Variability of soil response across a local area of interest is a result of the variability of the local geological and geotechnical conditions. These conditions in the Boston area were modeled through the collection and input of publicly available soil columns into a database. Geotechnical properties were obtained from recent Central Artery/Tunnel Project geotechnical reports. One-dimensional soil response analyses using the geological and geotechnical parameters were performed for 155 locations throughout the area. Input ground motions used in the analyses included a high-frequency and a low-frequency seismogram, both of the same duration. The amplification ratios at selected structural periods (PGA, 0.2, 0.3, and 1.0 seconds) were kriged to create maps showing spatial variability and range of amplification in the Boston area. These maps serve to show those areas of increased local ground shaking hazard in the Boston area.*
