Abstract

The 14 papers of the session may be divided (somewhat artificially, of course) in three main subgroups: - a significant number (5) deal with the whole process of predicting strong ground motion for design, starting from geological / tectonic considerations and ending at a quantitative estimate of some ground motion parameters (peak acceleration, response spectrum,. .. ), either on a regional or national scale for zoning purposes (9.17, 9.24), or at a specific site for the design of some specific structures (papers 9.10, 9.13), or finally from a methodological point of view ( 9.13, 9.24, 9.26). - the 7 papers in the second sub-group each focus on one particular aspect of earthquake hazard estimation. Paper 9.2 is concerned with the estimation of the static deformations induced by strike slip events. Paper 9.3 focus on the contribution of Love waves in low frequency motion. Paper 9.4 investigates the relationship between epicentral intensity and magnitude for a better use of historical seismicity. Paper 9.5 presents the main characteristics and interests for both scientific and engineering purposes, of a new, large set of high quality digital strong motion data. Papers 9.6 and 9.25 focus on site effects, and even more particularly on the geotechnical characterization of sites for microzoning purposes. Finally, paper 9.19 draws attention on the importance of the orientation of underground geological structures with respect to the epicentral direction on the effective damage to be expected at a given site. - the 2 remaining papers (9.20, 9.21) present very interesting cases on well documented and surveyed induced seismicity under large size dams in regions of otherwise weak natural seismicity (central-western Thailand). These 14 papers are briefly summarized, and their conclusions shortly discussed, in the following three sections, while the fourth one, as a conclusion, lists the main outcomes and issues raised by this series of papers.

General Report Session 9: Seismology: Predicting Strong Ground Motion for Design

St. Louis, Missouri

The 14 papers of the session may be divided (somewhat artificially, of course) in three main subgroups: - a significant number (5) deal with the whole process of predicting strong ground motion for design, starting from geological / tectonic considerations and ending at a quantitative estimate of some ground motion parameters (peak acceleration, response spectrum,. .. ), either on a regional or national scale for zoning purposes (9.17, 9.24), or at a specific site for the design of some specific structures (papers 9.10, 9.13), or finally from a methodological point of view ( 9.13, 9.24, 9.26). - the 7 papers in the second sub-group each focus on one particular aspect of earthquake hazard estimation. Paper 9.2 is concerned with the estimation of the static deformations induced by strike slip events. Paper 9.3 focus on the contribution of Love waves in low frequency motion. Paper 9.4 investigates the relationship between epicentral intensity and magnitude for a better use of historical seismicity. Paper 9.5 presents the main characteristics and interests for both scientific and engineering purposes, of a new, large set of high quality digital strong motion data. Papers 9.6 and 9.25 focus on site effects, and even more particularly on the geotechnical characterization of sites for microzoning purposes. Finally, paper 9.19 draws attention on the importance of the orientation of underground geological structures with respect to the epicentral direction on the effective damage to be expected at a given site. - the 2 remaining papers (9.20, 9.21) present very interesting cases on well documented and surveyed induced seismicity under large size dams in regions of otherwise weak natural seismicity (central-western Thailand).
