In order to create a soil amplification map for Lima, Peru, parameters that correlate best with amplification are examined. Shallow shear wave velocity profiles estimated from MASW measurements at 105 sites were used to provide amplification factor AvTF. AVs10 seems to be the best value for estimating amplification in Lima from the data available. We have attempted to create AVs10 map correlating three parameters – elevation, H/V peak period, and soil type. From this AVs10 map, we have estimated an amplification map for Lima.
