    In the present research, a deterministic spectrum was calculated and obtained for this sector, which was compared with the response spectrum of the NEC-SE-DS2015. In addition, using this deterministic spectrum and the Etabs 16.1.2 software the vibration period, for three structures located in the study´s area was calculated. For this, the following steps were taken: Identify the tectonic regime in the study area. Select the geological faults with greater length and those closest to the study´s area, such as: Corticals (Ambato, Huachi and Totoras), and Subduction (Nazca). Through the standard penetration test (SPT), was calculated the average speed of the shear wave Vs30. Using the empirical correlation with the uncorrected standard penetration resistance (N) and the average speed of the shear wave (Vs30), the moment magnitude for each selected fault was calculated. Then, based on the Wells - Coppersmith methodology that mentions that when using parameters such as the distance to the epicenter, hypocenter and focal depth in conjunction with the Ground Movement Prediction Equations (GMPEs), acceleration spectra are obtained, the same as finally, by means of an envelope of maximum accelerations, the deterministic spectrum is obtained, which is compared with the response spectrum of the NEC-SE-DS-15. The accelerations of the deterministic spectrum for buildings that have periods between 0.10s to 0.30s (1 to 3 floors) exceed the NEC-SE-DS-15 spectrum, which means that these structures present a higher degree of risk.
