30 Years of Progress in Quantification of Seismic Hazards

Episode 3 of the Northridge 30th Anniversary Webinar Series:
The Northridge Earthquake – 30 Years Later – A Catalyst for Engineering Resilient Communities

Series Partners:

• American Society of Civil Engineers (ASCE) Infrastructure Resilience Division
• ASCE Los Angeles Section
• Earthquake Engineering Research Institute (EERI) Southern California Chapter
• Structural Engineers Association of Southern California (SEOASC)
• Earthquake Country Alliance (ECA), led by the Statewide California Earthquake Center (SCEC)

 
Episode 3 Overview:

There has been an exponential progress in the quantification of seismic hazard since the Northridge Earthquake. In this webinar, after a brief review of the status of seismic hazard assessment in the 1994 era, an overview of the progress in our understanding and quantification of ground motion and fault rupture hazards will be presented.

One major development in the direction of seismic hazards research in the last 30 years has been the initiation and expansion of a series of large community-based research programs on earthquake hazards. These non-traditional collaborative research initiatives have resulted in major advancements in our understanding and modeling of geohazards, and with a wide spectrum of impacts on various issues in earthquake engineering. In this webinar two examples of such large community-based programs, NGA ground motion research series and fault displacement hazard initiative, will be overviewed along with their current status and directions.
