetime and an associated risk (probability that the ground-motion amplitude will be exceeded). By using all available geological, tectonic and seismic data in Peru, the seismic sources and their associated parameters (recurrence relationships through the B value, location of the earthquakes, the rate of occurrence of events, the low and upper bound magnitudes) and the attenuation of the ground-motion which is a parameter of Interest from the source to the site (in terms of acceleration, velocity and displacement) have been determined. The evaluation of Seismic Risk of Peru has then been made through application of the "total probability theorem" by means of existing computer programs. Probabilistic Maps in terms of acceleration, velocity and displacement have been obtained for Peru and a preliminar proposal of zoning of Peru is presented. Also is presented a discussion about uncertainties in the Seismic Risk Analysis. キーワード（英）： - 記事区分： - 区分 　　　委員会論文集
