CS7A - Concurrent Session 07A: Seismic Section of the Dam Safety Toolbox

This presentation will discuss proposed refinements to the Seismic section of the Dam Safety Toolbox. The goal is to summarize the current industry standard for the assessment of seismic risk to dams for use by dam owners, regulators and consultants. It will present proposed improvements and expect to receive feedback from the audience. It will include highlight public domain references that represent the current state of practice for seismic analysis and assessment. Topics that will be organized and described include:

• Types of Seismic Evaluations
• Required Data:
o Geologic and Tectonic Setting
 Global Geologic Setting and Plate Tectonics
 Local Geologic Setting
 Local Tectonic Setting
 Velocity Structure
o Seismic Source Characterization
 Background Seismicity
 Areal Sources
 Fault Sources
o Ground Motion Characterization
• Types of Analyses
o PHSA
o DHSA
o Seiches
o Reservoir-triggered Seismicity
• Examples
• Best Practice Resources
• Trainings
• Other Resources
• Citations
