The design and location of civil engineering structures at a project site require, aside from investigation of the site geology and geotechnical field and laboratory tests, knowledge of the soil-column shear-wave velocities and the geometry of the layers within the soil column and that of the soil-bedrock interface. We shall present case studies for seismic, geotechnical, and earthquake engineering site characterization.

The narrow scope of engineering seismology includes its application to geotechnical site investigations for buildings and engineering infrastructures, such as dams, levees, bridges, and tunnels, and landslide and active-fault investigations. It also includes seismic microzonation to determine soil amplification and liquefaction susceptibility within a municipal area to estimate the earthquake risk. The broad scope of engineering seismology also includes its application to groundwater exploration, coal and mineral exploration, geothermal exploration, and investigations of historic buildings and archaeological sites. This book primarily is devoted to application of the seismic method to geotechnical engineering. Nevertheless, the book also includes chapters on case studies for the broader scope of engineering seismology.
