The understanding of geotechnical characteristics of the near surface material is of fundamental interest in seismic microzonation for land use planning and designing of new engineering structures.
The unconsolidated materials of young sedimentary basins can have a profound effect on the spatial distribution of earthquake ground motion amplification, resulting in a large variation in the severity of damage to buildings, transportation corridors and other lifeline infrastructures. To be able to carry out a seismic microzonation study for such sedimentary basins a large amount of input data is required on the three dimensional structure of the basin, the stratigraphy of the unconsolidated deposits and their geotechnical and geophysical...
