Uniform Hazard Spectrum with Distance to Subduction Faults (Phase 2)

This research project addresses the need to develop a more practical and comprehensive seismic attenuation model than existing ones, which predicts uniform hazard spectra instead of just the mean value. The core problem is that current models often require parameters that are difficult to quantify, such as precise fault geometry. The proposed solution is the development of a new, easy-to-use model that incorporates key parameters like shear wave velocity, lithological profile typing, epicentral distance, and the desired reliability level for reverse faults in subduction zones. The methodology involves collecting instrumental earthquakes from international databases (PEER and NIED), generating seismic spectra using Seismosignal software, classifying data by soil typology, and developing uniform hazard spectrum adjustment equations using Matlab. The model will ultimately be validated by comparing its results against instrumental records from the 2016 Ecuador earthquake. The expected impact is the incorporation of these uniform hazard design spectra into seismic design codes to enhance structural resilience and prevent collapse.<br/><br/><b>Goal</b>: <br/>The primary objective is to develop a uniform hazard seismic spectra model applicable to rock and soil conditions, based on the distance to active subduction faults, utilizing instrumental earthquake data collected from the global seismological network.<br/><br/><b>Research lines</b>: <br/>Evaluation and development of methodologies related to the interaction between the environment and civil works, based on geoscience
