Exciting news! We're transitioning to the Statewide California Earthquake Center. Our new website is under construction, but we'll continue using this website for SCEC business in the meantime. We're also archiving the Southern Center site to preserve its rich history. A new and improved platform is coming soon!

Earthquake Ground-Motion Amplification in Southern California

Edward H. Field

Published 2001, SCEC Contribution #584

The two most important factors influencing the level of earthquake ground motion at a site are the magnitude and distance of the earthquake. The map available here shows the influence of a third important factor, the site effect: conditions at a particular location can increase (amplify) or decrease the level of shaking that is otherwise expected for a given magnitude and distance. Combining information about site effects with where and how often earthquakes of various magnitudes are likely to occur should provide improved assessments of seismic hazard.
