    The purpose of this research project is to calculate the period of vibration of three type structures located in the study area, also to obtain a deterministic spectrum for this sector expressed as the acceleration of gravity Sa (g), to compare it with the response spectrum of the NEC 2015. For this process, the following steps were carried out: Identify the tectonic regime in the study area, select the seismic sources (geological faults) with the longest length and the closest ones capable of producing a significant movement that affect the study site, such as Ambato, Huachi, Totoras, Samanga and Subduction failure fail. By means of the standard penetration test (SPT) the average speed of the shear wave Vs30 approximate for the type of profile was calculated using an empirical correlation between the uncorrected standard penetration resistance (N) and the shear wave velocity (Vs). The magnitude of momentum for each selected fault was calculated, based on the Wells-Coppersmith methodology, using parameters such as the distance to the epicenter, hypocenter and focal depth. Through the Soil Movement Prediction Equations (GMPEs) you get acceleration spectra and through an envelope of all spectra of maximum acceleration the deterministic spectrum is achieved, which is compared with the response spectrum of the NEC 2015. The accelerations given by the deterministic spectrum for buildings that have structural periods between 0.10s to 0.60s are greater than the spectrum of the NEC 2015, which means that structures with 1 to 5 floors have a higher degree of risk.
