Introduction to Earthquake Site Response deals with the said subject in its totality. Intense ground shaking during large earthquakes can damage or even cause failure of engineered structures such as buildings, bridges, highways, and dams. Sustained strong shaking can also trigger ground failures, such as rock falls, landslides, earth flows and liquefaction. Strong motion seismology uses special sensors, called accelerometers, to record these large-amplitude ground motions and the response of engineered structures to these motions. Recordings of large-amplitude seismic waves near the earthquake source can be used to investigate the fault motions that produced the earthquake. Site response and ground motion studies use standard seismometers and oil-industry standard geophones to measure the local shaking from natural and man-made sources. These measurements help predict differential, site-dependent ground motion resulting from earthquakes. This information is used to upgrade building codes, to design earthquake resistant structures, and to predict the patterns of strong shaking from future large earthquakes. This book will be of immense help to all those contemplating to acquire an expert knowledge of geotechnical Earthquake Engineering & Seismology.
