The strong ground motion resulting from a major earthquake determines the level of the seismic hazard to enable earthquake engineers to assess the structural performance and the consecutive risks to the property and life, as well as providing detailed information to seismologists about its source mechanism. From the earthquake engineering point the main problem is the specification of a design level ground motion for a given source-site-structure-economic life and risk combination through deterministic and probabilistic approaches. In seismology the strong motion data provide the high frequency information to determine the rupture process and the complexity of the source mechanism. The effects of the propagation path on the strong ground motion is a research area receiving sub stantial attenuation both from earthquake engineers and seismologists. The Institute provided a venue for the treatment of the subject matter by a series of lectures on earthquake source models and near field theories; effects of propagation paths and site conditions, numerical and empirical methods for prediction; data acquisition and analysis; hazard assessment and engineering application. The book is organized in five sections. The first section on the Earthquake Source begins with a general paper on strong motion seismology, followed by treatments on earthquake source mechanisms with several case studies. The assessment of strong ground motion for engineering design relies both on empirical and theoretical methods. These methods are covered in the second section on the Prediction of Strong Ground Motion in a series of papers dealing with source and propagating path parameters, attenuation and scattering effects and numerical simulation procedures. The third section titled Acquisition and Interpretation of Strong Motion Data encompasses the steps for the acquisition and processing of the strong motion data with particular emphasis on network management and analog-to-digital conversion. Papers on case studies dealing with strong ground motion data analysis and seismic intensity assessments in several parts of the world complement the theoretical treatment. Probabilistic models for the assessment of Strong Ground Motion based on point process to describe its occurrence in space, time and size, and based on a continuous time-dependent process to describe its var~tion for a given occurence are covered under the fourth section on Hazard Assessment. The importance of the geologic and tectonic environment in occurence models are amplified in another vii viii PREFACE paper in the same section. Fifth section is devoted to the site response and £ngineering analysis. Determination of the site response for a given seismic environment is an important engineering problem not only for the design of structures but also for the proper interpretation of strong motion records obtained at the building foundation. Both issues are treated in depth with complementing material on the constitutive relationship for soils and on the observational data on local site effects on strong ground motion. The last paper in this section of the book deals with the engineering uses of strong motion data providing a venue for the earthquake resistant design of structures. Strong ground motion, a problem of mutual interest to earthquake engineers and seismologists, can be ideally studied through interaction between both disciplines. The editors would be happy if this publication imparts small momentum to this communication.
