Seismic Section of the Dam Safety Toolbox

ABSTRACT ONLY - 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:
oGeologic and Tectonic Setting
Global Geologic Setting and Plate Tectonics
Local Geologic Setting
Local Tectonic Setting
Velocity Structure
oSeismic Source Characterization
Background Seismicity
Areal Sources
Fault Sources
oGround Motion Characterization
•Types of Analyses
oPHSA
oDHSA
oSeiches
oReservoir-triggered Seismicity
•Examples
•Best Practice Resources
•Trainings
•Other Resources
