Abstract

The dynamic characteristics of the ground in Lima, capital of Peru, specifically the amplification are investigated. By using the small and large microtremor array measurements we estimated the soil velocity profiles with depths to the bedrock in many cases. These profiles were used to estimate the amplification factors. Important results are the large amplification factors at EMO, VSV, CAL and CMA (La Molina, Villa El Salvador, El Callao and Bellavista district, respectively).
