Abstract
The soil profile estimation of Lima, the capital of Peru, is of great importance to adequately design buildings to withstand seismic activity. Particularly, the La Molina district, known for being a rapidly developing urban area, as well as having reported notable damage during past seismic events, has been studied largely. However, these studies have not explored depths greater than 50m. In this study, we intend to estimate soil profiles with depths reaching to the basement rock in La Molina. For this purpose we will apply the joint-inversion technique of dispersion curve and receiver function. The inversion of dispersion curve alone and receiver function alone is initially performed separately. The resulting inverted profiles will be used as a reference for the boundary matrix of the joint-inversion method. Our results have shown that the H/V spectrum obtained with the inverted profile is in good agreement with the observed H/V spectrum obtained with microtremor measurements. Moreover, it is in good agreement with available boring data and Ps logging profile.
