Tacna city in Peru is located within the area that includes the ring of fire of the Pacific, a zone of high seismic activity. According to the seismic history, there were earthquakes in the last five hundred years that caused the total destruction of the city on more than one occasion, such as the earthquake of 1868 that had a magnitude of Mw=9.0 and an intensity of X MMI (Modified Mercalli lntensity Scale): The last majar seismic event was the earthquake of June 23, 2001 of Mw=8.4, which showed that the most damage occurred in the districts of Ciudad Nueva and Alto de la Alianza, classified as intermediate soils with strata of loase sand. In this research, the records of six accelerograph stations from Tacna city, were analyzed to obtain the response spectra and compare them with the spectra obtained in the site response analysis, in arder to obtain the predominant amplifications and frequencies of the soil and structure. The results show that the values of the soil amplifications in Tacna, vary from 1.3 to 1.6; 0.34 s is the characteristic period of vibration for the intermediate soils and 0.10 s to 0.30 s for the rigid soils. The spectra of elastic accelerations show that the values of the amplification coefficients vary from 3.2 to 3.5. These results are superior to those proposed by the Peruvian Seismic Design Standard E.030.
