Aims and Scope

The 4th ESG International Symposium will address current issues in earthquake ground motion prediction with an emphasis on the effects of surface geology on seismic motion. ESG4 will present recent studies, with an emphasis on advances in research since 2006 and data obtained from recent significant earthquakes, and will help to guide future research on the effects of surface geology on seismic motion.
