Uniform Hazard Spectrum with Distance to Subduction Faults (Phase 1)

This project addresses the limitations of existing seismic attenuation models, which often rely on foreign data and provide only the mean value of spectral accelerations, complicating the definition of values based on reliability and uniform risk levels. The proposal is to develop an improved and more accessible model incorporating key parameters such as fault type, earthquake magnitude, epicentral distance, and the lithological profile of the study site to generate spectral accelerations by degree of reliability. The methodology involves collecting global instrumental earthquakes, generating seismic spectra using specialized software (seismosignal and seismospect), classifying records by soil typology, and developing uniform risk spectrum adjustment equations with different reliability levels using Statgraphics. Data from earthquakes measured in Ecuador will be used to validate the proposed reliability levels. The main impact will be the incorporation of uniform risk design spectra into design codes, promoting the construction of earthquake-resistant structures and reducing vulnerability to collapse.<br/><br/><b>Goal</b>: <br/>The main objective is to develop a uniform risk seismic spectra model applicable to rock and soil, based on the magnitude and distance to active subduction faults, utilizing instrumental earthquake records collected from the global seismological network.<br/><br/><b>Research lines</b>: <br/>Analysis, development and improvement of materials, tools and techniques for use in construction, industry and various applications
