Microtremor Analysis To Calculate Shear Waves Velocity Profiles Using the Spatial Autocorrelation Method (Spac) in Armenia, Colombia
Abstract eng: An analysis of microtremors records was performed to determine shear-wave velocity profiles by using linear arrays of seismograph and accelerograph stations and based on the Spatial Auto Correlation Method – SPAC. Five linear arrays with three hours duration for each distribution were deployed on site Puerto Espejo in Armenia city. By means of an inversion procedure velocity profiles were determined for shear waves from the autocorrelation and dispersion curves. For the arrays a profile up to 400 m composed of three layers with velocities in the range 110 m/s – 800 m/s was obtained and coincide with downhole studies in first 30 meters.
