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!

Magnitude and Slip Scaling Relations for Fault-Based Seismic Hazard

Bruce E. Shaw

Submitted September 11, 2022, SCEC Contribution #11936, 2022 SCEC Annual Meeting Poster #196

Scaling relations play an important role in fault-based seismic haard, where slip rates on faults are balanced by cumulative slip in an earthquake rupture forecast. Here we discuss a series of issues which arise in constructing sets of logic tree branches for use in fault-based hazard estimates. These issues include:
1) depth of rupture; 2) transient deepening following large earthquakes; 3) uncertainty in mean; 4) difficulties in using classical continuum exponent fits; 5) multifault compatability; 6) and minimal models.
Recommendations for minimal branch models are discussed.
